Like any electronic device, the Polar M450 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.
M450
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. Do not use
any sharp tools or equipment for cleaning, which could cause scratches to the plastic parts.
Not suitable for bathing or swimming. Protected against wash splashes and raindrops. Do not
immerse the training device in water. Using the training device in excessive rainfall may cause interference
on GPS reception.
Do not leave the device in extreme cold (below –10 °C/14 °F) and heat (above 50 °C/120 °F)
or under direct sunlight.
