TAKE GOOD CARE OF THE OPTICAL HEART RATE SENSOR
Keep the optical sensor area scratch-free. Scratches and dirt will reduce the performance of optical 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. 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.

PRECAUTIONS
The Polar OH1 is designed to measure heart rate. No other use is intended or implied.
The training device should not be used for obtaining environmental measurements that require professional
or industrial precision.
We recommend that once in a while you wash the device and the armband to avoid any skin problems from a
dirty armband.
INTERFERENCE DURING TRAINING
Electromagnetic Interference and Training Equipment
Disturbance may occur near electrical devices. Also WLAN base stations may cause interference when
training with the training device. To avoid erratic reading or misbehavior, move away from possible sources of
disturbance.
