4.6 Transmitter pairing
The speed and cadence signals (Option: Item no.
7702) will be transmitted digitally and encoded to
your computer. This technology is less prone to
problems than analogue transmission. This way,
when riding in a group there are no data overlaps
(cross talk). So that the computer acquires the
digital encodings from the transmitter, a pairing
must be made:
step 1
Place the computer into the handlebar
holder. The display for the speed and the cadence
now flashes. The flashing shows that the computer
is looking for its transmitter.
step 2
Spin the front wheel or simply set off and
the computer acquires the digital encodings.
When the computer has found the transmitters
and has acquired the encodings (pairing), the
speed and cadence are shown on the display.
ATTENTION: The time window for pairing is
5 minutes. If you do not start cycling during these
5 minutes, no pairing takes place. Speed and
cadence are not displayed. The pairing
then has to be repeated:

You must set the wheel size (wheel roll circum-
ference) of your bike so that your VDO computer
can measure correctly. There are 2 ways of
doing this:
The common types of tyres are listed in the tyre
table. If your tyre type is not listed, we recommend
entering the wheel size manually.
The values given in the table are approximate
values. These values differ according to brand, tyre
height and tyre profile. This can consequently also
lead to discrepancies in the distance measured
and the speed shown.

cally returns to the start menu SETTINGS/SELECT.
