POLAR FT60 - Manual (Page 41)

Troubleshooting
If you don't know where you are in the menu, press and
hold
BACK until the time of day is displayed.
If there are no reactions to any buttons or the wrist unit
displays unusual readings, reset the wrist unit by pressing
four buttons (UP, DOWN, BACK and LIGHT)
simultaneously for four seconds. All other settings but
time and date are saved.
If the heart rate reading becomes erratic, extremely high
or shows nil (00), make sure that there are no other heart
rate transmitters within 1 m/3 ft and that the transmitter
strap/the textile electrodes fit snugly and are moistened,
clean and undamaged.
If the heart rate measurement does not work with the
sports apparel, try measuring using the strap. If it works,
the problem is most probably in the apparel. Please
contact the apparel retailer/manufacturer.
Strong electromagnetic signals can cause erratic readings.
Electromagnetic disturbances may occur near high-voltage
power lines, traffic lights, overhead lines of electric
railways, electric bus lines or trams, televisions, car
motors, bike computers, some motor driven training
equipment, cellular phones, or at electric security gates.
To avoid erratic readings, move away from possible
sources of disturbance.
If the abnormal reading continues despite moving away
from the source of disturbance, slow down 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.
A cardiac event may have altered your ECG waveform. In
this case, consult your physician.
If heart rate measurement does not work despite the
actions mentioned previously, the battery of your
transmitter may be empty.
