7. 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 fulfill the guarantee obligations and enjoy the product for many years to come.

Taking Care of Your Polar Heart Rate Monitor

•Clean the transmitter regularly after use with a mild soap and water solution. Dry it carefully with a soft towel. Keep the wrist unit clean and wipe off any moisture. Never use alcohol or any abrasive material such as steel wool or cleaning chemicals.

•Do not dry the transmitter in any other way than with a towel. Mishandling may damage the electrodes.

•Never store the transmitter wet. Sweat and moisture can keep its electrodes wet and the transmitter activated, which shortens the battery life span.

•Store your 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.

•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, such as by leaving it in a car.

Service

During the two-year guarantee/warranty period we recommend that you have service done by an authorised Polar Service Center. The warranty does not cover damage or consequential damage caused by service not authorised by Polar Electro.

Transmitter Batteries

The estimated average battery life span of the transmitter is 2500 hours of use. If you suspect that the transmitter battery has run out, contact your authorized Polar Service Center for a replacement transmitter. Polar recycles used transmitters.

Wrist Unit Batteries

The estimated average battery life span of the wrist unit is two years in normal use (including 1h/day, 7 days a week of exercising). Please note that excessive use of the alarm signals drain the battery more rapidly.

The battery symbol indicates that the battery should be replaced.

Note:

•If you have set the alarm before the symbol is displayed, the alarm will still activate until the battery runs out.

If you try to reset the alarm the wrist unit displays Battery Low. You cannot reset the alarm until the battery is changed.

•In cold conditions the low battery indicator may appear, but the indicator is deactivated when you return to a normal temperature.

•Do not open the wrist unit yourself. To ensure the water resistance properties and the use of authorized 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.
