When the battery is critically low, Recording ended is shown. M430 stops the training recording and
saves the training data.
When the display is blank, the battery is empty and M430 has gone to sleep mode. Charge your M430. If the
battery is totally drained, it may take a while for the charging animation to appear on the display.

CARING FOR YOUR M430

Like any electronic device, the Polar M430 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 M430 CLEAN

Wash the M430 under running water with a mild soap and water solution after each training session. Wipe it
dry with a soft towel.
Keep the M430's USB port and charging cable clean to ensure smooth charging and syncing.
Before charging, make sure there's no moisture, hair, dust or dirt on the M430's USB port or charging cable.
Gently wipe off any dirt and blow off any dust. You can use a toothpick if needed. Do not use any sharp tools
for cleaning to avoid scratching.
Keep the USB port clean to effectively protect your M430 from oxidation and other possible damage caused
by dirt and salt water (e.g. sweat or sea water). The best way to keep the USB port clean is to rinse it after
each training session with lukewarm tap water. The USB port is water resistant and you can rinse it under
running water without damaging the electronic components. Do not charge the M430 when the USB port is
wet or sweaty.

TAKE GOOD CARE OF THE OPTICAL HEART RATE SENSOR

Keep the optical sensor area on the back cover scratch-free. Scratches and dirt will reduce the performance
of the wrist-based heart rate measurement.

STORING

Keep your training device in a cool and dry place. Do not keep it 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.
