3.2 Commissioning
3.2.1 Connecting the CT-DECT Case (8) to the aircraft
The batteries of the CT-DECT Case (8) must be fully charged.
a. Establishing the 9-pin plug-in connection at
the CT-DECT Case (8)
The 9-pole jack of the CT-adapter cable (figure
6) has a distortion protection.
Hold the case down with one hand. Put the jack
onto the 9-pin connector of the CT-DECT Case
(8) and turn it until it slides a little into the con-
nector. With it, the correct plug-in position has
been found.
Now push the jack into the connector until it
engages audibly.
To disconnect the plug-in connection, hold the
case down with one hand and pull the jack out
of the connector.
b Connect the CT-DECT Case (8) with the CT
adapter cable to the intercom connector of the
aircraft.

Î PLEASE NOTE:
During outdoor operations keep the CT-DECT Case (8) always closed!
CAUTION!
The CT-DECT Case (8) may be connected to an aircraft only with the flag “Remove before flight”
attached.
3.2.2 Switching-on of CT-DECT Case (8) and CT-DECT device (PP)
Switch-on, establishing connection, adjusting the volume
Î PLEASE NOTE:
Applies to CT-DECT devices (PP) which are subscribed to a CT-DECT Case (8)
a. First switch on the CT-DECT Case (8) using the green push-button (figure 4/d). The CT-DECT Case
(8) starts now an initialization process during which it may not be switched off. After initialization the
pilot lamp (figure 4/e) lights up. If the pilot lamp (figure 4/f) flashes, the voltage of the batteries in the
CT-DECT Case (8) is low and needs to be recharged.
b. Switch on the CT-DECT devices (PP) you want to communicate with. After switch-on you will hear a
high beep in the headset. After this, synchronization, i.e. the search process, starts between the CT-
DECT Case (8) and the CT-DECT devices (PP), the duration of which may vary. While this process
is under way, a high-low tone sequence will be heard every second in the headsets, indicating, that
the CT-DECT devices (PP) are seeking their CT-DECT Case (8).
After successful synchronization - i.e. a CT-DECT device (PP) found its CT-DECT Case (8) - the high-
low tone sequence falls silent and a high double beep is heard in the headset. CT-DECT Case (8) and
CT-DECT device (PP) establish now automatically the connection between one another. As soon as
the connection is established a final high beep will be heard in the headset. This indicates that the units
are ready for duplex communication within the working range between CT-DECT device (PP) and base
unit.
