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 guarantee
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 14 ° F to 122 ° F/ -10 ° C to
50 ° C.
• Do not expose the Polar heart rate monitor to direct sunlight
for extended periods, such as by leaving it in a car.
• Do not immerse the speed sensor in water.
• Avoid hard hits to the speed sensor as these may cause
damage.
Batteries
Transmitter
The estimated average battery life of the transmitter is 2500
hours of use. Contact your authorized Polar service center for a
replacement transmitter. Polar recycles used transmitters. See
your Customer Care Charter for detailed instructions.
Wrist Receiver
The estimated average battery life of the wrist receiver is 1,5
years in normal use (1h/ day, 7 days a week). Note also that
excessive use of 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 authorized Polar Service Center. At the same time a full
periodic check of the Polar heart rate monitor will be done.
Service
Should your Polar heart rate monitor need service, see Customer
Care Charter to contact an authorized Polar Service Center.
Water resistance cannot be guaranteed after unauthorized
service.
