Front Panel
Display
The display shows the primary and standby frequencies and a series of icons to
indicate the operating mode of the radio.
The primary frequency is at the top and the standby frequency is at the bottom
half of the screen. The TX icon shows that the radio is transmitting. An RX icon
shows that the frequency is active and the audio will be heard through the
headphone and speaker outputs. The standby frequency will only be received
during the MONITOR function which is indicated by a +2 icon when active.
The bottom right hand side indicates what frequency step size is selected.
On/Off, Volume and Squelch Knob
The left hand knob controls the power to the VHF radio, adjusts the audio
volume, and controls the squelch. Turning this knob clockwise will switch on
the radio and then increase the volume. Turning anticlockwise will reduce the
volume and eventually will click off.
Pressing this knob toggles the automatic squelch on and off, which can be
used to listen for faint stations and as a simple audio test.
Tuning Knobs
The right hand concentric knobs are used to tune the radio. The large knob
adjusts the MHz portion of the standby frequency, and the smaller knob
adjusts the kHz portion of the standby frequency.

Pressing the end of the small knob changes the channel spacing that the small
knob operates through. If the radio is configured for 8.33 kHz operation, the
steps toggle between 8.33 kHz channels and 25 kHz channels. If the radio is
configured only for 25 kHz operation, the steps toggle between 25 kHz and 50
kHz channels.
Changing the step size does not change the behaviour of the radio, only the
tuning knob step size –it helps to quickly tune a frequency.
Flip-flop Button
The flip-flop button swaps the frequency in the standby position into the
active position, and moves the active frequency to the standby position.
MON Button
The VHF radio includes a dual-frequency listen feature; pressing the MON
button toggles this feature on and off.
When the monitor is active, a +2 icon appears next to the standby frequency,
and the radio will scan between the active and standby frequencies listening
for transmissions. The primary channel has priority –a transmission on the
primary channel will interrupt the secondary channel. As an aid to identifying
which channel is active, the RX icon will light next to the active channel and
the secondary channel will appear slightly quieter than the primary.
This is useful in an aircraft with only a single radio since it allows you, for
example, to copy the ATIS whilst maintaining a listening watch on the ATC
frequency.
Remote Frequency Database
If a compatible GPS is connected, the controller will be loaded with airport
frequencies from the GPS database. These frequencies are accessed by
pressing the MEM button. The airport frequencies and selection order are
determined by the data sent to the controller from the GPS.
EN

The available airports can be scrolled through using the large frequency select
knob. The individual frequencies associated with that airport can be scrolled
through by using the smaller frequency select knob. After you have stepped
through all the loaded airports, or if there is no GPS attached, the built-in
memory of the controller will be displayed.
In each case the selected frequency is loaded into the standby position.
Pressing MEM again leaves the stored frequency in the standby window.
Pressing the Flip-flop button loads the stored frequency directly into the active
channel.
Note: When the controller is displaying the available airport
frequencies it will not accept any new updates from the GPS to avoid
the frequencies changing during selection. To allow the GPS to
update the available frequency database you must come out of
memory mode by pressing the MEM or flip-flop button.
Frequency Memory
If no GPS is connected and the MEM button is pressed, or if the large knob is
rotated beyond the remote database the controller will access the internal
quick reference memory. There are 9 quick reference memory locations and
the bottom edge of the screen will display which memory location is currently
selected (1 –9).
Rotating the small frequency selector knob will step through the memory
locations. The standby frequency window will display the stored frequency.
To store a frequency in one of the memory locations it must first be tuned and
active as the primary frequency. Press MEM to enter the memory mode in the
usual way. Select the channel you want to overwrite with the tuning knobs.

Now press, AND HOLD, the MEM button for 2 seconds. The current active
frequency will be moved to the selected memory location, overwriting the
existing contents.
Intercom Function
The TY91/TY92 radio has a built in intercom which can be installed as
permanently engaged or selected via a switch. The intercom is voice activated
and the audio is routed through to both of the headsets. The intercom squelch
and volume can be adjusted independently from the radio function through
the configuration menu.
Stuck Mic
If the PTT switch is stuck in the ON or transmit position, the radio will
automatically cut out after 35 seconds as a safety measure.
Configuration Mode
Additional setup items can be accessed by holding down the MON button for
5 seconds. The menu options can be selected using the larger inside tuning
knob and the parameter value can be altered using the smaller outside tuning
knob.

Dual Control Operation
If two control heads are installed for a dual control setup then changes made
to one controller will be automatically updated on the second controller.
There is a small time lag between operating one controller and updating the
display on the second controller. This is purely a delay in the display and there
is no delay in the tuning or operation of the TY91/TY92 radio.
The exception is that the radio volume knob works on a “loudest wins” basis.
The radio volume will always correspond to the control head that has the
volume knob set to the highest position. This means that only one of the
controllers needs to be turned up to operate the radio normally, for example
when flying a tandem aircraft solo.
Dual Control Individual Functions
The following functions are local to the individual control head and will not
automatically update or transfer between two controllers:
Frequency Step Size
Changing the frequency step size by pressing the
PUSH/STEP button on one controller does not
affect the other controller.
Brightness
The brightness is separately adjusted on each
controller.
Memory
The frequencies stored in the memory are local to
each controller. The memory data is not
transferred between controllers, although a
frequency selected from the memory will appear
on the screen on the other controller.
General Low Temperature Operation
The TY91/TY92 is certified to operate correctly down to -20°C, but at low
temperatures the controller display may be impaired. On a cold day you may
need to wait for the cockpit to warm up to ensure normal operation.
Warning Messages
If the VHF radio detects a problem, the screen will indicate WARNING and a
brief statement of the problem. Depending on the nature of the problem,
your VHF radio may not be working properly. Note the message on the screen
and pass that information to your avionics maintenance organisation. Press
the flip-flop button to clear the message.

The following warnings may be seen:
Remote Hot
The remote radio is overheating.
Stuck Mic
The PTT switch has been closed for more than 35 seconds.
Low Volts
The aircraft power input is below 10 volts (TY91) or 16 volts
(TY92).
No Radio
Connection between the controller and the remote radio
has been lost.
Radio Fault
The remote radio is reporting an unspecified fault.
Fault Annunciation
If the VHF radio detects a catastrophic internal failure, the screen will indicate
FAULT and a brief statement of the problem. Note the FAULT message at the
bottom of the screen and pass that information to your avionics maintenance
organisation. The fault may be cleared by re-cycling the power to the radio
but if the fault is still present the message will reappear.
Dual Control Warnings and Fault Annunciations
In a dual control head installation, any warning or fault annunciation will be
displayed on both controllers. If one of the controllers suffers a failure, the
second controller may still continue to control the radio. The fault should be
investigated and rectified as soon as possible. It is not advisable to continue to
operate a dual control setup with only one controller operational.

Bedienelemente
Anzeige
Die Anzeige zeigt die Primär- und die Standby-Frequenz sowie eine Reihe von
Symbolen an, die den Betriebsmodus des Funkgeräts angeben.
Die Primärfrequenz steht in der oberen Hälfte des Bildschirms, die Standby-
Frequenz in der unteren Hälfte. Das Symbol TX zeigt an, dass das Funkgerät
sendet. Das Symbol RX zeigt an, dass die entsprechende Frequenz aktiv und
das Audiosignal über die Headset- und Lautsprecherausgänge zu hören ist.
Die Standby-Frequenz wird nur im DUAL WATCH Modus empfangen, der bei
Aktivierung durch das Symbol +2 angezeigt wird.
Unten rechts in der Anzeige wird angegeben, welches Kanalraster gewählt
wurde.
Knopf für Ein/Aus, Lautstärke und Squelch (Rauschsperre)
Der Knopf auf der linken Seite schaltet das VHF-Funkgerät sowie die
Rauschunterdrückung ein und aus und regelt die Lautstärke des Audiosignals.
Durch Drehen des Knopfes nach rechts wird das Funkgerät eingeschaltet und
dann die Lautstärke erhöht. Die Drehung nach links senkt die Lautstärke und
schaltet das Funkgerät schließlich mit einem Klick aus.
Durch Drücken des Knopfes wird die automatische Rauschsperre, die zum
besseren Hören schwacher Funkstellen oder als einfacher Audiotest verwendet
werden kann, ein- bzw. ausgeschaltet.

Frequenzwahlknöpfe
Die konzentrischen Knöpfe auf der rechten Seite werden verwendet, um
Frequenzen einzustellen. Der große Knopf dient zur Einstellung des MHz-
Segments der Standby-Frequenz, der kleinere Knopf zur Einstellung des kHz-
Segments der Standby-Frequenz.
Drückt man oben auf den kleinen Knopf, wird der Kanalabstand für die
Frequenzeinstellung mit dem kleinen Knopf geändert. Ist das Funkgerät für
den Betrieb im 8,33 kHz-Raster konfiguriert, schaltet man so zwischen 8,33
kHz-Kanälen und 25 kHz-Kanälen um. Ist das Funkgerät nur für den Betrieb
im 25 kHz-Raster konfiguriert, schaltet man so zwischen 25 kHz-Kanälen und
50 kHz-Kanälen um.
Die Änderung des Kanalabstands ändert nichts an den Betriebseigenschaften
des Funkgeräts, sondern nur die Schrittweite des Frequenzeinstellknopfes –
dadurch lässt sich eine Frequenz schneller einstellen.
Flip-Flop-Schalter
Der Flip-Flop-Schalter macht die Standby-Frequenz zur aktiven Frequenz und
die aktive Frequenz zur Standby-Frequenz.
MON-Taste
Das VHF-Funkgerät hat eine Funktion, die die gleichzeitige Überwachung von
zwei Frequenzen ermöglicht (Dual Watch); durch Drücken der MON-Taste
wird diese Funktion ein- und wieder ausgeschaltet.
Wenn die Überwachung eingeschaltet ist, erscheint das Symbol +2 neben der
Standby-Frequenz und das Funkgerät scannt die aktive und die Standby-
Frequenz auf Übermittlungen. Der Hauptkanal hat Priorität –eine auf dem
Hauptkanal gesendete Nachricht unterbricht die Kommunikation auf dem
Nebenkanal. Damit besser zu sehen ist, welcher Kanal aktiv ist, leuchtet das
Symbol RX neben dem aktiven Kanal, und der Nebenkanal wird etwas leiser
wiedergegeben als der Hauptkanal.
Das ist bei einem Flugzeug, das nur mit einem einzigen Funkgerät ausgerüstet
ist, nützlich, da man das ATIS abhören und gleichzeitig die Frequenz der
Flugsicherung überwachen kann.
Ferndatenbank für Frequenzen
Wenn ein kompatibles GPS angeschlossen ist, werden Flughafenfrequenzen
aus der GPS-Datenbank in das Bediengerät geladen. Diese Frequenzen
können durch Drücken der MEM-Taste aufgerufen werden. Welche
Flughafenfrequenzen in welcher Reihenfolge ausgewählt werden, wird durch
die Daten bestimmt, die das GPS an das Bediengerät sendet.
