ENGLISH
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 exercise equipment, cellular
phones, or at electric security gates. To avoid
erratic readings, move away from possible sources
of disturbance.
Exercise equipment with electronic components
may cause interfering stray signals. To tackle
these problems, try the following:
1. Remove the transmitter from your chest and
use the exercise equipment as you would
normally.
2. Move the wrist unit around until you fi nd an
area in which it displays no stray reading or
does not fl ash 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 your chest and
keep the wrist unit in this interference-free area
as much as possible.

for wireless heart rate measurement.
