BATTERIES
POLAR TRANSMITTER
The estimated average battery life of the Polar Transmitter is
2500 hours of use. Contact Polar authorized Service Center
for a transmitter replacement.
Service on the page 29 for detailed instructions.
Polar recycles used transmitters.
POLAR TEMPO RECEIVER
The estimated average battery life of the Polar Tempo 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.
It is not recommended to 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 Polar authorized Service Center. At the
same time a full periodic check of the Polar Heart Rate
Monitor will be done. Contact Polar Electro Inc.
Service on the page 29 for detailed instructions.

Precautions
POLAR HEART RATE MONITOR
IN A WATER ENVIRONMENT
Polar Heart Rate Monitors are water resistant to 20 meters. To
maintain the water resistance, it is strongly recommended to
have all service done by an authorized Polar Service Center.
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 the electrodes of Polar Transmitter
may get short circuited and ECG signals 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.
POLAR HEART RATE MONITOR AND
INTERFERENCE
ELECTROMAGNETIC INTERFERENCE
Disturbances may occur near high voltage power lines, traffic
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.
