connection terminal X31 and its posi-
tion.
7.2 Connecting to the
communication unit
1. Unclip the unit mounting bracket from
the communication unit.
2. Connect the enclosed cable (1) to the
communication unit and, in doing so,

7.3 Requirements for the
installation site 6,
1. Avoid interference between the com-
munication unit and its environment
(magnetic fields, electrical units, metal
structures, etc.).
2. Determine a location in order to start
the search.
3. To determine the best possible signal
strength for the mobile network, move
the communication unit in order to de-
termine the installation site.
4. Each time you move the communica-
tion unit, wait for 10 seconds in order
to test the signal strength of the mobile
network.
Condition (signal strength of the of the
mobile network/communication with the
server): Meaning of the network LEDs
(→ Page 18)
◁
The illuminated LEDs display the
signal strength of the mobile net-
work.
◁
The LEDs automatically go out after
30 minutes. The signal strength of
the of the mobile network is then no
longer updated.
5. Mark the drill holes.
