VHF/AM RADIO FSG 2T
6 Operation
64 FAV_D10048 June 2014
6.7 Intercom (Option AF EXTERNAL enabled)
IMPORTANT!
 When the Option AF EXTERNAL is activated voice controlled Intercom
is not possible!
 To achieve best cabin noise suppression, especially during speech pauses,
optimized microphone sensitivity adjustment must be performed once
during Installation Procedure.
 Intercom headset audio volume may be adjusted through installation and
should also include, if applicable, the individual earphone volume
adjustments on the headset phone capsule.
1. Switch ON Intercom. This disables the speaker.
2. In Receive Mode, through acoustic accessories (earphones with microphones), the
FSG 2T allows continuous intercommunications between pilot(s) and / or other crew
members. Always speak loud and clear, while the microphone opening is located
close to the lips.
3. The Intercom audio volume may be adjusted by setting the front panel VOL knob.
4. Receive, Intercommunication and External Audio are audible while Intercom is ON.
When Receiving, Intercommunication is reduced by 6 dB / half level in volume. This
allows safer listening to the RX signal.
5. By pressing the PTT key the radio switches to transmit – without switching OFF the
Intercom – but disables the VOX threshold temporarily. The transmitter modulation
Sidetone is audible in all connected headphones. The TX/RX LED on the front panel
flickers according to the speech volume. This also allows optical monitoring of
transmission quality (time constant controlled).
6. Releasing the PTT key turns the radio into Intercom Mode again.
