Precautions
Interference During Exercise
Electromagnetic Interference and Exercise Equipment
Disturbance may occur near microware ovens and computers. Also WLAN base stations may cause
interference when exercising with CS600X. To avoid erratic reading or misbehaviors, move away from
possible sources of disturbance.
Exercise equipment with electronic or electrical components such as LED displays, motors and
electrical brakes may cause interfering stray signals. To solve these problems, try the following:
1. Remove the transmitter from your chest and use the exercise equipment as you would normally.
2. Move the cycling computer around until you find an area in which it displays no stray reading or
does not flash the heart symbol. Interference is often strongest directly in front of the display
panel of the equipment, while the left or right side of the display is relatively free of disturbance.
3. Put the transmitter back on your chest and keep the cycling computer in this interference-free
area as much as possible.
If the cycling computer still does not work with the exercise equipment, it may be electrically too noisy
for wireless heart rate measurement.
Minimizing Risks When Exercising
Exercise may include some risk. Before beginning a regular exercise program, it is recommended that
you answer the following questions concerning your health status. If you answer yes to any of these
questions, we recommend that you consult a doctor before starting any training program.
• Have you been physically inactive for the past 5 years?
• Do you have high blood pressure or high blood cholesterol?
• Do you have symptoms of any disease?
• Are you taking any blood pressure or heart medication?
• Do you have a history of breathing problems?
• Are you recovering from a serious illness or medical treatment?
• Do you use a pacemaker or other implanted electronic device?
• Do you smoke?
• Are you pregnant?
Note that in addition to exercise intensity, medications for heart conditions, blood pressure,
psychological conditions, asthma, breathing, etc., as well as some energy drinks, alcohol, and nicotine
may also affect heart rate.
It is important to be sensitive to your body’s responses during exercise. If you feel unexpected pain or
excessive fatigue when exercising, it is recommended that you stop the exercise or continue at a lighter
intensity.
Notice to individuals with pacemakers, defibrillators or other implanted electronic devices. Individuals
who have a pacemaker use the Polar cycling computer at their own risk. Before starting use, we always
recommend a maximal exercise stress test under a doctor’s supervision. The test is to ensure the safety
and reliability of the simultaneous use of the pacemaker and the Polar cycling computer.
