OK button twice, after which the Time of Day display appears.

Reset the heart rate monitor. The RESET button is a small recessed

the latest exercise file will be saved.
1. Press the RESET button with a pen tip. Display will become full
of digits.
If you don’t press any button after reset, within one minute
the wrist receiver will automatically go to the time of day

...the battery of the wrist receiver must be replaced?
We recommend having all service done by an authorized Polar
Service Center. This is especially necessary to ensure the guarantee
remains valid and is not affected by incorrect repair procedures
done by an unauthorized agent. Polar Service will test your wrist
receiver for water resistance after battery replacement and make
a full periodic check of the complete Polar heart rate monitor.
However, if you wish to change the battery yourself, please
follow the instructions in the Care and Maintenance section of
this manual.
