Polar Wrist Unit
The estimated average battery life of the Polar wrist unit is
20 months in normal use (1 h / day, 7 days a week). Note also that
excessive use of the backlight and the alarm signals will use the
battery more rapidly.
Do not open the Polar wrist unit yourself. To ensure the water
resistance properties and the use of qualified components, the wrist
unit 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.
