Battery
Avoid opening the sealed battery cover during the guarantee period. We recommend that you have the battery replaced by an authorized Polar Service Center. They will test your activity watch for water resistance after battery replacement, and will make a full periodic check.
However, if you decide to change the battery yourself anyway, please note the following:
•The low battery indicator is displayed when
•Excessive use of the backlight and altimeter drain the battery more rapidly.
•In cold conditions, the low battery indicator may appear, but will disappear when the temperature rises.
•The backlight and sound are automatically turned off when the low battery indicator is displayed. Any alarms set prior to the appearance of the low battery indicator will remain active.
Open the battery cover only when the battery needs changing. We recommend that you change the sealing ring of the battery cover every time you change the battery. Additional sealing rings are available at authorized Polar Service Centers only.
