4.6 Turning ON - Selecting Frequency - Audio Volume
CAUTION!
The
FSG 2T PS
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.
IMPORTANT!
Frequent transmissions as well as large receiving volume
reduce the operating time when radio is only powered by the
built-in battery!
Turn the radio
FSG 2T
ON by rotating the
VOL
knob
1
clockwise.
For a short time the
TX/RX
LED
4
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.
No warm-up period is required. However, at temperatures of approx.
-20°C / -4°F, the LC display needs approximately one second until it
is fully visible when the frequency or operating mode is changed.
To change the operating mode and therefore the display: Press
the
F/CH
button

.
Example:
STANDARD:
DIRECT TUNE MODE
After switching ON the radio, either the MHz portion or the kHz
portion of the displayed frequency is underscored. The underscore
indicates accessibility to this portion.
Assume the MHz is underscored: Select the appropriate MHz
portion by rotating the
F/CH
knob 6 . A clockwise rotation will
increment the previous frequency in 1 MHz steps (130, 131, 132
etc.) while a counter-clockwise rotation will decrement the
previous frequency in 1 MHz steps (128, 127, 126 etc.) with
rollover at each band edge (118.XX 136.XX or 136.XX
118.XX).
Press the
F/CH
knob
6
once, the cursor will jump to underscore
the kHz portion.
The underscored kHz portion of the frequency indicates accessibility
to kHz selection.
Select the appropriate kHz portion by rotating the
F/CH
knob
6
.
A clockwise rotation will increment the previous frequency in
25 kHz steps (37, 40, 42 etc.) while a counter-clockwise rotation
will decrement the previous frequency in 25 kHz steps (32, 30, 27
