Precautions
Interference During Exercise
Electromagnetic Interference and Exercise
Equipment. Disturbance 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 when you walk through electric security
gates. Microwave ovens, computers and WLAN
base stations may also cause interference when
exercising with RS800. To avoid erratic readings,
move away from possible sources of disturbance.
Exercise equipment with electronic or electrical
components such as LED displays, motors and
electrical brakes may cause interfering stray
signals. To solve these problems, try the following:
1.
Remove the transmitter from your chest and
use the exercise equipment as you would
normally.
2.
Move the running computer around until you
find an area in which it displays no stray
reading or does not flash the heart symbol.
Interference is often worst directly 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 running computer in this
interference-free area as much as possible.
If the running computer still does not work with
the exercise equipment, it may be electrically too
noisy for wireless heart rate measurement.
