Setting The Frequency / Channel; The Rf Status Indicator (Blue Led) - Multiplex Cockpit SX Manual De Instrucciones

Key to the signal strength display:
no signal weak
measurable
You can now use the 3-D digi-adjustor to select a dif-
ferent frequency / channel; the screen will then display
the signal strength on that frequency.
b. Frequency / channel is free
The channel No. does not flash. A brief press
3-D digi-adjustor confirms the selected setting for the
frequency / channel.
Your press is confirmed by a beep, and the blue LED
starts to flash. The transmitter is now ready to use.
The procedure now continues as described in Section
10.2.3., unless the warning THR >0 appears on
the screen (throttle control not in the idle / motor OFF
position.

10.3. Setting the frequency / channel

The procedure for setting the frequency / channel is
simple, fast and safe thanks to the transmitter's integral
Synthesizer RF.
Simple, because the frequency and channel are
displayed on the screen.
Fast, because the 3-D digi-adjustor is used to select
the frequency / channel.
Safe, because the transmitter must be switched off and
then on again before a change of frequency /
channel takes effect. You also have to confirm
your chosen frequency with a brief press on the
3-D digi-adjustor every time you switch on.
Note: no RF signal transmitted during frequency
setting
No RF signal is transmitted while you are selecting the
channel / frequency.
This is the procedure:
1. Hold the 3-D digi-adjustor pressed in
Switch the transmitter on
Release the 3-D digi-adjustor
The screen now displays the current frequency,
with the associated channel number flashing.
The blue LED glows constantly.
2. Selecting the channel
You can now use the 3-D digi-adjustor to
search for the channel you wish to use. The
screen also displays the associated frequency.

3. Confirming the channel
A brief press on the 3-D digi-adjustor con-
firms your choice, and this display appears:
4. Activating the frequency / channel
Switch the transmitter off, then on again.
(do not press the 3-D digi-adjustor).
The procedure now continues as described in the
previous section 10.2.
Notes:
Check with other pilots !
(frequency control, channel clashes)
Check with the other pilots at the site which fre-
quencies / channels they are using. Do this before
you change to a new frequency / channel.
Select approved frequencies / channels only !
The permissible frequencies / channels vary from
country to country. Select only those frequencies /
channels which are approved for use where you
are operating your equipment.
Please refer to the sheet entitled "R&TTE" in the
transmitter documentation.

10.4. The RF status indicator (blue LED)

The blue LED (light-emitting diode)
indicates the status of the RF
module. It only lights up when the
transmitter is switched on.
LED flashing
The LED flashes briefly at intervals of around 1 second
to indicate that the transmitter is ready for use, and is
transmitting an RF signal.
LED glowing constantly
If no RF signal is being transmitted, the cause may be
any of the following:
• Frequency / channel not yet confirmed after the
transmitter has been switched on
• Plug present in the multi-function socket;
this switches the RF section off
(Diagnosis lead, Pupil lead on Trainer cable, PC
simulator interface)
• Transmitter deliberately running without an RF signal
(long press on the 3-D digi-adjustor after switching
on)
• Technical fault in the RF section
