Customer Care Charter for detailed instructions.
Polar recycles used transmitters.
POLAR M71 ti RECEIVER
The estimated average battery life of the Polar M71 ti receiver is 1 year in normal use (2h/day, 7 days a week). However, because the battery is inserted at the factory, the actual life of your first battery once in your possession may be less than the estimated battery life. Note also that excessive use of the backlight and 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 a person authorized by Polar Electro Inc. At the same time a full periodic check of the Polar Heart Rate
Monitor will be done.
