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
