The CS100 cycling computer has a user changeable
battery. To change the battery yourself, please follow the
instructions carefully.

cover, open it only when you need to change the battery.

10-15% of the cycling computer battery capacity is left and
the battery should be replaced. The backlight and cycling
computer sounds are automatically deactivated when is
displayed.
• Excessive use of the backlight drains the cycling computer’s
battery more rapidly.
• In cold conditions the low battery indicator may appear,
but the indicator disappears when you return to warmer
temperature.

When changing the battery, make sure the sealing ring is
not damaged, in which case you should replace it with a
new one. You can purchase the sealing ring/battery kits at
well-equipped Polar retailers and authorized Polar Services.
