AFETY NOTES
!
Please read the instructions before using the product.
!
Use the unit only for the intended applications ( 4.).
!
Never touch any soldered joint, electronic component
etc. with a metallic object of any kind, as this could
cause a short-circuit.
!
Disconnect the transmitter battery from its socket before
carrying out any work inside the transmitter!
For information on disconnecting and re-connecting the
transmitter battery please refer to the operating
instructions supplied with your Graupner transmitter.
!
Do not make any modifications of a technical nature to
the RF module.
If any component should be damaged, always have it
checked by a MULTIPLEX Service Centre.
!
Do not touch any components on the RF module when
inserting or removing it.
!
When the RF module is not installed in a transmitter,
protect it from mechanical load (vibration, shock,
distortion, ...) and damp. Place the RF module in the
protective ESD bag for storage ( 3.).
3. ESD
NOTES
Electronic devices are susceptible to damage
from static electronic charge, and both the trans-
mitter and the sub-assemblies mentioned in these
operating instructions are fitted with components
which are electrostatically sensitive. These parts
may be ruined, or their effective life shortened, by the effect of
an electrical field, or by static discharge (potential equalization).

Operating Instructions

HFMG4 M-LINK 2.4 GHz RF Module
# 4 5617
2.4000 GHz ... 2.4835 GHz
Restricted frequency range:
2.4000 GHz ... 2.4540 GHz
2.4 GHz FHSS M-LINK system
MULTIPLEX-LINK
100 mW EIRP
approx. 50 mA
- 15 °C ... + 55 °C
approx. 64.0 x 55.0 x 12.5 mm
(excl. 2.4 GHz aerial unit,
excl. LED button)
approx. 33 g
(RF module including
2.4 GHz aerial unit
and LED button)
For this reason the 2.4 GHz HFMG4 M-LINK RF module is
supplied packed in a conductive ESD protective bag.
It is essential to observe the following protective measures
when handling electrostatically sensitive sub-assemblies:
 Before fitting or removing such sub-assemblies from the
base device, equalize the electrical potential between your-
self and your environment (typically by grasping an earthed
radiator).
 Open the base unit, and touch a large area of it in order to
equalize the potential with the base unit.
 Only now remove the RF module from the conductive ESD
protective bag. Avoid directly touching electronic compo-
nents or soldered joints. Hold sub-assemblies by the edges
of the circuit board only.
 If you store the module outside the transmitter, keep it in the
conductive ESD bag; it must not come into direct contact
with a conventional, non ESD-compatible container made of
foam, styrofoam or plastic.

PPLICATION
The 2.4 GHz HFMG4 M-LINK RF module is approved exclu-
sively for use in the following Graupner transmitter:
 Graupner mc-32

PECIAL CHARACTERISTICS
 Simple installation:
The uncased HFMG4 M-LINK is designed to be installed and
connected inside the transmitter. The aerial lead with screw-
fitting base and the LED button are installed in two vacant
switch wells. All that remains then is to screw the 2.4 GHz
transmitter aerial into its socket.
 Integral buzzer:
If a telemetry-capable M-LINK receiver is used, the trans-
mitter emits an audible warning when the receiver battery
voltage falls to a dangerous level.
 LED button:
Externally accessible, functions as status indicator, binding
button and range-check button.
 Prepared for use with the MULTIPLEX Telemetry-Display
(# 4 5182):
If the system includes a telemetry-capable receiver and
external sensors, up to sixteen telemetry values can be
generated and shown on the Telemetry-Display, including
visual and audible warnings.
 Operates directly 12 channels. It is possible to expand the
transmitter by a further four channels using the channel
expansion module (# 7 5810). In Graupner terminology this
typically corresponds to eight additional channels! All the
channels are fully proportional, of equal value, and are
transmitted at the same high speed, although it is not
possible to program these four supplementary channels.
The channel expansion module is connected to the 2.4 GHz
HFMG4 M-LINK RF module. Up to four transmitter controls
(available as accessories) can be connected to this module.
 Switchable between 14 ms servo frame rate (Fast Response)
and 21 ms; can also be switched between maximum and
restricted frequency range (France mode).
 Update-capable:
The 2.4 GHz HFMG4 M-LINK RF module can be updated at
any time using the MULTIPLEX Launcher PC program, and
is therefore future-proof. MULTIPLEX Launcher is available
as a free download from www.multiplex-rc.de. To carry out
an update you also require the UNI USB PC lead (# 8 5149).
