8.3. Removing the standard 35, 40, ... MHz RF module
1. Locate the lead between the main circuit board and the RF
module, and carefully disconnect it at the module (see
arrow):
! Caution: extra step required for mc-19s and mc-22s
The mc-19s and mc-22s transmitter types feature a second
connecting lead (PPL synthesizer channel select) in addition
to the signal lead:
On both these transmitter types the second connecting lead
should also be disconnected, as it is not required for 2.4 GHz
M-LINK operation. We suggest that you deploy it inside the
transmitter using a cable-tie or Velcro (hook-and-loop) tape.
2. The 35, 40, ... MHz RF module is secured with four screws
at the corners. Undo the four screws, and carefully move the
RF module to one side to reveal the aerial connection:

unit and the LED button
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).

The switch blanking plates are simply clipped into the inside
of the transmitter case.
