KEEP YOUR WATCH CLEAN
Wash the watch under running water with a mild soap and water solution after each training session.
Wipe it dry with a soft towel.
Keep the charging contacts of your watch and cable clean to ensure smooth charging and
syncing.
Before charging, please make sure there’s no moisture, dust or dirt on the charging contacts of your
watch and cable. Gently wipe off any dirt or moisture. Do not charge the watch when it’s wet.
Keep the charging contacts of your watch clean to effectively protect your watch from oxidation and
other possible damage caused by dirt and salt water (e.g. sweat or sea water). The best way to keep the
charging contacts clean is to rinse the watch after each training session with lukewarm tap water. The
watch is water resistant and you can rinse it under running water without damaging the electronic
components. Do not charge the watch when it's 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.
Do not leave the device in extreme cold (below –10 °C/14 °F) and heat (above 50 °C/120 °F)
or under direct sunlight.
SERVICE
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.
