2. Removing the copper plate ("shielding plate") which is glued
in place:
! Note: this step only applies to transmitters of the PROFImc
3010 and PROFImc 3030 types!
Check whether there is a copper plate (arrow!) glued into the
RF module well of your transmitter
(if not: continue with step 3.):
Locate the cable connected to the circuit board and the
copper plate, and snip if off as close to the circuit board
as possible.
Carefully press the glued copper plate out of the RF module
well, and remove it.
3. Slip the aerial wire (attached to the RF module) through the
exposed opening in the RF module well, and thread it
through the opening in the top of the transmitter:
4. Undo the nut from the threaded aerial base, and fit the aerial
cable with shakeproof washer through the central opening in
the 2.4 GHz aerial support plate; note the slightly flattened
area on one side which prevents it rotating. Fit the nut again
and tighten it (see also the photo below).
5. Locate the 3-core UNI connecting lead attached to the 2.4
GHz aerial support plate, and fit it through the hole in the top
of the transmitter and the opening in the RF module well:
! Note: if you also intend to fit the 13 / 16 channel
expansion unit # 7 5810 in the PROFImc, this is the best
time, i.e. before the aerial support plate is attached to
the transmitter.

This module provides four auxiliary channels in 2.4 GHz
mode, e.g.:
- PPM9 => auxiliary channels 10 ... 13
- PPM12 => auxiliary channels 13 ... 16

Black wire: negative
Red wire: positive
Yellow wire: signal
Don't connect the lead with reversed polarity:
! Note: if you are installing the 13 / 16 channel expan-
sion unit # 7 5810 in the PROFImc, insert the connector
in the 2.4 GHz RF module now!
Take care to maintain correct polarity! See the notes on
the underside of the RF module!
RF module well, using steady pressure. Deploy the cables in
this area between the RF module well and the aerial adapter
plate. Note the correct orientation of the 2.4 GHz RF module:
