Before you modify the transmitter you must decide whether you
wish to be able to continue to use the unit on the 35, 40, ... MHz
band in the future, as well as on the 2.4 GHz band.
6.1. The transmitter is to be converted permanently to
MULTIPLEX M-LINK 2.4 GHz technology
In this case the 2.4 GHz aerial unit with push-button and LED is
mounted permanently at the top of the PROFImc in place of the
35, 40, ... MHz aerial plate (with ball socket).
6.2. The transmitter is to be capable of operating both on
2.4 GHz and 35, 40, ... MHz in future
In this case the 2.4 GHz aerial unit with push-button and LED is
mounted to one side of centre in a switch well, using the optional
2.4 GHz aerial adapter lead for PROFImc, # 7 5116. This pre-
serves the ball socket for the 35, 40, ... MHz aerial**. This option
enables the user to swap the HFM3 M-LINK 2.4 GHz RF mo-
dule for the previously used FM RF module. This can be done at
the flying site, as the job takes just a couple of minutes:
Release the 2.4 GHz aerial adapter cable connection.
Pull the silicone sleeve over the aerial connector to insulate
it, and deploy the aerial adapter lead neatly inside the
transmitter case.
Disconnect the HFM3 M-LINK 2.4 GHz RF module.
Disconnect the lead for the LED and push-button from the
2.4 GHz RF module, and also the lead for the 13 / 16
channel expansion unit, if fitted.
Insert the 35, 40, ... MHz RF module.
Screw the 35, 40, ... MHz aerial into the socket** - job done!
** The telescopic 35, 40, ... MHz aerial must be removed from
the transmitter when the unit is operating on 2.4 GHz.

NSTALLING THE
HFM3 M-LINK 2.4 GH
The following section describes the method of installing the HFM3
M-LINK 2.4 GHz RF module in a PROFImc 3010, PROFImc
3030 or PROFImc 4000 transmitter.
! Note: we assume that you wish to convert the transmitter per-
manently to MULTIPLEX M-LINK 2.4 GHz technology (
If you wish to continue to operate the transmitter on 35, 40, ...
MHz ( 6.2.), you will find the necessary steps described in the
installation instructions for the PROFImc 2.4 GHz aerial adapter
lead, # 7 5116.
7.1.: Remove the transmitter aerial (35, 40, ... MHz telesco-
pic aerial)
1. Unscrew the transmitter aerial.
2. Place the aerial in the storage well on the back of the trans-
mitter, or store it in a safe place.
7.2.: Open the transmitter case
! Switch the transmitter OFF before opening the case
(short-circuit hazard)!
1. Hold the transmitter in both hands and press the push-
buttons on the top of the transmitter using both thumbs:

2. Carefully remove the back cover of the transmitter case.
7.3.: Remove the installed 35, 40, ... MHz RF module
1. Lay the transmitter face-down on a soft surface. Take care to
avoid damaging the sticks and switches!
2. Locate the RF module inside the transmitter, grasp the case
by the thumb and index finger, and carefully withdraw it:
3. After removing the RF module, store it in a safe place.
7.4.: Remove the 35, 40, ... MHz aerial support plate
1. Remove all four retaining screws in the aerial support plate
on the top of the transmitter (the screws will be needed again
later).
2. Move the aerial support plate forward by a few centimetres,
then lift it off.
3. Snip off the aerial cable (wire connecting the circuit board to
the aerial ball socket) as close as possible to the circuit board.
6.1.).
7.5.: Installing the HFM3 M-LINK 2.4 GHz RF module and the
2.4 GHz aerial support plate
1. Carefully expose the rectangular opening in the RF module
well by cutting through the sticker as shown below:
