3.2 Headsets and Transmitter/Receiver Units

Connect the headset via the connecting cable and plug to its Transmitter/Receiver Unit. Fasten the

Transmitter/Receiver Unit by means of the clip on the rear to a suitable place on your clothing. Put on

the headset.

3.3 Switching on, adjusting the speaker volume

Î NOTES

The Aircraft Interface must always be switched on before the Transmitter/Receiver Units.

On the Transmitter/Receiver Units the push-buttons for connection setup and connection

release, placed in the middle of the push-button bank, must not be pressed until the

Transmitter/Receiver Units are synchronized with the Aircraft Interface.

Always leave the Aircraft Interface and the Transmitter/Receiver Units switched on as long as

you work with the communication system so that immediate availability of the system is

provided.

a. First switch on the Aircraft Interface by means of the green push-button ON (Fig. 2/e). The control

lamp (Fig. 2/f) illuminates. If the Battery Pack voltage is too low the control lamp flashes and the

Battery Pack must be charged.

b. Switch on the Transmitter/Receiver Unit by means of the On/Off switch and volume control (rotary

knob).

After Switching on the connection synchronization between Transmitter/Receiver Unit and Aircraft

Interface is effected automatically.

Synchronization: A click is audible in the headset connected to the Transmitter/Receiver Unit

approximately 10 seconds after switching on. The synchronization procedure then begins, i.e. the

previously switched on Aircraft Interface seeks its Transmitter/Receiver Unit. This synchronization

procedure can last approx. 30 seconds. Upon completion of synchronization – i.e. the Aircraft

Interface has found its Transmitter/Receiver Unit – a high double-beep P-tone sounds in the

headset, indicating that the Transmitter/Receiver Unit and the Aircraft Interface are ready for

operation.

c. At the Transmitter/Receiver Unit set the On/Off switch and volume control (rotary knob) to mid-

position. Later, on voice reception, adjust the desired speaker volume for your headset. Do not set

the volume any higher than necessary.

d. Connection setup and release by the Transmitter/Receiver Units see sections 3.4...3.4.2.

3.4 Connection setup and release by the Transmitter/Receiver Unit(s)

3.4.1 Prerequisites

y Aircraft Interface and Transmitter/Receiver Unit(s) subscribed (sections 7...7.4)

y Aircraft Interface and Transmitter/Receiver Unit(s) switched on and synchronized (section 3.3)

3.4.2 Connection setup and release

Automatic connection setup after switching on

After the Aircraft Interface and the Transmitter/Receiver Unit(s) are switched on the connection

synchronization between the the Aircraft Interface and the Transmitter/Receiver Unit(s) is(are) effected

automatically. Subsequently communication is possible.

Connection release

Briefly press one of the push-buttons for connection setup and release in the middle of the push-button

bank at the Transmitter/Receiver Unit. The Transmitter/Receiver Unit is disconnected from the Aircraft

Interface. This procedure is acknowleded by a high beep P-tone in the headset connected to the

Transmitter/Receiver Unit.
