Taking Care of Your A370
Like any electronic device, Polar A370 should be treated with care. The suggestions below will help you fulfill guarantee obligations and enjoy this product for many years to come.
The USB cable must be connected carefully to avoid damaging the device's USB port.
Don't charge the device when its USB port is wet. Let the USB port dry up by leaving the port cover open for a while before charging. This way you'll ensure smooth charging and syncing.
Keep your training device clean.
- We recommend that you wash the device and the silicone wristband after each training session under running water with a mild soap and water solution. Please remove the device from the wristband and wash them separately. Wipe them dry with a soft towel.
It is essential that you wash the device and the wristband if you wear them in a swimming pool where chlorine is used for keeping the pool clean.
- If you don't wear the device 24/7, wipe off any moisture before storing it. Don't store in non-breathable material or in a damp environment, e.g. plastic bag or damp gym bag.
- Wipe it dry with a soft towel when needed. 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. Never use alcohol or any abrasive material such as steel wool or cleaning chemicals.
- When you connect your A370 to a computer or a charger, check that there is no moisture, hair, dust or dirt on the A370's USB connector. Gently wipe off any dirt or moisture. Don't use any sharp tools for cleaning to avoid scratching.
Operating temperatures are -10 °C to +50 °C / +14 °F to +122 °F.
Keep your training device in a cool and dry place. Do not keep them in a damp environment, in non-breathable material (a plastic bag or a sports bag) nor with conductive material (a wet towel). Do not expose the training device to direct sunlight for extended periods, such as by leaving it in a car or mounted on the bike mount.
It is recommended to store the training device partially or fully charged. The battery slowly loses its charge when it is stored. If you are going to store the training device for several months, it is recommended to recharge it after a few months. This will prolong the battery lifetime.
Dry and store the strap and the connector separately to maximize the heart rate sensor 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-breathing material, such as a sports bag. Do not expose the heart rate sensor to direct sunlight for extended periods.
