Before You Begin  
Congratulations on purchasing one of the most advanced cycles available—the  
Precor EC850 Professional Cycle. Built to the exacting standards of the health  
club environment, the EC850 Professional Cycle can withstand the rigors of  
daily club use with little maintenance.

The easy-to-use electronic console allows users to simply climb on and begin  
cycling. The chosen course is displayed on the three-dimensional course  
simulator along with the rider’s position on the course. Throughout the workout,  
the electronics continually display statistics about distance travelled, pedal  
RPM, time remaining in the program, and fitness score. With the electronic  
pacer, users can easily maintain their intensity and judge their progress.  
To maximize the use of the EC850 Professional Cycle, please study this  
manual thoroughly.  
About this Manual  
Inside this manual, you will find instructions for installing and using the EC850  
Professional Cycle. You will also find an explanation of aerobic conditioning  
and suggestions for developing an EC850 fitness program.  
The manual uses the following conventions for identifying special information:  
Note: Contains additional information that applies to the preceding text.  
Important: Indicates information to which you should pay special attention.

Setting Up the EC850 Professional Cycle  
2
The EC850 Professional Cycle comes fully assembled. You simply need to  
follow the installation requirements listed in this section and place the cycle in  
the appropriate location.  
The cycle has a unique program that lets you determine which language and  
measurement system appears on the electronic console display. You can  
choose one of three languages: French, German, or English, and select either  
U.S. Standard or Metric as the measurement system. The Club Setting Program  
also enables you to limit workout time on the cycle so more people can use it.  
Instructions on how to use the program are found in this section.  
Installation Requirements  
Follow the installation requirements below when installing the cycle. If you do not  
install the cycle according to the following guidelines, you could void the Precor  
warranty.  
Set up the EC850 cycle on a solid, flat surface.  
Use the appropriate voltage outlet and grounding as specified on the  
cycle. The EC850 cycle is available in both 120-volt and 220-volt models.  
Refer to the cycle’s identification label to determine the voltage and fre-  
quency that your cycle needs.  
CAUTION: Do not use a non-grounded outlet. Electrical damage might  
occur if the EC850 cycle is connected to an improper power source.  
Interconnecting Cycles  
You can connect up to eight EC850 cycles together in a “daisy chain” fashion  
which eliminates the need for additional wall outlets.  
To connect the cycles together, take the following steps:  
1. Locate the outlet on the front of the cycle next to the ON/OFF power switch.  
2. Connect the appropriate power cord from the outlet to the next cycle in line.  
Caution: Do not use the outlet located on the front of the cycle for anything  
other than interconnecting EC cycles. Do not connect treadmills or other  
electrical appliances to this outlet.

Using the Club Setting Program  
The Club Setting Program lets you customize your cycle with the following  
features:  
Language—The words displayed on the electronic console can appear in  
one of the three languages (French, German, or English). Typically, on the  
cycle you buy, the language is preset to English.  
Workout time—You can set a workout time limit between 2 and 60  
minutes. For example, if a club owner sets the maximum workout time to  
20 minutes, the cycle would allow users to specify a workout time from 2  
to 20 minutes. Users could not specify a workout time longer than 20  
minutes. When you buy the cycle, it is set to a maximum workout time of  
60 minutes.  
Measurement system—You can choose between U.S. Standard or  
Metric. Typically, the cycle you buy is set to U.S. Standard.  
Accessing the Club Setting program requires combining specific keys on the  
electronic console. This design helps secure the cycle from unauthorized  
access and changes.  
To use the Club Setting program, take the following steps:  
1. Make sure that the cycle is located in an appropriate place and plugged in.  
2. If the cycle is turned OFF, turn it ON using the ON/OFF power switch. This  
switch is located on the front of the cycle, near the power cord.

Using the EC850 Professional Cycle  
The EC850 Professional Cycle is designed so users can work out without  
instruction or training. The directions on the console and the prompts on the  
screen will guide a user through the entire workout session. Before the cycle is  
used, however, we recommend familiarizing yourself with it so it will be used  
safely and effectively. This section covers the following information:

instructions for turning the cycle on and off  
an explanation about using the cycle in manual mode (workout program 0)  
instructions for exercising on the cycle  
instructions for designing a customized exercise program (two custom  
courses can be designed—workout programs 8 and 9)  
Understanding the Electronic Console  
Once the EC850 cycle is set up, it is ready to use. There are no complex  
instructions to follow or mandatory programming steps required to operate the  
cycle. Simply select one of the 10 workout programs, then specify how hard and  
how long you want to work. As you exercise, the electronic console provides  
motivation and presents constant feedback about your progress.  
A screen-saver feature causes the console displays to disappear 2 minutes  
after a workout program ends. If you stop exercising and take more than a 2  
minute break, your workout session ends and the screen-saver feature pro-  
duces blank window displays. While the left and right window displays remain  
blank, “EC850 Press any button to begin exercise” appears and scrolls  
across the bottom window display.  
Diagram 2 illustrates the EC850 electronic console. Its keys and displays are  
explained on the following pages.

Left Display  
Window  
The left display on the electronic console provides information about your  
workout session:  
Program: Indicates the workout program selected for an exercise session. You  
can choose between 0 and 9 by using the arrow keys.  
Level: Shows the selected effort level, from 1 to 9. The higher the number you  
select, the more resistance you receive. You can change the effort level any-  
time during a workout by using the arrow keys to increase or decrease the  
resistance.  
page 9  
 
Pedal RPM: Shows pedal speed in revolutions per minute (RPM). Use this  
display to determine exercise intensity (how hard you are working out) at any  
given moment.  
Fitness Score: Shows a fitness score from 1 to 100 percent. The fitness score  
is associated with the pacer and helps you determine whether or not you are  
using the correct exercise level. To maintain a 100% fitness score you must  
finish the program at the same time as the pacer. You will exceed 100% if you  
finish ahead of the pacer and be below 100% if you finish behind the pacer.  
If you can easily maintain a 100 percent fitness score, you might want to  
choose a more challenging workout next time. However, if you have difficulty  
maintaining a high enough score, you might want to choose a lower exercise  
level.  
Watts: Indicates the amount of energy currently being expended.  
Calories per Hour: Indicates the number of calories burned per hour. Use this  
display, along with Calories Used and Pedal RPM, to determine exercise  
intensity (how hard you are working out) at any given moment.  
Calories Used: Provides the number of calories burned in the workout. The  
cycle determines calories based on a 160 pound rider, so if your weight is  
different, you should use the displayed information only as a reference.  
Distance: Shows how far you have travelled, in either miles or kilometers. Use  
this information to measure total work accomplished during a workout.  
Time: Lists the amount of time remaining on the course you are using. Use this  
display to pace yourself during a workout.  
Goal Setting: Indicates the anticipated targets the user will achieve at the  
selected program or effort level. The goals you set are affected by the speed,  
workload, and time of your workout session. When you enter a time after the  
Enter Workout Time” prompt, the display “Your Goals Are” appears in the left  
window display and provides the basis for your workout and performance  
summary.  
Right Display  
Window  
The right display window on the electronic console prompts you to enter specific  
information, graphically displays a pacer, and provides information about  
incline:  
Pace Tempo: Provides a tempo for you to follow. The pacer provides motiva-  
tion and helps you maintain exercise intensity. During a workout, if you change  
the effort level, the pace tempo changes to reflect the new level.  
While you workout, the console displays a roadway with two triangles, one on  
each side of the centerline. The shaded triangle on the left side is the pacer; the  
triangle on the right side represents you.  
If your speed remains even with the pacer, the triangles remain the same size.  
If you are behind the pacer, the pacer appears to move ahead and become  
smaller in size. When your speed is greater than the pacer’s, the triangle that  
page 10  
 
represents you appears to move ahead and become smaller in size.  
Hill Profile: Appears in the upper right-hand corner of the screen. It provides a  
graphic representation of the current grade of incline in the course. Below this  
window, you will see a number that represents the relative effort level of that  
part of the course. A “1” represents the easiest and a “9” represents the most  
difficult level.  
Performance Summary: Appears at the end of your workout. The workout  
statistics appear as a percent of your goals and indicate whether or not you met  
the goals you set for the total calories burned, distance covered, and time  
elapsed. Review your workout statistics to determine how well you did.  
Bottom Display  
Window  
Program Profile: The course profile that appears in the bottom window display  
corresponds to the program you selected. As you proceed through your work-  
out, the left portion of the profile becomes shaded indicating the course seg-  
ments you have already completed.  
Adjusting the Seat  
Before starting a workout, you should position the seat properly to avoid strain  
on your knees. Take the following steps to adjust seat height.  
1. To check for proper seat position, sit on the seat of the cycle with both feet  
in the pedals (make sure that the balls of your feet are centered on the  
pads). The knee of the extended leg should be slightly bent, 10 to 15

3. Slide the seat post up or down into the desired position.  
4. Release the seat post adjustment pin.  
CAUTION: Make sure that the seat is securely in place before using  
the cycle for a workout.  
5. Before sitting on the cycle, press down firmly on the seat to make sure no  
slippage occurs and the pin is properly seated in the appropriate hole.  
6. Sit on the cycle’s seat again and, if necessary, follow steps 2 through 5 to  
readjust the seat height.  
Adjusting the Handlebars  
You can adjust the handlebars on the EC850 within a six inch adjustment span  
to provide the most comfortable ride possible.  
To adjust the handlebars, take the following steps:  
1. Sit on the cycle with your hands on the handlebars. You should be in a  
relaxed, comfortable riding position.  
2. If you need to adjust the handlebars, dismount and locate the lever on the  
right side of the console column.  
3. Loosen the handlebar shaft by turning the lever counterclockwise.  
4. Place your hands on the lower flat portion of the handlebars (one of each  
page 12  
 
 
side of the handlebar shaft).  
5. Pull the handlebars toward you to decrease the distance between the seat  
and the handlebars. (Slide the handlebars in the opposite direction to  
increase the distance).  
Note: You can increase or decrease the distance between the seat and the  
handlebars within a 6 inch span. You cannot pull the handlebar shaft  
completely out of the console column because a safety bar holds the shaft  
in place.  
6. When you feel that the handlebars are in the proper position, tighten the  
lever by turning it clockwise.  
Important: Do not sit on the seat and adjust the handlebars. Be sure the  
handlebars are secure before you mount the cycle.  
7. Sit on the cycle in a comfortable riding position with your hands on the  
handlebars. If necessary, follow steps 2 through 6 to readjust the handle-  
bars.  
Turning the Cycle ON and OFF  
Use the ON//OFF power switch to turn the cycle ON and OFF. This switch is  
located on the front of the cycle, near the power cord. It takes about 45 seconds  
for the electronic console displays to appear after the cycle has been turned ON  
and you press the ON key.  
Use the ON//OFF power switch to turn OFF the cycle when it is not being used  
for any length of time. For example, have the cycle turned OFF during non-  
business hours.  
Using Manual Mode (Workout Program 0)  
In addition to choosing a preprogrammed or custom course, you can choose  
manual mode. Manual mode is the same as the workout program “0,” which lets  
you control your effort level while the program is in progress.  
After you select program “0,” the program’s course profile appears in the bottom  
window display and shows a flat, constant course. The Hill Profile appears in  
the upper right corner of the right window display and indicates an incline level  
of 5. Use the arrow keys to change your effort and incline levels; as you change  
the levels, the segments in the profiles also change.  
A low level profile represents the least amount of effort required and the  
lowest number of calories burned.  
A high level profile represents the highest amount of effort required and the  
greatest number of calories burned.  
page 13  
 
   
As you proceed through your workout, the left portion of the course profile  
becomes shaded indicating the course segments you have already completed.  
Exercising on the EC850 Cycle  
This section explains how to exercise on the cycle. The EC850 comes with  
seven preprogrammed courses. These courses differ in the “terrain” you cover.  
Each course includes warm-up and cool-down intervals appropriate to the total  
course length.  
All seven preprogrammed courses can be performed at any of the nine effort  
levels. To select the effort level appropriate for your level of fitness, start with  
level 1 (beginner exercise). If you receive a score of 100 percent, continue to  
the next highest level. Each time you receive a 100 percent score, you should  
advance to the next effort level for a more challenging workout.  
Note: The fitness score is associated with the pacer and helps you determine  
whether or not you are using the correct exercise level. To maintain a 100%  
fitness score you must finish the program at the same time as the pacer. You  
will exceed 100% if you finish ahead of the pacer and be below 100% if you  
finish behind the pacer.  
In addition to the preprogrammed courses, you can choose a custom course  
that you or the club owner has designed. Two custom courses can be created  
(for instructions, see Designing a Customized Course later in this section). You  
can also select manual mode (program 0) which lets you control your effort  
level while the program is in progress.  
Once you have answered the start-up prompts and started exercising in a  
workout program, you can exit the program by pressing ENTER/RESET.  
Pressing this key cancels the program. The cycle displays your Performance  
Summary, then the initial start-up prompt.  
CAUTION: Before beginning any fitness program, you should have a  
complete physical examination by your physician.  
To exercise on the cycle, take the following steps:  
1. Check to see that the cycle is turned ON. If it is turned OFF, turn it ON  
using the ON/OFF power switch. This switch is located on the front of the  
cycle, near the power cord.  
2. Sit on the cycle. Make sure that your weight is balanced and your feet are  
positioned securely, with the balls of your feet centered on the pads. You  
might need to adjust the seat and handlebars to comfortable positions.  
(Refer to Adjusting the Seat and Adjusting the Handlebars for instructions.)  
3. Press the ON key. The initial start-up prompt, “Choose Workout Program”  
page 14  
 
 
appears.  
Note: If the cycle is already ON and EC850 is scrolling across the bottom of  
the display. You can press any key and the initial start-up prompt, “Choose  
Workout Program” will appear.  
4. Once the “Choose Workout Program” prompt appears, select a program  
using the arrow keys.

Note: To repeat the exact workout again, you need to specify the same  
effort level number in addition to the program number.  
7. Once the desired effort level number appears, press ENTER/RESET. The  
Enter Workout Time” prompt appears.  
8. Use the arrow keys to specify how long you want to work out. The displays  
in the left window (Calories Used, Distance, and Time) change as you scroll  
through the units of time. When the desired amount of time is displayed,  
press ENTER/RESET.  
The Club Settings program lets club owners limit the length of time allowed  
for a workout. When specifying a workout time, you can choose any time up  
to, but not longer than, this limit. For example, if the time limit is at 30  
minutes, you can set a workout time from 2 to 30 minutes. You cannot  
specify a workout time longer than 30 minutes.  
After you enter a workout time, the Goal Setting display “Your Goals Are”  
appears in the left window showing the target amounts you can achieve  
with the workout selected.  
9. To start your workout, begin pedaling.  
During a workout, you can change your effort level using the arrow keys.  
Doing this affects how hard you work, but does not change the profile of the  
course unless you are using Manual mode (program 0).  
10. Continue your workout until the program ends. Maintain your exercise  
intensity by pedaling with the pacer.  
Note: We do not recommend exercising faster than the pacer since it is  
provided to help you work out. If you want a more difficult exercise session,  
select a different program or a higher effort level.  
11. When the selected exercise program ends, review your performance  
page 16  
 
summary.  
We recommend that you keep track of your workouts by writing them down.  
This way you can monitor your progress toward your fitness goals and also use  
the information as a reference in planning interesting and challenging workouts  
in the future.  
Designing a Customized Course  
The EC850 Professional Cycle lets you design two custom courses: program  
“8” and program “9.” To access these courses, you need to press a specific  
combination of keys on the electronic console. This design helps secure the  
cycle from unauthorized access and changes.  
To design a custom course, take the following steps:

advise on training, technique, and exercise physiology. Your dealer can also  
recommend good books on these subjects.  
To help you get started in planning and carrying out your fitness program, this  
section provides some basic information on aerobic exercise—such as how  
hard you should workout, how long each session should be, and how often you  
need to exercise to benefit from a regular program.  
How Hard Should I Exercise?  
Studies show that to achieve the benefits of aerobic exercise, it is necessary to  
work out hard enough to raise your heart rate to a certain minimum level, called  
the “training zone.” Your training zone depends on your age and level of fitness.  
Refer to Diagram 6 to determine your training zone. Keep in mind that this zone  
is an approximation, to be used as a guideline—individual heart rates vary  
according to several physiological factors. To determine your training zone, or

YOUR AGE  
target heart rate, find your age and fitness level on the diagram, and then find  
the line where they intersect. For example, if you are 35 years old, your training  
heart rate at the intermediate fitness level is 157 beats per minute. Remember  
this number—this is the pulse rate you should try to maintain as you work out.  
To determine your heart rate, take your pulse at a place that you can reach  
easily and comfortably while you exercise. Typical places for measuring heart  
rate are directly over the heart on the left side of the chest, on either side of the  
page 20  
 
 
neck, over the temple, or on the thumb side of either wrist. Wherever you  
measure your pulse, make sure that you use your index and middle fingers—  
not your thumb. Your thumb has a strong pulse which can affect your heart rate  
reading.  
Once you locate your pulse, look at a clock with a second hand, and count the  
beats for six seconds. Multiply that number by 10 to determine the total number  
of beats per minute. For example, if you count 14 beats over six seconds, the  
total number of beats per minute is 140. Compare the total number of beats  
with your training zone as identified in Diagram 6. If necessary, increase or  
decrease your activity to bring your heart rate into your training zone. You can  
regulate how hard you (and your heart) work by choosing different effort levels.  
Remember—your heart rate is the definitive measure of how hard you are  
working.  
Regardless of your fitness level, avoid doing too much too soon. Selecting too  
hard a course or too high an effort level are common errors. Give yourself time  
to become familiar with your cycle and to improve your fitness level. Then you  
can gradually increase the effort level or course difficulty to make your workouts  
more challenging.  
How Long Should I Exercise?  
The length of each exercise session depends on your fitness level. Exercise  
physiologists have determined that, to attain cardiovascular benefits from  
exercise, you should maintain your heart rate in its training zone for at least 15  
minutes. This is in addition to your warm-up time, and does not include cool  
down. You should always allow several minutes to bring your heart rate into  
your training zone, by starting out slowly and gradually increasing work level.  
Similarly, use several minutes of light exercise after the workout to bring your  
heart rate down to near resting level.  
The higher your fitness level, the longer you should maintain your heart rate in  
the training zone (between 20 and 30 minutes). Beginners should always start  
slowly, and gradually increase their sessions to 20 minutes or more.  
How Often Should I Exercise?  
Research indicates that aerobic sessions of 20 minutes or more should be done  
at least three to five times a week to obtain significant cardiovascular benefits.  
Most experts agree that sensible eating habits and regular aerobic exercise are  
the keys to weight control and fitness. A recent study, which tracked several  
subjects over a period of years, conclusively showed that exercise, not dieting,  
is the key factor to long-term weight loss.

Maintaining the EC850 Professional Cycle  
5
Because of its advanced design, the EC850 cycle requires little maintenance  
beyond periodic cleaning, which is explained in this section. Keep in mind that,  
as owner of this machine, you are solely responsible for its maintenance.  
If you encounter problems with the cycle, follow the instructions in Using the  
Diagnostic Program. This program performs some basic diagnostic routines that  
can help you troubleshoot problems.  
CAUTION: Unplug the cycle from the power outlet before performing any  
maintenance tasks, such as cleaning.  
Cleaning the Cycle  
Clean the outer cabinet using normal over-the-counter products made for  
cleaning plastic and rubber. Do not use these products on the electronic con-  
sole since they will scratch its surface.  
Clean the surface of electronic console with a damp sponge or soft cloth. You  
can use mild soap and warm water (not hot) to clean the console. Dry the  
surface thoroughly with a clean towel.  
Important: Do not pour liquids on the electronic console and take special care  
when cleaning the electronic console display to avoid scratching its surface.  
Using the Diagnostic Program  
The EC850 cycle provides a Diagnostic program to help you troubleshoot most  
problems that might arise. When you first access this program, it automatically  
tests the operation of the main computer functions. If these functions pass, you  
can test the operation of the keys and the speed sensor, Hall 1. If any test fails,  
the EC850 cycle must be serviced. See Getting Service for details.  
Note: The speed sensor, Hall 2, is not used on the EC850 cycle.  
Accessing the Diagnostic program requires pressing a specific combination of  
keys on the electronic console. This design helps secure the cycle from unau-  
thorized access and changes.  
To access the Diagnostic program, take the following steps:  
1. If the cycle is turned off, turn it ON using the ON/OFF power switch.  
page 22  
 
   
2. Press the ON key. The initial start-up prompt, “Choose Workout Program”  
appears. (The display may take a minute to appear.)  
Note: If the cycle is already ON and EC850 is scrolling across the bottom of  
the display, press any key and the initial start-up prompt will appear.  
3. When the “Choose Workout Program” prompt appears, access the  
Diagnostic program by simultaneously holding down the ON and ENTER/  
RESET keys for a minimum of 5 seconds.  
4. Release the keys when you see the Diagnostic screen as shown in  
Diagram 7.

5. Watch the screen as the Diagnostic program automatically executes six  
tests. These tests check the operating condition of several of the main  
computer functions. All six of these tests must succeed before the displays  
in the right and bottom windows appear.

6. Using the Diagnostic screen, test the keypad operation by pressing each  
key and watching the right window display.  
The display has a graphic representation of the four keys. When you press  
a key and it is operating correctly, the corresponding box will highlight. If the  
box does not highlight when a key is pressed, or if the box remains high-  
lighted after the key is released, the electronic console overlay might be  
defective.

7. Test the Hall 1 speed sensor by SLOWLY moving the pedals. Continue  
pedaling for about 1 minute. The asterisk to the right of “Hall 1” will blink on  
and off if the sensor is working correctly. If the asterisk stays solid, the cycle  
needs servicing. Please note that only Hall 1 is used; ignore Hall 2.  
8. To exit the Diagnostic program, either turn the cycle OFF then ON, or press  
ENTER/RESET three times. In either case, the initial start-up prompt,  
Choose Workout Program,” appears.
