What if the heart symbol flashes ir-
regularly?
Check to see if your Wrist Receiver is outside
the 3 ft/1 meter range of heart rate transmission
from the Transmitter.
Make sure the elastic strap has not loosened
during exercise.
If you are wearing the Polar Transmitter over a
shirt, make sure there is moisture to make the
needed contact with the electrodes.
Check your surroundings. If you are in an
electromagnetic field created by other
equipment (such as a monitor or television set),
move away. If you are near another athlete
using a heart rate monitor, move away.
What do I do if the Monitor goes blank?
Have the batteries checked by authorised Polar
service personnel. Contact your distributor/
dealer for details.
SERVICE
Should your Polar Protrainer NV HRM need
servicing, please, follow the instructions below:
• Carefully pack the Polar Protrainer NV HRM
Wrist Receiver and the Transmitter in a
shipping carton so it will not be damaged
(original package will suit this purpose well).

This is called Global Clear. When a three line
display appears, press
STORE/LAP button,
and a time display of 10 o’clock will appear.
Start the programming cycle here with the
TIME
setting.
Note: Global Clear clears the memory totally.
The Global Clear setting is also very useful, if
for any reason, you want to start from scratch to
enter information into the Wrist Receiver’s
memory.
What if there is no heart rate reading?
Check to see that the elastic strap is tight
enough. The strap should be adjusted with the
electrodes flat against your skin. You may have
to move the Polar Transmitter leftward to find
the best position. Make sure that the position of
the Polar logo is correct.
Check to make sure that the electrode strips
are thoroughly moistened. The Transmitter will
not function properly without moisture to make
good electrical contact.
Accumulated sweat and dirt may interfere with
clear reception of the signal from the skin to the
Transmitter. Check to see if your Transmitter
needs cleaning.
