Opening / closing the transmitter case

! Switch the transmitter OFF before opening the
case (short-circuit hazard)!
Opening the transmitter case:
OPEN
Fig. 9.4.1.1.
a. Hold the transmitter in both hands, and push the
rear-mounted sliding latches down with both
thumbs (towards "OPEN") ( Fig. 9.4.1.1.).
b. Carefully remove the rear case panel
( Fig. 9.4.1.2.).
Closing the transmitter case:
Fig. 9.4.1.3.
c. Carefully stand the case at an angle on its rear edge,
and engage the two retaining lugs on the back panel
in their recesses
(arrows in  Fig. 9.4.1.3.).
d. Carefully close the back panel ( Fig. 9.4.1.4.).
! Ensure that no wires are trapped, and that the
transmitter aerial has not slipped out of its guide
tube. It should be possible to fit the case back
easily, without using force.
e. Push the sliding latches up as far as they will go
(opposite direction to "OPEN").

Removing / installing the RF module

The following section describes the method of
installing the HFM4 M-LINK 2.4 GHz RF module in a
transmitter of the ROYALevo, ROYAL SX or ROYAL
SX M-LINK type.
Open the transmitter case
! Switch the transmitter OFF before opening the
case (short-circuit hazard)!
1. Hold the transmitter in both hands, locate the slid-
ing latches, and push both of them down using
your thumbs (in the direction marked "OPEN"):

CLOSE
Fig. 9.4.1.4.
2. Carefully remove the back cover of the transmitter
case.
Plug in the HFM4 M-LINK 2.4 GHz RF module
1. Remove the HFM4 M-LINK 2.4 GHz RF module from
the protective anti-static bag, and hold it as described
above.
2. Carefully insert the RF module using steady pres-
sure.
Ensure that the module is fitted on the correct pins,
and is inserted "squarely", i.e. not canted over:
Fit the 2.4 GHz aerial unit
1. Screw the 2.4 GHz aerial to the aerial base:
 Hold the aerial by the knurled section.
 Check that the resultant screwed joint is firm, to
ensure that the aerial cannot possibly come
loose in use, e.g. when swivelled in the installed
state:
! Note: avoid using excessive force, and keep
the parts correctly aligned when screwing them
together.
2. Set the prepared 2.4 GHz aerial unit straight (not at
an angle), then carefully slide it into the aerial
guide sleeve from the bottom end.
! Caution: the swivel base on the top face of
the transmitter must lie parallel with the aerial
guide sleeve during this stage. If you ignore
