2.4 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 the swap button  . .
Entering a new standby frequency can be done by
a) Manual input,
b) Recall of previously stored frequencies from the user memory
(memory locations 1-20), or
c) Recall from the list of the last 10 used frequencies.
2.4.1 Automatic Selection 8.33 / 25 kHz Channel Bandwidth
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 standardized 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 25 kHz-only radios. To use the same frequencies with
8.33 kHz 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.

Operation and Installation

2.4.2 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 FREQ rotary knob.
The swap button  interchanges the newly set standby frequency and
the former active frequency.
When having the channel selection configured for 8.33 kHz steps (see
3.1), the frequency is input in three steps:
SBY
118.910

SBY
118.910

SBY
118.910
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 this
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.

2.4.3 Recall a Frequency from the User Memory
To access the user memory frequency list, press MEM once, and select
one of the 20 memory entries with the VOL/SEL turn knob.
The selected memory entry is shown instead of the standby frequency.
In the lower row of the display, the number of the memory entry selected
is indicated by [MEM xx] (with xx = 1 to 20); if a name has been
provided by the user for this memory entry, it is displayed next to the
memory entry number.

2.4.4 Recall a Frequency from the List of the 10 Last 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 VOL/SEL 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.

2.4.5 Storage of 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 of 1,5 seconds on MEM. The previous
memory entry will be be overwritten.

2.4.6 ATR Frequency Tool
The ATR Frequency Tool from Version 1.3 upwards supports the
ATR833A-II. With the tool the frequency memory of the ATR833A-II can
be managed, i.e. frequencies can be added, edited and deleted. The
frequency list can be stored as a file.
The ATR Frequency Tool can be downloaded from the f.u.n.k.e.
AVIONICS homepage in the service area under Info / Download.

2.5 Basic Settings
To choose between the following settings, use the SET button:
1. VOL Volume (chosen by default)
2. SQL Squelch (noise suppression)
3. VOX Voice Activated Intercom
(speech level required to activate the intercom)
4. INT Volume Intercom
5. STL Volume Sidetone left
6. STR Volume Sidetone right
7. EXT Volume of external audio signals
8. BRT Display brightness
9. CON Display contrast (only for devices with LCD)
…back to Volume
The return to the default display (VOL) is carried out by a short press on
the Dualwatch button DW or happens automatically after 10 seconds of
inactivity.
The chosen setting can be adjusted by the VOL/SEL rotary knob.
2.5.1 VOL –Volume
The radio returns automatically to the volume setting, when a value has
been set with the VOL/SEL turn knob.
Turning the VOL/SEL knob adjusts the volume of received radio signals.
The higher the value, the louder the reception of radio signals.
ACT

SBY
118.275
VOL

Range: 1 –20
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.

2.5.2 SQL –Squelch (noise barrier)
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
118.275
SQL
2
Range: 0 - 9
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).
2.5.3 VOX –Voice Activated Intercom
By shortly pressing the SET key twice, 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=OFF corresponds to “always on”
The default squelch setting is 05. At higher values weak
signals could be suppressed.

Range: Off, 1 - 9
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: 0, and to use an external intercom-switch.
2.5.4 INT –Volume Intercom
By pressing three times the SET button, the volume of the intercom can
be adjusted with the VOL/SEL turn knob.
The intercom functionality is the onboard crew-internal communication
for multi-seater aircraft. A change in the intercom volume level also
changes the volume of the sidetone. The sidetone is an audible feedback
of the own voice to the headset, i.e. you hear yourself speak. This
feature supports a natural speech behavior.
The intercom can be activated in two ways:
Automatically, i.e. whenever someone speaks into a microphone
(i.e. voice activated intercom = VOX, see chapter 0).
Manually, i.e. by use of an external intercom switch.

2.5.5 STL –Volume Sidetone Left
The sidetone is a self-hearing or back-hearing function during
transmission. The audio signal picked up by the microphone is fed
directly to the headset, which is normally perceived as pleasant. In this
menu point the volume of the sidetone for the left seat can be adjusted.
