Operating instructions

Transmit the transmitter
code to the receiver (see
operating instructions of the
receiver / radio control).

This function allows to trans­fer the codes of one trans­mitter to other hand transmit­ters.

1. Connect the source
transmitter to the target
transmitter using the pro­gramming connector.

2. Press and hold the se­lected channel button of
the source transmitter.
The LED in the source
transmitter lights up.

3. Press and hold the re­spective channel button of
the target transmitter. The
LED in the target trans­mitter initially starts flash­ing and then lights up af­ter approx. 2 sec.

4. Release the channel but­tons and to remove the
programming connector.
The programming is com­pleted.

Repeat steps 1 to 4 for pro­gramming each individual
channel.

This function allows the re­ceiver to be re-coded in case
a transmitter is lost.

1. Put the programming
connector into the trans­mitter to be re-coded.

2. Short-circuit one of the
two outer wires of the
programming connector
with the centre wire.

3. Press the respective
channel button for approx.
5 seconds. The channel is
coded anew (random
programming).

4. Release the channel but­ton of the transmitter and
remove the programming
connector. The re-coding
is completed.

Repeat steps 1 to 4 for re­coding each individual chan­nel.
Note: The new coding must
be transferred to the receiver
(consult the operating in­structions of the receiver /
radio control).

Press and hold the button
until the LED lights up.

Insert a small coin into the
notch on the top of the
transmitter. Turn the coin
diagonally and carefully pull
the housing parts apart.
Replace the battery. Use
only batteries of type
CR2032. Observe the cor-

rect polarity!
Caution! Keep batteries out

of reach of children!

The LED is only faint when lit
up: change the battery.
The LED does not light up at
all: Check the polarity of the
battery.
The receiver still does not
respond: move closer to the
radio control or re-transmit
the transmitter codes to the
receiver.
