installed and used in accordance with the instructions, may cause harmful interference to radio communications.
However, there is no guarantee that interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be determined by turning the equipment off
and on, try to correct the interference by one or more of the following measures:
•
•
•
•

Reorient or relocate the receiving antenna.
Increase the separation between the equipment and the receiver.
Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
Consult the dealer or an experienced radio/TV technician for help.

FCC CAUTION: To assure continued compliance, use only shielded interface cables when connecting to
computer or peripheral devices. Changes or modifications not expressly approved by the party responVLEOHIRUFRPSOLDQFHFRXOGYRLGWKHXVHU·VDXWKRULW\WRRSHUDWHWKLVHTXLSPHQW

MAINTENANCE AND TROUBLESHOOTING
MAINTENANCE

HOW TO ADJUST THE REED SWITCH

Regular maintenance is important for optimal
performance and to reduce wear. Inspect and properly
tighten all parts each time the exercise bike is used.
Replace any worn parts immediately.

If the console does not display correct feedback, the
reed switch should be adjusted.
See the EXPLODED DRAWING on page 23.
Identify the Right Shield (15). Remove the five
M4 x 16mm Screws (81) from the Right Shield, and
then carefully pull the Right Shield away from the exercise bike.

To clean the exercise bike, use a damp cloth and a
small amount of mild detergent. IMPORTANT: To
avoid damage to the console, keep liquids away
from the console and keep the console out of
direct sunlight.

Note: For clarity, the Right Shield is not shown
in the drawing below. Locate the Reed Switch (29)
and slightly loosen the two M5 x 12mm Screws (79).
Next, rotate the Right Crank Arm (18) until a Magnet
(90) is aligned with the Reed Switch. Slide the Reed
Switch slightly toward or away from the Magnet. Then,
retighten the M5 x 12mm Screws. Repeat this step
until the console displays correct feedback.

CONSOLE TROUBLESHOOTING
If the console display becomes dim, replace the
batteries (see assembly step 10 on page 9); most
console problems are the result of low batteries.

When the console displays correct feedback, reattach
the right shield.

EXERCISE GUIDELINES
Burning Fat—To burn fat effectively, you must exercise at a low intensity level for a sustained period of
time. During the first few minutes of exercise, your
body uses carbohydrate calories for energy. 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 lowest number in your training
zone. For maximum fat burning, exercise with your
heart rate near the middle number in your training
zone.

WARNING:

Before beginning this
or any exercise program, consult your physician. This is especially important for persons
over age 35 or persons with pre-existing
health problems.
The heart rate monitor is not a medical device.
Various factors may affect the accuracy of
heart rate readings. The heart rate monitor is
intended only as an exercise aid in determining heart rate trends in general.

Aerobic Exercise—If your goal is to strengthen your
cardiovascular system, you must perform aerobic
exercise, which is activity that requires large amounts
of oxygen for prolonged periods of time. For aerobic
exercise, adjust the intensity of your exercise until your
heart rate is near the highest number in your training
zone.

These guidelines will help you to plan your exercise
program. For detailed exercise information, obtain a
reputable book or consult your physician. Remember,
proper nutrition and adequate rest are essential for
successful results.

WORKOUT GUIDELINES

EXERCISE INTENSITY

Warming Up—Start with 5 to 10 minutes of stretching and light exercise. A warm-up increases your body
temperature, heart rate, and circulation in preparation
for exercise.

Whether your goal is to burn fat or to strengthen your
cardiovascular system, exercising at the proper intensity is the key to achieving results. You can use your
heart rate as a guide to find the proper intensity level.
The chart below shows recommended heart rates for
fat burning and aerobic exercise.

Training Zone Exercise—Exercise for 20 to 30 minutes 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.) Breathe regularly and deeply as you
exercise; never hold your breath.
Cooling Down—Finish with 5 to 10 minutes of stretching. Stretching increases the flexibility of your muscles
and helps to prevent post-exercise problems.
EXERCISE FREQUENCY

To find the proper intensity level, find your age at the
bottom of the chart (ages are rounded off to the nearest ten years). The three numbers listed above your
age define your “training zone.” The lowest number is
the heart rate for fat burning, the middle number is the
heart rate for maximum fat burning, and the highest
number is the heart rate for aerobic exercise.

To maintain or improve your condition, complete three
workouts each week, with at least one day of rest
between workouts. After a few months of regular exercise, you may complete up to five workouts each week,
if desired. Remember, the key to success is to make
exercise a regular and enjoyable part of your everyday
life.
