Batteries
Polar T61 transmitter
The estimated average battery life of the Polar T61 transmitter is 2500
hours of use. Contact your distributor/ dealer for a transmitter
replacement. Polar recycles used transmitters. See your Customer Care
Charter for detailed instructions.
Polar S710 wrist receiver
The estimated average battery life of the Polar S710 wrist receiver is 2
years in normal use (2h/ day, 7 days a week). Note also that excessive use
of the backlight and the alarm signals will use the battery more rapidly.
Do not open the Polar wrist receiver yourself. To ensure the water
resistance properties and the use of qualified components, the wrist
receiver battery should be replaced only by an authorised Polar Service
Centre. At the same time a full periodic check of the Polar heart rate
monitor will be done.
Battery Replacement for Polar Speed Sensor
The estimated average battery life of the Polar Speed Sensor is 2500
hours of use. We highly recommend you send the speed sensor to an
authorised Polar Service Centre for battery replacement, where the unit
is water-resistant tested after the battery has been replaced. However, if
you prefer changing the battery yourself, please follow these
instructions carefully:

G. CARE AND
MAINTENANCE
Your Polar heart rate monitor is a high-tech instrument of superior
design and workmanship and should be treated with care. The
suggestions below will help you fulfill the warranty obligations
and enjoy this product for many years to come.
Taking care of your Polar heart rate monitor
• Wash the transmitter regularly after use with a mild soap and water
solution. Dry it carefully after washing with soft towel.
• Never store the transmitter wet. Sweat and moisture can keep its electrodes
wet and the transmitter activated, which shortens the battery life.
• Store your Polar heart rate monitor in a cool and dry place. Do not store it
in any kind of non-breathing material, such as a plastic bag or a sports bag
if it is wet.
• Do not bend or stretch the transmitter. This may damage the electrodes.
• Do not dry the transmitter in any other way than with a towel. Hard-
handed handling may damage the electrodes.
• Keep your Polar heart rate monitor out of extreme cold and heat.
The operating temperature is -10 ºC to 50 ºC/ 14 ºF to 122 ºF.
• Do not expose the Polar heart rate monitor to direct sunlight for extended
periods, such as by leaving it in a car.
