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.
