8. PRECAUTIONS
The Polar cycling computer shows your performance 
indicators. It indicates the level of physiological strain 
and intensity during your exercise. It also measures speed 
and distance when cycling with a Polar speed sensor. 
The 
Polar cadence sensor is designed to measure cadence when 
cycling. 
No other use is intended or implied.
Electromagnetic Interference
Disturbances may occur near high voltage power lines, 
traffi c lights, overhead lines of electric railways, electric bus 
lines or trams, televisions, car motors, bike computers, some 
motor driven exercise equipment, cellular phones, or when 
you walk through electric security gates.
Minimizing Risks When Training
Training may include some risk. Before beginning a regular
training program, answer the following questions concerning 
your health status. If you answer yes to any of these
questions, consult a physician before starting any training
program.
•  Have you been physically inactive for the past 5 years?
•  Do you have high blood pressure or high blood choles-
terol?
•  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 another implanted electronic 
device?
•  Do you smoke?
•  Are you pregnant?
In addition to exercise intensity, medications for heart con-
ditions, 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.
Note! If you are using a pacemaker, you can use Polar 
training computers. In theory interference to pacemaker 
caused by Polar products should not be possible. In
