You no longer need that big transmitter anymore! The programmable OMNI Tx-4.2
handheld transmitter will control your garden railway electric locomotives perfectly
from the palm of your hand. An Omni Rx-4 receiver with be needed to work with the
OMNI Tx-4.2 transmitter in DCC mode, but the Tx4.2 will also operate our standard
r/c Rx2 receivers installed in analogue DC models.
2.4GHz gives perfect glitch free control for up to 800 metres range with no
obstructions.
The Regulator Knob controls speed and direction is controlled be the Reverser
switch. Cruise control is possible by turning off the transmitter while the train is run-
ning. Turn back on to instantly regain control.

Binding Procedure.
Now simpler than ever!
1. Turn on the Receiver (or the model, if it’s
already fitted inside) then….
2. Hold down black buttons 1 and 3, then
turn on the transmitter
3. Successful binding is indicated by LED 2
going ON.
4. Release the two buttons and the job is
done. LED 1 goes solid to indicate that
the Transmitter and receiver are
linked.
13Re-Programming the top Buttons for momentary or
latching operation
This procedure must be started within 20 seconds of turning on the receiver, there-
fore start with the transmitter off and the model switched on. See our website for a
link to video instructions.
First you must put the transmitter into Button Calibration Mode :-
1. With the Transmitter turned Off. Press and hold button 1and 2.
2. Turn the Transmitter On.
3. Both LED’s will start flashing, then go solid, indicating successful entry to
the Button Calibration mode. At this point, release the two buttons. LED 2 now
starts flashing to indicate which button is being calibrated.
Once in Button Calibration Mode, there is no exit except Transmitter power Off.
SELECTING WHICH FUNCTION TO REPROGRAM
LED2 is now flashing in bursts of 1, 2 or 3 quick flashes, indicating which button is
about to be calibrated. One flash indicates button 1 (for functions 1,4,7 or 10) for
adjustment. This can be changed to the next button by pressing button 2, and two
flashes will be seen. Pressed again and three flashes will be seen.
CHANGING BUTTONS FROM MOMENTARY TO LATCHING
The Regulator control knob is used to change the function of a button from latching
to Momentary or Vice Versa. Turn it in the desired direction and the given button
(shown by the number of red light flashes) will be changed.
Fully anti-clockwise = Momentary Fully clockwise = Latched
With LED2 flashing bursts of 1 flash, we are about to program one of 4 func-
tions as shown:
Press button 3 to memorise this setting for FUNCTION 1
Or button 3 + GREEN SHIFT to memorise the setting for FUNCTION 4
Or button 3 + RED SHIFT to memorise the setting for FUNCTION 7
Or button 3 + BOTH SHIFT to memorise the setting for FUNCTION 10
You can now select another button to change, or turn the transmitter off.

Programming the OMNI system to suit your needs.
Your OMNI transmitter and receiver comes to you all pre-set and ready to run DCC
electric trains. Forwards and Backwards on the regulator knob and the three top black
buttons can activate sounds via the DCC interface module. Normally there should be no
need to change these settings, However...
The OMNI R/C system is ideal, in that when you wish to re-program it to suit the special
needs for a particular loco, it is not the transmitter you are re-programming, but the re-
ceiver in the loco. The Transmitter tells the receiver what is expected of it in the future,
and it is the receiver that remembers it. In this way, one OMNI transmitter can control
many different types of locos, each with its own very different requirements.
It is possible to change all or just one of functions from Momentary to latching.
LED 1

Low battery warning
When the batteries in the handset get too low for reliable operation, both LED 1
and 2 start flashing together. Replace them with quality alkaline AAA cells for the
best results,
LED 2
Re-Programming the top Buttons for momentary or
latching operation
(All are momentary by default, except F1 on FRx24 DCC
receivers, which is latching by default)
This procedure must be started within 20 seconds of turning on the receiver, there-
fore start with the transmitter off and the model switched on. See our website for a
link to video instructions.
First you must put the transmitter into Button Calibration Mode :-
1. With the Transmitter turned Off. Press and hold button 1 and 2.
2. Turn the Transmitter On.

CHANGING BUTTONS FROM MOMENTARY TO LATCHING
The Regulator control knob is used to change the function of a button from latching
to Momentary or Vice Versa. Turn it in the desired direction and the given button
will be changed.
Fully anti-clockwise = Momentary Fully clockwise = Latched
Press the required buttons to save the setting for a function.
For example if you want function 12 to be latching, turn the regulator fully clockwise
and press both shift buttons followed by button 3.
You can now select another button to change, or turn the transmitter off.
