The different entries of the basic settings can be accessed with
.
1. VOL Volume
2. SQ Squelch
3. VOX Configuration of the threshold value in order to activate Intercom
4. DIM Background Illumination
5. CON Contrast
6. Back to volume setting.
The values are adjusted with the lower rotary knob .
The return to the normal display screen (frequency indication) could be
configured differently (see 2.8.2). In principle this happens by pressing
or . Additionally, the return to the frequency indication can happen
automatically after 5 seconds. Which requires the corresponding setting
in the „Return Mode“ – menu (see 2.8.2). The automatic return to the
frequency indication is a pre-configured factory setting.

2.4 Basic Settings
2.4.1 VOL – Volume
By pressing once, the volume can be configured by using the
lower rotary knob .
Range: 01 - 16
2.4.2 SQ – Squelch
By pressing twice, squelch can be configured by using the
lower rotary knob .
Range: 01 – 10
2.4.3 VOX – Voice Detection (Threshold of IC-Function)
By pressing three times, the voice detection threshold can be
configured by using the lower rotary knob .
VOX defines the volume threshold at which normal noise during flight is
not transferred into the headset. Only an additional voice signal activates
intercom operation.
The VOL-Setting only affects the received signal, not the
Intercom level, which is pre-configured by factory.
The default Squelch setting 03 ... 05. Higher values could
suppress weak signals. Squelch does not impact the
Intercom.

The higher the value, the louder you need to speak in order to activate
the Intercom connection.
Range: 01 – 10
In case of a noisy background or uncompensated microphones it is
possible to deactivate VOX with VOX: 01. If done so, Intercom is enabled
by use of the Intercom-Switch.
2.4.4 DIM – Background Illumination
By pressing four times, the background illumination can be
adjusted by using the lower rotary knob .
This requires a respective wiring (see 3.7).
Range: 01 - 10
2.4.5 CON – Contrast
By pressing five times, the contrast can be adjusted by using
the lower rotary knob .
Range: 01 - 10
Press once more to return to VOL setting.
In order to configure the microphone sensitivity (see 2.8.1.1)
VOX should be set to VOX: 05.

With the input area (MHz or kHz) can be selected:
The selected value is then adjusted with the lower rotary knob .
Now the modified Standby frequency can be activated by pressing
(exchanges active and Standby frequency)
2.5.2 Select frequency from memory position
Turn memory position selector (M1 … M9)
The stored frequency appears and is set as active frequency; hence it is
displayed in the upper row of the screen.
2.5.3 Save a new frequency
In order to save a new frequency this needs to be manually entered and
activated according to the steps described in section 2.5.1.
Select memory position with (M1 … M9).
Memory place and the corresponding
frequency are displayed and active.
The priory manual entered frequency is
kept in memory, but is not yet saved.
Press to finally store the kept
frequency on the selected memory position. The
priory stored frequency is overwritten.

2.6 Transmission
Pushing PTT starts transmission on the selected frequency shown in the
upper line. This operation is indicated by “T”.
„T“ indicates correct operation of the transmitter.
In order to avoid unintended transmission the transmitter stops after two
minutes and the display changes from “T” to “E”.
To re-start transmission, release PTT and push it again.
2.7 Reception
While receiving (squelch is open) “R” is shown.

2.8 Enhanced Settings
In the following section configurations beyond the basic settings are
explained.
Within the INIT Menu two options are provided: reset to factory settings
and the setting of the microphone sensitivity.
The Return Mode Menu enables to configure how the basic settings
menu is left, automatically or manually (see 2.4).
Both menus are only accessible from the switched-off device by pressing
a certain combination of buttons.
2.8.1 INIT – Menu
The Init-Menu is accessed by pressing while switching on with .
Following functions are available:
•MIC - Configuration of the microphone level
•INIT - Reset to factory settings
The selection of the functions is done with the related button beside the
respective menu entry. Any options represented in the upper row are
selected with and (comparably for lower row, see

Therefore the INIT Menu is left with . The device remains
powered-on and returns to normal operation.
2.8.1.1 MIC-Settings
The microphone level simultaneously affects both MIC 1 and MIC 2.
Therefore two equivalent standard microphones must be used to ensure
successful intercom operation.
Within INIT menu press to select MIC
Range: 01 - 32
The microphone level is adjusted with the lower rotary knob .A value
of 01 reflects the lowest sensitivity. Usually a setting between 01…05 is
done for normal avionic headsets.
The microphone level should be configured by use of a headset and
speaking loudly and clearly until VOX is activated / deactivated
satisfactorily.
In order to save the settings and to return to INIT menu press .
2.8.1.2 INIT – Reset to factory settings
Within INIT menu press . This resets the user defined settings as well
as the basic settings (incl. MIC) to the factory settings. The factory
settings are as follows:
MEM1 118.00 VOL 03
MEM2 127.00 SQ 08
MEM3 136.97 VOX 05
MEM4 127.50 MIC 05
MEM5 130.47 DIM 10
MEM6-9 118.00 CON 05
For setting MIC, VOX must be set to 5 previously (refer to
section 2.4.3 page 12).

2.8.2 Return Mode – Menu
The return mode determines if the display automatically returns to
Frequency View after changes by the user (VOL, SQ, VOX, etc.).
In frequency view this affects the lower line (Standby frequency or
memory position) depending on the position of /. The active
frequency is visible at any time also while adjusting the basic settings.
The Return Mode menu is accessed by pressing while switching on
with .
Options: Y/N
The options Y/N (Yes/No) are selected with the lower rotary knob .
Meaning:
Y…Yes Æactivates the automatic return to the frequency view, after
that the menu of the basic settings is left after 5 seconds.
N…No Æonce entered, the menu of the basic settings remains on the
screen (VOL, SQ, VOX, etc.), the basic settings need to be
left manually by pressing or .
In order to save settings and exit the menu press .
