Excessive use of the backlight drains the Training System’s battery more rapidly. In cold
conditions, the low battery indicator may appear, and disappear again when you return to a
warmer environment. To ensure the maximum lifespan of the battery cover, open it only when
changing battery. When changing the battery, make sure the sealing ring is not damaged, in
which case you should replace it with a new one. Battery kits with sealing rings are available
at well-equipped Polar retailers and authorized Polar Service Centers. In the USA and
Canada, sealing rings are available at authorized Polar Service Centers only.
Keep batteries away from children. If swallowed, contact a doctor immediately. Batteries
should be properly disposed of according to local regulations.
