and clean the Transmitter when
needed. The Transmitter and the elastic strap
can be washed with a mild soap and water
solution. However, never use alcohol or any
abrasives such as steel wool or cleaning
chemicals. They will cause permanent damage
to the electrodes.
Note: Do not stretch or bend the electrode strips
of the Polar Transmitter, especially when storing
it (more than is needed to store it in the original
container), because this could damage their
conductivity.
BATTERIES
In order to ensure the water resistance of the
HRM, the batteries of the Wrist Receiver
should only be replaced by a person
authorised by Polar Electro Oy. For
details, contact your dealer or distributor.
To conserve battery life, the Wrist Receiver is
programmed to automatically return to the
TIME
selection after ten minutes, when no buttons
have been pushed and no heart rate has been
received from the Transmitter. In
MEASURE
mode, the receiver circuitry voltage is cut off
within 10 minutes, if no heart rate has been
received. As an indication of this the lowest line
of digits will show --, but the stopwatch keeps
on going to facilitate time measurement without
heart rate information.
6. Press the
STORE/LAP button repeat-
edly to cycle through all the recorded split/lap
times and heart rates.
7. Once the first lap/split time appears on
display again, press SET/START/STOP
button to return to step 1 on this list.
8. To leave the selection, press the
SELECT
button (twice to go to TIME mode).
CARE AND
MAINTENANCE
WRIST RECEIVER
The rubber gasket seals that ensure water
resistance on the Wrist Receiver will deteriorate
over time. It is recommended that these seals
are replaced after two years of use. This is
particularly important if you are using your Polar
Protrainer NV HRM for swimming.
POLAR TRANSMITTER AND
THE ELASTIC STRAP
The Polar Transmitter is in an active mode only
when it is attached to the chest for measure-
ment. It should not be activated when it is not
worn. However, sweat and other moisture on
the Transmitter can keep it running after it is
removed from the body. Therefore, to avoid
wasting battery energy, you should wipe dry
