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:
• an overview of the features provided on the electronic console
• information about adjusting seat height
• information about adjusting the handlebars
• 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 produces 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.

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.
page 12
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
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 handlebars.
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 nonbusiness 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
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

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.
page 16
11. When the selected exercise program ends, review your performance
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.

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.
page 20
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
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
Diagnostic Program
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 console 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
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 unauthorized 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.

for details.
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

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 highlighted 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.
