this and hold the aerial at an angle, the wiper
contacts in the aerial guide sleeve could be
damaged.
3. Deploy the connecting lead from the RF module
and the aerial unit inside the transmitter:
The connecting lead must pass under the HFM4
M-LINK 2.4 GHz RF module and also to one side
of the MULTIPLEX multi-function socket:
4. Pull the 2.4 GHz aerial unit upwards out of the
aerial guide sleeve to the point where the aerial
joint is visible; you will feel a distinct mechanical
resistance at this point:
Close the transmitter case
1. Carefully offer up the case back panel to the
transmitter, inserting the retaining lugs at the bot-
tom edge, and ensure that both lugs engage prop-
erly (arrows in the picture below):
2. Carefully close the transmitter back panel:
Ensure that no cables are trapped or jammed. It
should be possible to fold the case back into posi-
tion without requiring force.
1. Push the sliders up as far as they will go (away
from the “OPEN” marking):
9.4.3. Ideal Transmitter Aarial Orientation When
Using the Transmitter
When installed, the 2.4 GHz transmitter aerial can be
rotated to either side and swivelled upwards.
Before using the transmitter, the aerial should be an-
gled approximately at right-angles at the swivel joint,
then swivelled either to left or right in the horizontal
plane (see illustrations):
For applications where the model is not operated di-
rectly above or below the transmitter, the optimum ae-
rial orientation is vertically upwards; this applies in
particular to model cars and boats.
! Important:
Never point the aerial directly at the model. For
physical reasons the signal radiated from the aerial is
at its weakest in an imaginary line extending straight out
from the aerial.
9.4.4. Replacing the transmitter battery
a. Switch the transmitter OFF!
b. Locate the snap-catches of the two plastic battery
retainers, pull both of them back in the direction of
the battery, then fold them up ( Fig. 9.4.4.1.).
c. Remove the battery and withdraw the battery con-
nector and lead from the socket on the main circuit
board ( Fig. 9.4.4.2.).

Opening / closing the retainers Connecting the battery
When installing the battery ensure that the connecting
lead is neatly deployed, so that it cannot become trapped
when you close the transmitter back.
