• Keep the air pressure channels (three openings on the wrist receiver
backcover) clean to make sure that the altitude and temperature
measurements work. Do not insert any objects into the openings.
• Do not immerse the speed sensor in water.
• Avoid hard hits to the speed sensor as these may cause damage.
Batteries
Transmitter
The estimated average battery life of the transmitter is 2500 hours of
use. Contact your distributor/ dealer for a transmitter replacement. Polar
recycles used transmitters. See your Customer Care Charter for detailed
instructions.
Wrist receiver
The estimated average battery life of the wrist receiver is 2 years in
normal use (2h/ day, 7 days a week). Note also that excessive use of the
backlight and the alarm signals will use the battery 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 an authorised Polar Service Centre.
At the same time a full periodic check of the Polar heart rate monitor
will be done.
Battery Replacement for Speed Sensor
The estimated average battery life of the speed sensor is 2500 hours of
use. We highly recommend you send the speed sensor to an authorised
Polar Service Centre for battery replacement, where the unit is tested
after the battery has been replaced. However, if you prefer changing
the battery yourself, please follow these instructions carefully:
