Polar T31C Transmitter Maintenance

With good care your T31C heart rate sensor last longer. Dirt impairs the elasticity and functioning of the heart rate sensor.

Wash the heart rate sensor regularly after use. T31C heart rate sensor should be washed with a mild soap and water solution. After washing, dry the heart rate sensor carefully with a soft towel.

If the electrodes appear discolored, you may use a gentle brush. Do not use any alcohol or a solvent based detergent.

Rinse the elastic strap with water after every use and wash it regularly in a washing machine at 40ºC/104ºF. This ensures reliable measurement and maximizes the life span of the heart rate sensor. Use a washing pouch. Do not soak, spin-dry, iron, dry clean or bleach the strap. Do not use detergent with bleach or fabric softener. Hang the elastic strap up to dry.

Wash the elastic strap in a washing machine before long-term storage, and always after use in pool water with high chlorine content. Never put the heart rate sensor in the washing machine or drier!

Never store the heart rate sensor wet, in a damp environment or in any kind of non-breathing material, such as a plastic bag or a sports bag. Sweat and moisture may keep the electrodes wet and the heart rate sensor activated. This will shorten the battery life. Keep in a cool and dry place.

Do not bend or stretch the heart rate sensor. This may damage the electrodes.
