DESCRIPTION OF THE CONSOLE
HOW TO OPERATE THE CONSOLE
The console is designed to help you get the most
from your workouts. As you exercise, you can watch
your progress around the LED track, while the
display provides continuous exercise feedback.
The six modes of the display are described below.
If there is a thin sheet of clear plastic on the face of
the console, remove it.
1. To turn on the power, press the on/reset button or
simply begin pedaling. When the power is turned
on, one LED indicator will light in the LED track,
and the entire display will appear for two seconds.
The console will then be ready for operation.
2. Select one of the five modes:
Scan modeÑ
When the power
is turned on, the
scan mode will
automatically be
selected. One

laps you have completed around the LED track.
CalorieÑThis mode displays the approximate number
of Calories you have burned.
3. The LED track represents a distance of 1/4 mile.
As you exercise, the indicators around the track
will light one at a time until you have completed 1/4
mile. A new lap will then begin.
ScanÑThis mode displays the speed, time, distance,
laps, and calorie modes, for 5 seconds each, in a
repeating cycle.
4. To reset the display, press the on/reset button.
BATTERY INSTALLATION
5. To turn off the power, simply wait for about four
minutes. Note: The console has an Òauto-offÓ
feature. If the pedals are not moved and the
console buttons are not pressed for four
minutes, the power will turn off automatically
in order to conserve the batteries.
Before the console can be operated, two ÒAAÓ batter-
ies must be installed. If you have not installed batter-
ies, see assembly step 8 on page 6.

MAINTENANCE AND TROUBLE-SHOOTING
Inspect and tighten all parts of the PROFORM¨ 775s
regularly. The 775s can be cleaned with a soft, damp
cloth. To prevent damage to the console, keep liquids
away and keep the console out of direct sunlight.
Reed Switch is correctly adjusted, reattach the left
side shield.
HOW TO ADJUST THE DRIVE BELT
BATTERY REPLACEMENT
If the you can feel the pedals slip when you are exer-
cising, especially when the resistance knob is turned
to the maximum setting, the Drive Belt (19) may need
to be adjusted. To adjust the Drive Belt, both side
shields must be removed. Refer to the instructions at
the left to remove the left side shield. Remove the
right side shield in the same manner.
If the console does not function properly, the batteries
should be replaced. To replace the batteries, refer to
assembly step 8 on page 6.
HOW TO ADJUST THE REED SWITCH
If the console does not display correct feedback, the
reed switch should be adjusted. In order to adjust the
reed switch, the Left Side Shield (6) must be
removed. First, using an adjustable wrench, turn the
Left Pedal (45) clockwise to remove the Pedal from
the left arm of the Crank (29).
Loosen the M8
Flanged Hex Nut
(36) on each side of
the Flywheel (42).
Tighten the M6 Nut
(39) on each M6
Eyebolt (37) until the

tight. Be sure that
you tighten each
M6 Nut an equal
amount. Once the

CONDITIONING GUIDELINES
The following guidelines will help you to plan your
exercise program. Remember that proper nutrition and
adequate rest are essential for successful results.
Aerobic Exercise
If your goal is to strengthen your cardiovascular sys-
tem, your exercise must be Òaerobic.Ó Aerobic exer-
cise is activity that requires large amounts of oxygen
for prolonged periods of time. This increases the
demand on the heart to pump blood to the muscles,
and on the lungs to oxygenate the blood. For aerobic
exercise, adjust the intensity of your exercise until
your heart rate is near the largest number in your
training zone.
WARNING: Before beginning this or any exer-
cise program, consult your physician. This is
especially important for persons over age 35
or persons with pre-existing health problems.
EXERCISE INTENSITY
HOW TO MEASURE YOUR HEART RATE
Whether your goal is to burn fat or to strengthen your
cardiovascular system, the key to achieving the
desired results is to exercise with the proper intensity.
The proper intensity level can be found by using your
heart rate as a guide. The chart below shows recom-
mended heart rates for fat burning, maximum fat burn-
ing, and cardiovascular (aerobic) exercise.
To measure your heart
rate, first exercise for
at least four minutes.
Then, stop exercising
and place two
fingers on your wrist
as shown. Take a six-
second heartbeat
count, and multiply the
result by 10 to find
your heart rate. For example, if your six-second heart-
beat count is 14, your heart rate is 140 beats per
minute. (A six-second count is used because your
heart rate will drop rapidly when you stop exercising.)
WORKOUT GUIDELINES
To find the proper heart rate for you, first find your age
at the bottom of the chart (ages are rounded off to the
nearest ten years). Next, find the three numbers
above your age. The three numbers are your Òtraining
zone.Ó The smallest number is the recommended
heart rate for fat burning; the middle number is the
heart rate for maximum fat burning; the largest
number is the heart rate for aerobic exercise.
Each workout should include the following three
important parts: A warm-up, consisting of 5 to 10 min-
utes of stretching and light exercise. A proper warm-
up increases your body temperature, heart rate, and
circulation in preparation for exercise. Training zone
exercise, consisting of 20 to 30 minutes of exercising
with your heart rate in your training zone. (During the
first few weeks of your exercise program, do not keep
your heart rate in your training zone for longer than 20
minutes.) A cool-down, with 5 to 10 minutes of
Burning Fat
stretching. This will increase the flexibility of your mus-
cles and will help to prevent post-exercise problems.
To burn fat effectively, you must exercise at a rela-
tively low intensity level for a sustained period of time.
During the first few minutes of exercise, your body
uses easily accessible carbohydrate calories for ener-
gy. Only after the first few minutes of exercise does
your body begin to use stored fat calories for energy.
If your goal is to burn fat, adjust the intensity of your
exercise until your heart rate is near the smallest
number in your training zone as you exercise.
EXERCISE FREQUENCY
To maintain or improve your condition, plan three
workouts each week, with at least one day of rest
between workouts. After a few months of regular exer-
cise, you may plan up to five workouts each week, if
desired. Caution: Be sure to progress at your own
pace and avoid overdoing it. Incorrect or exces-
sive training may result in injury to your health.
Remember, the key to success is to make exercise a
regular and enjoyable part of your everyday life.
For maximum fat burning, adjust the intensity of your
exercise until your heart rate is near the middle num-
ber in your training zone as you exercise.
