9. FREQUENTLY ASKED QUESTIONS
What should I do if...
...I don’t know where I am in the menu?
Press and hold the RED button until the time of day is displayed.
...there is no heart rate reading (00/ --) or the heart symbol
flashes irregularly?
1. Make sure the electrodes of the transmitter are wet and that
the transmitter is worn as instructed. The strap must be
snug enough.
2. Make sure the transmitter is clean.
3. Make sure no sources of electromagnetic radiation are in
close vicinity to the Polar wrist unit, such as TV sets, cell
phones, CRT monitors etc.
4. Make sure no other heart rate transmitter is within the
reception range (3 feet / 1 meter).
5. Cardiac arrhythmia may cause irregular readings, or a
cardiac event may have altered your ECG waveform. In these
cases, consult your physician.
...there is interference between the heart rate monitors of two
students?
The two students may have exactly the same heart rate
transmission code. Separate the two by at least 3 feet / 1 meter
and have them continue exercising as before.
Or
Separate the students and have at least one of them stop the
recording and remove his or her transmitter for 30 seconds.
Put the transmitter back on and restart the recording. This will
cause the wrist unit to search for a new code.
Note: To minimize interference between monitors, have your
students stand at least 3 feet / 1 meter apart when they start
their recordings. This allows the wrist unit to lock onto a single
heart rate signal and transmission code.
...heart rate reading becomes erratic or extremely high?
Strong electromagnetic signals can cause erratic readings. Move
away from possible sources of disturbance such as high-voltage
power lines, traffic lights, overhead lines of electric railways or
trams, car motors, bike computers, some motor-driven exercise
equipment (like fitness testers) or cell phones.
If moving away does not help and the heart rate reading remains
erratic, slow down speed and check the pulse manually. If it
corresponds to the high reading on the display, it may be a sign
of cardiac arrhythmia. Most cases of arrhythmia are not serious,
but consult a doctor nevertheless.
...the display is blank?
The Polar E40 heart rate monitor is in battery saving mode
when it is dispatched from the factory. To activate it, press any
button twice. For further information, see chapter 1.3 Before
Using the Wrist Unit.
...the display is fading?
The first sign of an expired battery is the low battery symbol
.
Have the batteries checked. For more information, see chapter
7 Care and Maintenance. After a battery replacement, you only
need to set the time of day and date in the Basic Settings.
Then press and hold the RED button to return to the Time of
Day display.
