5. CARE AND MAINTENANCE
Your Polar heart rate monitor is a high-tech instrument and should
be treated with care. The suggestions below will help you fulfi ll the
guarantee obligations.
Store your heart rate monitor in a cool, 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.
Service
During the two-year guarantee/warranty period, we recommend
that your product is serviced by an authorized Polar Service Center
only. The warranty does not cover damage or consequential damage
caused by any service not authorized by Polar Electro.
Taking Care of Your Polar Heart Rate Monitor
• Keep your unit clean. Clean it with a mild soap and water
solution. Dry it carefully with a soft towel. Never use alcohol or
any abrasive material such as steel wool or cleaning chemicals.
• Never store the transmitter when it is wet. Sweat and moisture
can keep its electrodes wet and the transmitter activated,
which shorten the lifespan of the battery.
• Keep your 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 heart rate monitor to direct sunlight for
extended periods, eg. by leaving it in a car.
• 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.
Mishandling may damage the electrodes.
Transmitter Battery
The estimated average battery lifespan of the transmitter is
2500 hours of use. If you suspect that the transmitter battery has
discharged, contact your authorized Polar Service Center for a
replacement transmitter. Polar recycles used transmitters.
Wrist Unit Battery
The estimated average battery lifespan of the wrist unit is two years
with normal use (1h/day, 7 days a week). The
indicates a low
battery and that the battery should be replaced. Please note that
excessive use of the alarm signal
and the backlight (FS2/FS3) will
drain the battery more rapidly. Do not open the wrist unit yourself.
To ensure the water resistance properties and the use of qualifi ed
components, the wrist unit battery should be replaced by an authorized
Polar Service Center only. At the same time, a full periodic check of
the Polar heart rate monitor will be done.
Note:
• In cold conditions, the low battery indicator may appear,
but the indicator is deactivated when you return to a normal
temperature.
• Water resistance cannot be guaranteed after unauthorized
service.
•
The sounds and the backlight FS2/FS3 are disabled when
the battery is low, in order to optimize the battery lifespan.
