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.

T A K I N G C A R E O F Y O U R P O L A R H E A R T R A T E M O N I T O R

Wash the transmitter regularly after use with a mild soap and water solution. Dry it carefully after washing.

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.

Don’t 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 (below 14 ºF / -10 ºC) and heat (above 122 ºF / 50 ºC).

Do not expose the Polar heart rate monitor to direct sunlight for extended periods, such as by leaving it in a car.

POLAR TRANSMITTER

The estimated average battery life of the transmitter is 2500 hours of use. Contact your distributor/ dealer for a transmitter replacement. Polar recycles used transmitters.

POLAR WRIST RECEIVER

The estimated average battery life of the Polar wrist receiver is 1 year 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 authorized Polar Service Center. At the same time a full periodic check of the Polar heart rate monitor will be done.

S E R V I C E

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.
