Multiplex HFMG1 M-LINK Notice D'utilisation page 13

Fit a silicone insulating sleeve over the aerial connector, then
stow the aerial adapter lead neatly inside the transmitter
case.
Disconnect and remove the 2.4 GHz HFMG1 M-LINK
RF module.
Disconnect the LED button lead from the 2.4 GHz RF
module, and - if present - the channel expansion module
lead.
Install the 35, 40, ... MHz RF module in the transmitter.
Re-connect the transmitter battery (
Fit the 35, 40, ... MHz transmitter aerial** – job done!
** The 35, 40, ... MHz transmitter aerial (telescopic or stub type)
must be removed before the transmitter is operated using the
2.4 GHz M-LINK system.

NSTALLING THE
2.4 GH RF
Z MODULE
! Note: the following section describes the method of
installing the 2.4 GHz HFMG1 M-LINK RF module in a
Graupner mc-24 transmitter.
If you intend to use the RF module in a Graupner mc-18 or
mc-20 transmitter, you can still follow the same basic
procedure.
9.1. Remove the transmitter aerial (35, 40, ... MHz aerial)
1. Switch the transmitter OFF.
2. Unscrew the transmitter aerial.
3. Stow the aerial in the appropriate compartment, or store it in
a safe place.
9.2. Opening the transmitter case
1. Carefully remove the transmitter back cover, and disconnect
the transmitter battery
9.3. Removing the installed 35, 40, ... MHz RF module
1. Lay the transmitter face-down on a soft surface. Ensure that
the sticks, switches etc. are not damaged.
2. Locate the RF module in the transmitter, grasp its case, and
carefully pull it up and out, keeping it straight and "square":
3. Store the removed RF module in a safe place.

9.4. Preparing the transmitter to accept the 2.4 GHz
aerial unit and the LED button
1. Determine your preferred locations (switch wells) for the
2.4 GHz aerial and the LED button:
The 2.4 GHz transmitter aerial and the LED button are each
installed in vacant switch wells to left and / or right of the
transmitter meter. This means that the ball and socket base
for the 35, 40, ... MHz aerial can be left in place on the
transmitter.
At this point you should consider the ideal locations for the
2.4 GHz aerial and the LED button: some positions are likely
to suit your style of flying better than others.
The 2.4 GHz aerial should be installed as far forward as
possible, i.e. towards the transmitter's top panel. The trans-
mitter case must not obstruct the aerial, i.e. there must be
direct "line of sight" contact between aerial and model.
It must be possible to rotate and swivel the 2.4 GHz aerial in
its installed location, so that you can obtain the optimum
signal radiation pattern (
The 2.4 GHz aerial should also be installed in such a position
that it does not prevent you seeing the transmitter meter.
Ensure that your chosen location for the aerial and the LED
button does not restrict access to switches, sliders and rotary
controls, and does not prevent you seeing the meter clearly.
A further point when choosing these locations is the length of
the UNI connecting lead and the aerial lead; these leads
should not be under stress, and must not be kinked (bent
tightly).
2. Remove the switch blanking plates from the two wells you
have selected for the 2.4 GHz aerial and the LED button:
The switch blanking plates are simply clipped into the inside
of the transmitter case.
Working from the inside of the transmitter, push on the
plastic pin in the centre of the plastic column: push the pin
completely out of the column, then squeeze the column
together gently between thumb and index finger: the switch
blanking plate can now be removed from the transmitter.
3. Prepare the hole for the installation of the LED button:
! Note: the hole in the transmitter case has to be modified
in order to accept the LED button. Please work with particu-
lar care here, and keep any metal and plastic swarf well
away from the electronics and the mechanical parts.
The first step is to open up the hole in the transmitter case
for the LED button to a diameter of 8 mm.
When you have finished, use a file to cut a small notch about
0.5 mm long and 3 mm wide; the notch is the right size when
the UNI socket attached to the LED button can just pass
through the modified hole:
