CARING FOR YOUR M400
Like any electronic device, the Polar M400 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 char-
ging or syncing.
M400
Keep the device clean
l You can wash the device with a mild soap and water solution under running water. Do not use alcohol
or any abrasive material such as steel wool or cleaning chemicals.
l 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.
Keep the device's USB port clean to ensure fluent charging and syncing
l Open the USB port cover and rinse the USB port with lukewarm water after each training session. After
rinsing, leave the cover open for a while to let the USB port dry. Do not charge the device when the
USB port is wet.
l Keep the USB port cover closed when you are not charging or syncing the device. Close it also after
you have rinsed the USB port and it has dried. When using the USB port, check that there is no mois-
ture, hair, dust or dirt on the sealing surface area. Gently wipe off any dirt. A toothpick can be used to
remove hair, dust or other dirt from the connector cavity. Don't use any sharp tools for cleaning to avoid
scratching.
Do not leave the device in extreme cold (below –10 °C/14 °F) and heat (above 50 °C/120 °F) or under
direct sunlight.
