! Please read the instructions before using the product.
! Use the unit only for the intended applications (
! Do not make any modifications of a technical nature to
the RF module.
If any part is damaged, send the RF module to a
MULTIPLEX Service Centre for checking.
! 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. Store it in the protective
anti-static bag at all times (

TATIC ISCHARGE
Electronic devices are vulnerable to damage from
electrostatic charges. This module is fitted with
electrostatically delicate components which can be
affected by the influence of an electrical field or by
static discharge when the unit is touched; the
effective life of the parts may be shortened, or the parts ruined.
That is why the device is supplied in a conductive anti-static bag.
It is essential to observe the following protective measures when
handling vulnerable sub-assemblies:
Before installing the module in the base device, earth any
electrical charge in your body, e.g. by touching a metal
heating radiator.
Open the base unit and hold it by a large area, in order to
dissipate any remaining charge between your body and the
base unit.

ROTECTION OTES
Only now remove the module from the conductive anti-static
bag. Avoid touching any electronic components or solder
pads directly; hold the unit by the edges of the circuit board
only.
If you have to remove the unit from the transmitter, observe
the same safety precautions.
If you need to store the module outside the base device,
always keep it in the conductive anti-static bag. Never allow
it to make direct contact with a conventional container not
designed for the purpose, such as one made of foam, styro-
foam or other plastics.
4. A
PPLICATION
The HFM4 M-LINK 2.4 GHz RF module is approved exclusively
for use in the following MULTIPLEX transmitters:
ROYALpro 7, 9 and 16 M-LINK.
ROYALpro 7, 9 and 12 with firmware Version V3.xx.
ROYALevo 7, 9 and 12, if they have had a software update
(as part of the Update Promotion) to Version V2.xx by
MULTIPLEX Customer Service, and have then been up-
dated to Version V3.xx.
To update the system to firmware Version V3.xx you require
the ROYALpro DataManager PC program (free download
from www.multiplex-rc.de) and the USB PC lead, # 8 5148.
Firmware V3.xx automatically detects whether the transmitter
is fitted with an FM RF module on a conventional frequency
band (35, 40, ... MHz), or the HFM4 M-LINK 2.4 GHz RF
module.

OUNTRY
! Legal note: transmitting apparatus must only be set up

and operated on frequencies / transmission channels which
are approved for the country in which it is to be used.
! Important: in particular countries the module may only
be used within a restricted frequency range.
In certain countries the operation of 2.4 GHz RC systems with
an output power of 100 mW EIRP is only permitted within a
restricted frequency range. For this reason the HFM4 M-LINK
2.4 GHz RF module offers the option of limiting the frequency
range ( 14.).
You can find an overview of the countries affected by this
restriction in the separate sheet entitled "Operating the 2.4 GHz
M-LINK System with Restricted Frequency Range".

M-LINK is a transmission system designed by MULTIPLEX. It
operates on the 2.4 GHz ISM band, and exploits modern FHSS
technology (FHSS = Frequency Hopping Spread Spectrum).
Automatic RF channel management:
With this system it is no longer necessary for the operator to
select the RF channel manually (plug-in crystals, Synthesizer).
2.4 GHz Spread Spectrum systems automatically divide up the
frequency spectrum, and this eliminates the need for conven-
tional frequency monitoring. Same-channel interference (as is
possible on the 35, 40 ... MHz band) is virtually impossible. The
first time the system is used you just have to carry out a simple
binding procedure to link the transmitter to the receiver. From
this moment on the receiver only responds to the signals from
your specific transmitter.
