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  
LED Track  
Mode Indicators  
scan mode is selected, and a flashing mode indica-  
tor will show which mode is currently displayed.  
Note: If a different mode is selected, you can  
select the scan mode again by repeatedly pressing  
the mode button.  
SpeedÑThis mode displays your current exercise  
speed, in miles per hour.  
Speed, time,  
distance, laps,  
or calorie modeÑ

have completed, in miles.  
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 7 on page 8.  
10  
 
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 7 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.

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.
