Precautions
USING A POLAR HEART RATE MONITOR
IN A WATER ENVIRONMENT
Polar Fitwatch receiver is water resistant to 20 meters.
To maintain the water resistance, do not operate the buttons of
the Polar Wrist Receiver under water. The pressure may cause
the Receiver to leak.
Heart rate measurement in a water environment is technically
demanding for the following reasons:
• Pool water with a high chlorine content and seawater may
be very conductive and therefore short circuit the ECG
signal so that it cannot be detected by the Transmitter unit.
• Jumping into the water or strenuous muscle movement
during competitive swimming may cause water resistance
that shifts the Transmitter on the body to a location where it
is not possible to pick up ECG signal.
• The ECG signal strength varies depending on the individual’s
tissue composition and the percentage of people who have
problems in heart rate measuring is considerably higher in
a water environment than in other use.
BATTERIES
POLAR TRANSMITTER
The estimated average battery life of the Polar Transmitter is
2500 hours of use. Contact your distributor/dealer for a
Transmitter replacement.
See Service for detailed instructions.
Polar recycles used Transmitters.
POLAR WRIST RECEIVER
The estimated average battery life of the Polar Wrist Receiver
is 1 year in normal use (2h/day, 7 days a week). However,
because the battery is inserted at the factory, the actual life of
your first battery once in your possession may be less than the
estimated battery life. Note also that an excessive use of the
backlight and the beep signal will shorten the battery life
more rapidly.
Do not open the Polar Wrist Receiver yourself. To ensure the
water resistance properties and the use of qualified
components, the Wrist Receiver battery should be replaced
only by a person authorised by Polar Electro Oy. At the same
time a full periodic check of the Polar Heart Rate Monitor will
be done. Service for detailed instructions.
