Maintenance of Your M450/M460
Like any electronic device, the Polar M450/M460 should be kept clean and treated with care. The instructions below will help you fulfill the guarantee obligations, keep the device in peak condition and avoid any issues in charging or syncing.
Keep your training device clean. Use a damp paper towel to wipe dirt from the training device. To maintain the water resistance, do not wash the training device with a pressure washer. Do not immerse the training device in water. Never use alcohol or any abrasive material such as steel wool or cleaning chemicals.
The USB cable must be connected carefully to avoid damaging the device's USB port.
After each time of using the USB port of the training device, check visually that there is no hair, dust or other dirt on the sealing surface area of the lid/back case. Gently wipe to remove any dirt. A toothpick can be used to remove dirt from the connector cavity. Don't use any sharp tools for cleaning to avoid scratching.
Keep your training device in a cool and dry place. Do not keep it in a damp environment, in non-breathable material nor with conductive material. Do not expose the training device to direct sunlight for extended periods.
Do not leave the device in extreme cold (below –10 °C/14 °F) and heat (above 50 °C/120 °F) or under direct sunlight.
The operating temperature of M450 is -10 °C to +50 °C / 14 °F to 122 °F. Using or storing your M450/M460 in an environment where temperature is not within this temperature range may permanently damage the battery capacity - especially if the temperature is higher.
Store the device partially or fully charged. The battery slowly loses its charge when it is stored. If you are going to store the device for several months, it is recommended to recharge it after a few months. This will prolong the battery life.
Detach the connector from the strap after every use and dry the connector with a soft towel. Clean the connector with a mild soap and water solution when needed. Never use alcohol or any abrasive material (e.g. steel wool or cleaning chemicals).
Rinse the strap under running water after every use and hang to dry. Clean the strap gently with a mild soap and water solution when needed. Do not use moisturizing soaps, because they can leave residue on the strap. Do not soak, iron, dry clean or bleach the strap. Do not stretch the strap or bend the electrode areas sharply.
Check the washing instructions on the label of the strap.
Dry and store the heart rate sensor strap and the connector separately to maximize the battery lifetime. Keep the heart rate sensor in a cool and dry place. To prevent snap oxidation, do not store the heart rate sensor wet in non-breathable material. Do not expose the heart rate sensor to direct sunlight for extended periods.
During the two-year guarantee/warranty period we recommend that you have service done by an authorized Polar Service Center only. The warranty does not cover damage or consequential damage caused by service not authorized by Polar Electro. For further information, see Limited International Polar Guarantee.
