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 exercising. 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
mode indicator
will show that the

mode button repeatedly. The mode indicators will
show which mode is selected. (Make sure that the
scan mode is not selected.)
LapsÑThis mode displays the number of 1/4-mile
laps you have completed around the LED track.
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.
CalorieÑThis mode displays the approximate number
of Calories you have burned.
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.
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.
BATTERY INSTALLATION
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 8.

MAINTENANCE
Inspect and tighten all parts of the PROFORM¨ 485E
regularly. Replace any worn parts immediately.
CONSOLE TROUBLE-SHOOTING
If the console does not function properly, the batteries
should be replaced. To replace the batteries, refer to
assembly step 8 on page 8.
The 485E can be wiped clean with a soft cloth and
mild detergent. Do not use abrasives or solvents.
To prevent damage to the console, keep liquids away
from the console. Use only a sealable water bottle in
the console.
STORAGE
When storing the 485E, remove the batteries from the
console. Keep the 485E in a clean, dry location, away
from moisture and dust.

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.
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.
WARNING: Before beginning this or any exer-
cise program, consult your physician. This is
especially important for persons over the age
of 35 or persons with pre-existing health
problems.
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.
Aerobic Exercise
EXERCISE INTENSITY
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.
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
burning, and cardiovascular (aerobic) exercise.
HOW TO MEASURE YOUR HEART RATE
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
heartbeat 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.)
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.
WORKOUT GUIDELINES
Each workout should include the following three
important parts:
Burning Fat
A warm-up, consisting of 5 to 10 minutes of stretch-
ing and light exercise. (See page 13.) A proper warm-
up increases your body temperature, heart rate, and
circulation in preparation for exercise.
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
12

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.)
EXERCISE FREQUENCY
To maintain or improve your condition, plan three work-
outs each week, with at least one day of rest between
workouts. After a few months of regular exercise, 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 excessive
training may result in injury to your health.
Remember, the key to success is make exercise a
regular and enjoyable part of your everyday life.
A cool-down, with 5 to 10 minutes of stretching.
This will increase the flexibility of your muscles
and will help to prevent post-exercise problems.
SUGGESTED STRETCHES
The correct form for several basic stretches is shown at the
right. Move slowly as you stretchÑnever bounce.
1
1. Toe Touch Stretch
Stand with your knees bent slightly and slowly bend forward
from your hips. Allow your back and shoulders to relax as you
reach down toward your toes as far as possible. Hold for 15
counts, then relax. Repeat 3 times. Stretches: Hamstrings,
back of knees, and back.
2
2. Hamstring Stretch
Sit with one leg extended. Bring the sole of the opposite foot

counts, then relax. Repeat 3 times for each leg. Stretches:
Hamstrings, lower back, and groin.
3. Calf/Achilles Stretch
3
With one leg in front of the other, reach forward and place
your hands against a wall. Keep your back leg straight and
your back foot flat on the floor. Bend your front leg, lean for-
ward and move your hips toward the wall. Hold for 15 counts,
then relax. Repeat 3 times for each leg. To cause further
stretching of the achilles tendons, bend your back leg as well.
Stretches: Calves, achilles tendons, and ankles.
