• Wash the transmitter regularly after use with a mild soap
and water solution. Dry it carefully after washing.
• Never store the transmitter wet. Sweat and moisture can
keep its electrodes wet and the transmitter activated,
which shortens the battery life.
• Store your Polar Heart Rate Monitor in a cool and dry
place. Do not store it in any kind of non-breathing
material, such as a plastic bag or a sports bag if it is wet.
• Do not bend or stretch the transmitter. This may damage
the electrodes.
• Don’t dry the transmitter in any other way than with a
towel. Hard-handed handling may damage the
electrodes.
• Keep your Polar Heart Rate Monitor out of extreme cold
(below 14 ºF / -10 ºC) and heat (above 122 ºF / 50 ºC).
• Do not expose the Polar Heart Rate Monitor to direct
sunlight for extended periods, such as by leaving it in a
car.
