... THE BATTERY OF THE WRIST RECEIVER MUST BE
REPLACED?
We recommend having all service done by an authorised
Polar Service Centre. This is especially necessary to ensure the warranty remains valid and is not affected by incorrect repair procedures done by an unauthorised 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.
