The operating time varies depending on
operating conditions (e.g. high or low
temperatures) and battery aging. The operating
time is significantly reduced in temperatures
well below freezing. Wearing RC3 GPS under
your overcoat helps to keep it warmer and to
increase the operating time.
To learn when to recharge the battery, see the

Heart Rate Sensor
The Polar heart rate sensor has a user
changeable battery.
When changing the battery, make sure the
sealing ring is not damaged, in which case you
should replace it with a new one to ensure the
water resistance of the connector.
You can purchase the sealing ring/battery kits at
well-equipped Polar retailers and authorized
Polar Services. In the USA and Canada, the
additional sealing rings are available at
authorized Polar Service Centers. In the USA
the sealing ring/battery kits are also available at
www.shoppolar.com.
When handling a new, fully charged battery,
avoid clasp-like contact, i.e. simultaneous from
both sides, with metal or electrically conducting
tools, like tweezers. This may short-circuit the
battery causing it to discharge more rapidly.
Typically, short circuiting does not damage the
battery, but it may decrease the capacity and
lifetime of the battery.
