VHF/AM RADIO FSG 2T
6 Operation
June 2014 FAV_D10048 65
6.8 OPTION: AF External
IMPORTANT!
 The Option AF EXTERNAL can easily be enabled! Refer to FSG 2T
Service Manual, Circuit Diagram, page 10 - 28 and Location of
Components, page 10 - 30, just make a solder bridge across W2001.
Then mark the radio accordingly!
 Enabling AF EXTERNAL causes increased current consumption during
Standby!
In Standby, Receive and Intercom Mode, audio signals of additional units (other COM,
VOR, Localizer, Marker, ADF, electric variometer, etc.) are audible simultaneously.
Audio volumes of external audio signals have to be adjusted on the external units
individually but their volume may be reduced by the radio's VOL knob.
The External AF Input is disabled during transmit.
6.9 Backlighting
Depending on aircraft wiring, lighting the frequency display as well as the radio's front
panel (night-design) is either activated by turning ON the panel mounted lighting switch
or dimmer, or by turning ON the FSG 2T radio.
6.10 Turning OFF
Turn OFF the radio by rotating the VOL switch to the full ccw position to prevent
unnecessary discharge of your A/C (or portable case etc.) battery.
If the backlight is wired via panel mounted dimmer or lighting switch remember to turn
this OFF as well, otherwise your battery will go flat.
