Safety note: Disconnect the device from the mains before performing any
maintenance work. Wear appropriate protective clothing when working on the
device.
Problem

compatible?

displayed irregularly.

Solution
• Ensure sufficient and good
lighting in the room. Make sure
the light does not reflect from the
display.
• Most commercially available
chest straps are suitable. Make
sure the chest strap is not
encoded and transmits with a
frequency of 5 kHz.
• Note: If there is no display while
wearing a chest strap, check the
batteries of the chest strap. (A
heart rate monitor might work
with almost empty batteries, but
the receiver of the computer
requires higher signal strength.)
• Measuring the pulse rate
using hand pulse sensors is
naturally not as precise as
measuring using a chest strap.
It depends on the skin structure
(thickness), sweat, etc. The
hand pulse sensors (or the
device) can become statically
charged during workout due to
friction, disrupting the heart rate
measurement as a result.
TIP: Placing a special anti-
static mat underneath can help
prevent static charge.
• Furthermore, the following
factors can affect the pulse rate
measurement (both via hand
pulse sensors or chest strap):
Mobile phones, Tvs, radios,
power lines, transmission
towers, electrified railway lines,
etc. Make sure the surrounding
of the device is free from such
interfering sources.
