Note:
check the module orientation: the aerial must face
forward and up, i.e. towards the top face of the transmitter!
The
HFMG3 M-LINK 2.4 GHz RF module
is correctly inser-
ted when the retaining clips on both sides of the RF module
engage distinctly (“click”) in the RF module recess:

DEAL POSITION OF THE TRANSMITTER
AERIAL WHEN USING THE SYSTEM
The 2.4 GHz transmitter aerial swivels, and can be set to any
angle.
Before using the transmitter, the aerial should be angled
approximately at right-angles at the swivel joint, then swivelled
either to left or right in the horizontal plane:
For applications where the model is not operated directly above
or below the transmitter, the optimum aerial orientation is verti-
cally upwards; this applies in particular to model cars and boats:
!
Important:
Never point the aerial directly at the model. For physical reasons
the signal radiated from the aerial is at its weakest in an imagi-
nary line extending straight out from the aerial.
!
Note:
Always remove the 35, 40, … MHz transmitter aerial (telescopic
or short aerial) before operating the 2.4 GHz M-LINK system.

EPLACING THE
2.4 GH
Z TRANSMITTER
AERIAL
The 2.4 GHz transmitter aerial is permanently attached to the
HFMG3 M-LINK 2.4 GHz RF module
.
!
Note: on no account attempt to replace the 2.4 GHz trans-
mitter aerial yourself!
Special tools and technical expertise are required to replace the
aerial in a competent manner. If the transmitter aerial should be
damaged, the work must be carried out by the MULTIPLEX
Service Department or a MULTIPLEX Service Centre.

PPM
OPERATING MODE
(
NOT
PCM)
To operate the Graupner transmitter with the M-LINK 2.4 GHz
system you must always set the transmitter to the PPM
operating mode (not PCM!). Exactly the same is true of RF
module compatible JR transmitters.
PPM mode must be set both for normal operations (
Î
14.
) and
for binding mode (
Î
12.
) and range-checking (
Î
13.
).

When you wish to convert back from 2.4 GHz M-LINK operation
to 35, 40, … MHz mode, this is the procedure:
x
Switch the transmitter OFF.
x
Unplug
the
HFMG3 M-LINK 2.4 GHz RF module
:
x
Set the aerial of the
HFMG3 M-LINK 2.4 GHz
RF module
straight.

Now squeeze together the two retaining clips of the RF
module, and carefully withdraw the module up and out
of the transmitter.
