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.

•Keep the air pressure channels (three openings on the wrist receiver backcover) clean to make sure that the altitude and temperature measurements work. Do not insert any objects into the openings.

•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 distributor/ dealer for a transmitter replacement. Polar recycles used transmitters. See your Customer Care Charter for detailed instructions.

Wrist receiver

The estimated average battery life of the 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 Speed Sensor

The estimated average battery life of the 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:
