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.

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

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.

SBY

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.

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.

If the intercom is deactivated by cabling, the intercom
volume cannot be adjusted. The radio indicates this by

2.4.7 EXT - Volume of the External Audio Input
By shortly pressing the SET key six times, with help from the
rotary knob, the volume from the connected external audio signals
(Warning tones, music, etc…) can be set.
The higher the value, the higher the volume of the external audio signal.
A value of 00 deactivates the external audio input.
ACT

SBY

When no other device is connected to the external audio
input, the input should be muted by selecting 00, in order to
prevent noise by pickup of on-board interferences.

comparison to radio
receptions can be configured, see 3.5.

2.5 Frequency Setting
Frequency setting is always done by the two steps of
1. entering a new standby frequency to the desired value, and then
2. interchanging the new standby frequency and the previous active
frequency by using ▲▼ .
Entering a new standby frequency can be done by
a) manual input ,
b) recall of previously stored frequencies from the user memory, or
c) recall from the list of the last 10 used frequencies.
2.5.1 Automatic 8.33 / 25 kHz Channel Width Selection
Whether a frequency is used with channel width 8.33 kHz or 25 kHz, is
automatically determined by the value of the frequency entered, and
requires no additional user activity.
The numbering scheme that is used for distinction of the two channel
widths is internationally standardised by the ICAO, and consistently used
in official documents (like e.g. VFR navigation charts) as well as in the
voice phraseology used by ATC radio communication.
Channels used with 25 kHz width are entered in multiples of 25kHz:
123.500, 123.525, 123.550, 123.575, 123.600 etc. These are compatible
with the old 25kHz-only radios. To use the same frequencies with
8.33kHz width, the frequency values entered are increased by 5kHz:
123.505, 123.530, 123.555, 123.580, 123.605 etc.
For more detailed information please refer to chapter 5.1 – but as said
above, for correct channel width selection this knowledge is not required.
2.5.2 Manual Frequency Input
The standby frequency is input by
•selecting with the ►button which part of the frequency to
change, and
•changing the selected part with the rotary knob.
The selected part of the frequency is marked with the underline.
▲▼ interchanges the newly set standby frequency and the former active
frequency.

When having the channel selection configured for allowing 25 kHz
channels only (see 3.1), the frequency is input in two steps:

↔

2.5.3 Recall a Frequency from the User Memory
To access the user memory frequency list, press MEM once, and select
one of the 100 memory entries with the turn knob.
The selected memory entry substitutes the former standby frequency.
In the lower row of the display, the number of the memory entry selected
is indicated by [MEM xx] (with xx = 00 … 99); if a name has been
provided by the user for this memory entry, it is displayed next to the
memory entry number.

▲▼ interchanges the newly set standby frequency and the former active
frequency, and leaves the memory list menu.
If no input is done for 12 Seconds, the device returns to the standard
view, too.
In order to speed up the entering of new frequencies, it is
possible to configure the radio to allow entering of those
frequencies only that are used with 25 kHz channel width.
Please refer to chapter 3.1 for information on th
is
configuration.
However, when choosing this option, please keep in mind to
re-enable 8.33 kHz channel selection before
flying into areas
where 8.33 kHz channels are used.

The radio automatically keeps track of the last 10 used active
frequencies. To access this list, press MEM twice, and select one of the
10 list entries with the turn knob. The selected memory entry
substitutes the former standby frequency.
The number of the selected list entry is given in the display’s lower row.

2.5.5 Store a Frequency into the User Memory
The active frequency can be stored into any entry of the user memory.
This is achieved by a long press on MEM when having the user
memory entry to be overwritten selected.
The following example stores the frequency 124.350 MHz of KONSTANZ
into the user memory entry 07:
List entry „00“ contains the last standby frequency from the
MEM menu.
