Control Description / Function
1 VOL
Rotary switch and control (inner knob)
To turn ON the radio, rotate the VOL knob clockwise from the OFF
position (dot). When power is activated
the front panel TX/RX LED lights up green momentarily, then
all segments of the display are visible for a short time, to verify
their operation.
The display shows the firmware version and then
the operating mode, which was used before last turning OFF or
Power OFF: The radio is now ready for use.
Rotating the VOL knob clockwise (cw) increases - turning counter-
clockwise (ccw) decreases the audio volume audible via the built-
in loudspeaker or a connected headphone.
To turn OFF the radio rotate the VOL knob fully counter-clockwise
(ccw) to the OFF position (dot ). Blank display.

SQ (SQUELCH)
Rotary control (outer ring)
After turning ON the radio FSG 2T the automatic squelch is active
depending on the SQ knob position.
Standard Operating Mode:
Set the SQ knob to the dot position, the Squelch (mute)
threshold is approximately 1 µV. No Receiver noise should be
audible during Standby. Only received signals above the SQ
threshold are audible.
Rotating the SQ knob fully counter-clockwise (ccw) puts the radio
into the SQ-OFF mode (overrides the automatic squelch). Basic
receiving noise is then audible during Standby. This adjustment
gives maximum receiving range. Slightly increased current
