2.4 Basic Settings
To choose between the following settings, use the SET button:
0. VOL ...... Volume (chosen by default)
1. SQL ...... Squelch
2. DIM ....... Backlight ON/OFF
3. VOX ...... Speech level required to activate the intercom
4. DWM ..... Dual watch mute
5. INT ........ Intercom volume
6. EXT ....... Volume of external audio signals
…. back to Volume
The return to the default display (VOL) is carried out by a long press of
SET or happens automatically after 12 seconds of inactivity)
The chosen setting can be adjusted by the
rotary knob.

2.4.1 VOL - Volume
Can be reached by a long press of the SET button, but is also
automatically chosen by the radio after 12 seconds of user inactivity.
Adjusts the volume of received radio signals by turning the
knob. The higher the value, the louder the reception of radio signals.
ACT

SBY
118.910
VOL 03
2.4.2 SQL - Squelch
By shortly pressing the SET key once, with the help of the
rotary knob the squelch level can be adjusted. (Note: This is not related
in any way to the intercom functionality.)
This is a threshold that has to be exceeded by radio signal levels from
other transmitters, in order to activate the reception circuitry. The higher
the number, the stronger the radio signals have to be in order to be
received.
ACT
123.450
SBY
118.910
SQL 07
The setting for the squelch depends on different factors. For motor
aircrafts an initial higher setting is typically appropriate, gliders may use a
lower value. A lower number means higher input sensitivity. This allows
reception of weaker signals (radio stations at higher distance), but can
also result in pickup of own-aircraft radio interference sources (engine,
strobe lights).
The VOL setting controls the volume of received radio
signals only, not the volume of the intercom or the external
audio input – these are set separately with INT and EXT .
Range: 01 – 16

By shortly pressing the SET key twice, with help from the
rotary knob the backlight of the display can be switched on and off.

2.4.4 VOX – Voice Detection (Speech Threshold for Voice
Activated Intercom)
By shortly pressing the SET key three times, with the help of the
rotary knob, the threshold volume VOX for intercom voice
detection can be adjusted. (Note: This is not related in any way to radio
reception or squelch.)
VOX defines the crew’s speech volume that is required to activate the
intercom functionality. The higher the value, the louder you need to
speak in order to activate the intercom.
Exception: VOX 01 corresponds to “always on”
The internal filter circuitry has the ability to distinguish between engine
noise and speech.
ACT
123.450
SBY
118.910
VOX 05
In case of very noisy backgrounds or use of uncompensated
microphones, the automatic VOX functionality may not work satisfyingly.
In these cases, it is possible to deactivate the VOX automatism with VOX
01, and to use an external intercom-switch.
The default Squelch setting is 05. At higher values, weak
signals could be suppressed.
Range: 01 – 10
Range: ON – OFF

2.4.5 DWM – Dual Watch Volume Reduction
By shortly pressing the SET key four times, with help from the
rotary knob the lowering of the volume level (“mute”) for
receptions on the standby frequency (when having dual watch active)
can be controlled. This allows acoustic distinction between both
frequencies.
For further information about the dual watch mode see 2.6.

SBY
118.910
DWM -2
2.4.6 INT - Intercom-Volume
By shortly pressing the SET key five times, with help from the
rotary knob the intercom volume level can be controlled.
The intercom functionality is the on-board crew-internal communication
for multiple-seated powered aircraft.
The intercom can be activated
• automatically whenever someone speaks into a microphone (i.e. voice
activated intercom = VOX, see 2.4.4).
• manually by use of an external intercom switch.
The higher the value, the higher the intercom volume.
ACT
123.450
SBY
118.910
INT 03
If the intercom is deactivated by cabling, the intercom
volume cannot be adjusted. The radio indicates this by
displaying INT --
Range: -8 – 00
-8 is highest muting (dual watch reception at much lower volume)
00 is no muting (dual watch reception at same volume)
Range: 01 – 10
