8. FREQUENTLY ASKED QUESTIONS
What should I do if…
…if I do not know where I am in the menu?
Press and hold the Stop button until the time of day is displayed.
…there are no reactions to any buttons?
Reset the wrist unit by pressing the four side buttons simultane-
ously for two seconds. Set the time and date in the Basic Setting
after the reset. Other settings are saved.
…the heart rate reading becomes erratic or extremely high?
Strong electromagnetic signals can cause erratic readings. So move
away from possible sources of disturbance such as high-voltage
power lines, traffi c lights, overhead lines of electric railways or
trams, car motors, bike computers, some motor-driven exercise
equipment (like fi tness testers) or cell phones.
If moving away does not help and the heart rate reading remains
erratic, slow down your speed and check your pulse manually. If you
feel it corresponds to the high reading on the display, you may be
experiencing cardiac arrhythmia. Most cases of arrhythmia are not
serious, but consult your doctor nevertheless.
…the heart symbol fl ashes irregularly?
• Check that your wrist unit is not further than 1 m/3 ft from the
transmitter.
• Check that the transmitter has not become loose during
exercise.
• Make sure that the electrodes of the transmitter are moistened.
…the low battery symbol
appears?
Usually the fi rst sign of an expired battery is the low battery
indicator on the display. For further information, see page 49.
Note: Due to cold conditions the low battery indicator may appear,
but the indicator disappears when you return to a normal
temperature.
…the display is blank?
The running computer is in battery saving mode when it is
dispatched from the factory. To activate it, press the Red button
twice. The Basic Settings starts. For further information, see page 8.
Alternatively the battery may be dead (see the next question for
further instructions).
…the battery of the wrist unit must be replaced?
We recommend having all service done by an authorized Polar
Service Center. This is especially necessary to ensure that the
guarantee remains valid and is not affected by incorrect repair
procedures performed by an unauthorized agent. Polar Service will
test your wrist unit for water resistance after battery replacement
and make a full periodic check of the complete running computer
set.
• Make sure that there is no other heart rate transmitter within
1 m/3 ft.
• Cardiac arrhythmia may cause irregular readings. In this case,
consult your physician.
…there is no heart rate reading (- -)?
• Check that the electrodes of the transmitter are moistened and
that you are wearing it as instructed.
• Make sure the transmitter is clean.
• Check that you are not near high voltage power lines,
televisions, cell phones or other sources of electromagnetic
interference.
Also make sure that you are not near (1 m/3 ft) other heart rate
monitor users, when starting you exercise recording.
• A cardiac event may have altered your ECG waveform. In this
case, consult your physician.
…another person with a running computer or a heart rate moni-
tor is causing interference?
Move away from that person and continue your exercise normally.
Alternatively,
1. Take the transmitter off your chest for 30 seconds. Stay away
from the person with the other device.
2. Put the transmitter back on and bring the wrist unit up to your
chest near the transmitter’s Polar logo. The wrist unit will start
looking for a heart rate signal again. Continue your exercise
normally.
