Batteries
Transmitter
The estimated average battery life of the transmitter is 2500 hours of use. Contact your authorized Polar service center for a replacement transmitter. Polar recycles used transmitters. See your Customer Care Charter for detailed instructions.
Wrist Receiver
The estimated average battery life of the wrist receiver is 1,5 years in normal use (1h/ day, 7 days a week). Note also that excessive use of 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 authorized Polar Service Center. At the same time a full periodic check of the Polar heart rate monitor will be done.
Service
Should your Polar heart rate monitor need service, see Customer Care Charter to contact an authorized Polar Service Center.
Water resistance cannot be guaranteed after unauthorized service.
