between the skin and chest strap may not be interrupted also with
greater movements of the thorax such as during deep breathing.
Significant chest chair can interfere with and even prevent con-
tact.
Put on the chest strap a few minutes before starting in order to
warm it up to body temperature and establish optimal contact.
Pairing the signals from the device
The digital transmitters (chest strap, Speedbox, diagnostic scale)
and receiver (HR monitor) have to be paired. If you buy each device
separately, e.g. as a replacement, or if you change the batteries,
then you have to pair the devices before use.
You can find out how to pair the devices by reading the chapter
“Basic settings”, section “Pairing the device signals”.
Connecting the devices
Your HR monitor receives signals from the digital transmitters, chest
strap and Speedbox, as soon as you have activated them and have
changed into the
Training
menu by pressing the
MENU
button.
How you can identify on the display whether signals are being re-
ceived:
If the heart symbol flashes, then the heart rate is being re-
ceived from the chest strap.
If “0” is displayed in the 1
st
line for a longer period, then the HR
monitor cannot receive the signals from the chest strap. The
display “0” can occur in the
Training
,
Time
and
Spd’nDist
menus. In this case, change into the
Training
menu with the
MENU
button. The HR monitor tries once more to make
contact with the devices.
