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.
