CARE AND MAINTENANCE
Your Polar Heart Rate Monitor is a high-tech instrument of
superior design and workmanship and should be treated
with care. The suggestions below will help you fulfill the
warranty obligations and enjoy this product for many years
to come.
TAKING CARE OF YOUR POLAR
HEART RATE MONITOR
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.
