4 Recommended Set-up Sequence
IMPORTANT!
To get easy access to the potentiometers and DIL Switches on the
rear the radio should not be fixed in the instrument panel at that time!
Loosen the upper cross-recessed screws of the rear panel and move
up cover to get access to the potentiometers and DIL Switches.
Make all settings in the usual environmental noise (e.g. engine in
cruising rpm)!
During adjustment of Microphone Level and TX Sidetone the
transmitter is keyed. Carry out this setting quickly!
When using two headsets, make sure the second headset is also
connected. If the second headset is not worn, the headset boom mike shall
be moved as far as possible away from earphone transducer and / or well
padded in order to avoid acoustic feedback. It would be even better if a
second person is wearing the second headset during microphone and
phone level adjustment.
Parallel operated microphones and / or earphones must have the same
specifications. The following adjustment has to be repeated when changing
microphones (brand, type or number)
It should be noted that use of two microphones connected in parallel
significantly reduces the microphone(s) output level (particularly important
when in an installation both microphones can be plugged).
4.1 General
CAUTION!
The FSG 2T should be turned ON after engine start-up. This is a
simple precaution which helps to protect the solid state circuitry
and extends the operating life of your avionics equipment.
Turn the radio FSG 2T ON by rotating the VOL knob clockwise. For a short time the
TX/RX LED lights up green and all segments of the display are visible to verify their
operation. After indicating the Firmware version, the last used operating mode and
frequency are displayed.
Select an appropriate (test) frequency, e.g. 122.90 MHz.
Check the SQ control. From the full counter-clockwise position (RX noise, signaling
TX/RX LED lights GREEN) rotate the SQ knob until the noise stops and – without
received signal – the TX/RX LED turns clear. When receiving air traffic communication
the TX/RX LED stays GREEN. Set the RX volume of the aircraft loudspeaker or
headphone to a convenient level by rotating the VOL knob.
