Changing Wrist Unit Batteries
Do not open the wrist unit yourself. To ensure
water resistance properties and the use of
qualified components, the wrist unit battery
should be replaced by an authorized Polar Service
Center only. A full periodic check of the heart rate
monitor will be done when changing batteries.
The low battery symbol will appear when 10-15%
of the battery capacity is left. The backlight and
sounds are automatically deactivated. Excessive
use of the backlight drains the battery more
rapidly. In cold conditions, the low battery
indicator may appear, and disappear again when
you return to a warmer environment.
Changing Transmitter Batteries
If you suspect that the transmitter battery has run
out, contact your authorized Polar Service Center
for a replacement transmitter. Polar recycles used
transmitters.
