6 Operation
6.1 Introduction
This section contains basic operating procedures for the FSG 2T transceiver. This
instruction is only applicable for a radio which is
 correctly installed and wired by a certified avionics shop or aircraft manufacturer
 checked together with the aircraft system, and
 optimized by the set-up procedure (refer to Section 4, Recommended Set-up
Sequence).
WARNING!
DO NOT OPERATE THIS RADIO IN AN EXPLOSIVE ATMOSPHERE
(PETROLEUM FUELS, SOLVENTS, DUST, ETC.).
6.2 Turning ON - Selecting Frequency - Audio Volume
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.
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. 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 once, the cursor will jump to underscore the
kHz portion.
