you walk through electric security gates.
CROSSTALK
The non-coded Polar wrist receiver in mode of operation
picks up transmitter signals within 3 feet/1 meter.
Therefore, make sure no other transmitter is within that
range. Signals from more than one transmitter picked up
simultaneously can cause an incorrect readout.
EXERCISE EQUIPMENT
Several pieces of exercise equipment with electronic or
electrical components such as LED displays, motors and
electrical brakes may cause interfering stray signals. To try
to tackle these problems, relocate the Polar wrist receiver
as follows:
1. Remove the transmitter from your chest and use the
exercise equipment as you would normally.
2. Move the wrist receiver around until you find an area in
which it displays no stray reading or flashing of the heart
symbol. Interference is often worst right in front of the
display panel of the equipment, while the left or right
side of the display is relatively free of disturbance.
3. Put the transmitter back on the chest and keep the wrist
receiver in this interference-free area as far as it is
possible.
4. If the Polar Heart Rate Monitor still does not work with
the exercise equipment, this piece of equipment may be
electrically too noisy for wireless heart rate
measurement.
