The Batteries
Should your HRM need battery replacement or
service we strongly recommend it be done by
a POLAR authorized center only in order to
make sure that the unit is adequately tested for
water resistance. This is particularly important
when the unit is used under heavy sweat
conditions or for swimming. If you service the
unit yourself, you will void the warranty. The
rubber gasket that insures water resistance will
deteriorate over time and needs to be replaced
every time the seal is broken.
To conserve battery life, the Wrist Monitor is
programmed to automatically return to the TIME
selection after ten minutes when no buttons have
been pushed and no pulse has been received
from the Transmitter.
The Wrist Monitor
Water Resistance: Due to the many variables
involved, water resistance cannot be regarded as
a permanent characteristic of any Monitor. We do
recommend that the Wrist Monitor is tested for
water resistance every l-2 years (depending on
use) to check for natural deterioration of
lubricants and seals as well as possible damage
to glass and case which may impair the optimum
water resistance characteristics. This is particularly
important if you are using your POLAR Wrist
Monitor for swimming. It is also important to be
careful not to operate the buttons while under
water, as the pressure can cause the Wrist
Monitor to leak.
The Transmitter
The Transmitter automatically activates when it is
attached to your chest and will shut off when it
is removed from your skin. However sweat and
moisture can keep it activated so it is important
to wipe off and dry the Transmitter when taking it
off. To maximize the life of the Transmitter it is
also important to clean it with mild soap and
water regularly to remove any buildup that could
weaken it’s strength. Be sure not to use any
abrasives or chemicals such as steel wool or
alcohol, they can cause permanent damage to
the electrodes.
The transmitter battery is not replaceable,
however it is estimated to last 2500 hours of use
when handled according to this care and
maintenance instruction. Do not throw out your
old Transmitter, it is a recycleable item. Return it
to POLAR when purchasing new.
Important: Do not stretch or bend the electrode
strips of the Transmitter, especially when storing
it, this can damage their conductivity.
