7.4.2. Adjusting the transmitter aerial,
fitting a new aerial
The transmitter aerial is a permanent fitting in the case.
For transport it can be collapsed completely and re-
cessed into the case. For adjustments and programming
the aerial can be left in this position without damaging
the RF section.
! When operating a model always extend the ae-
rial to its full length. Only in this configuration
can you be sure of safe operation with maximum
radiated power and range.
The aerial can also be moved to a second position (an-
gled up and to the left), and locked in that position:
1. Pull out the aerial until you feel a distinct resistance
(Fig. 1).
2. Pull the aerial another 3 to 5 mm to overcome the
resistance, pulling fairly hard, and swivel the aerial
up and to the left (Fig. 2). You will again feel resis-
tance at this point, but this time do not push past it.
3. Tilt the aerial as far as it will go, and it will latch in
the correct position..
To swivel it back, the aerial must first be unlocked again
as described under point 2.
! Check regularly that the aerial is still making
good contact. Contact problems with telescopic
aerials cause adverse effects on radiated power,
and thereby reduce effective range. In such situa-
tions reliable operation can no longer be guaran-
teed. Intermittent contact or bent aerials should
be replaced at the earliest opportunity, as should
an aerial that has become loose and sloppy
through hard use.
If the aerial should be damaged, it can be replaced eas-
ily as follows: Remove the case back, and simply push it
back and out of the aerial guide sleeve (replacement
ROYALevo aerial: # 89 3002).

7.4.3. Installing and removing the RF module
The two RF modules (HFM-4 and HFM-S) for the ROYA-
Levo are not fitted in protective cases. To avoid dama-
ging them:
• Don’t touch the circuit board and its components.
• Don’t exert any force on the circuit board.
• Protect RF modules from mechanical strain.
!!
Don’t touch components on the circuit board.
Don’t change the settings of adjustable compo-
nents.
If settings have been changed mistakenly or com-
ponents are damaged, have the module checked
an realigned by the MULTIPLEX service.
Removing the RF module:
1. Switch off the transmitter!
2. Open the transmitter (è 7.4.1.)
3. Lay the front face of the transmitter on a soft sur-
face, taking care to avoid damage to the sticks and
switches!
4. Grasp the RF module by all four corners using both
thumbs and index fingers, and carefully pull it up
and out (see picture below).
Replacing the RF module:
Grasp the RF module as before. Ensure that the module
is fitted onto the contact pins correctly, i.e. that it is not
offset in any direction.
! When changing the RF module avoid touching
the electrical components at all costs. If the mod-
