ROBBE HFM12-MX Manual De Uso página 9

Installing the RF module
• Switch the transmitter off.
• Remove the standard RF module from the transmitter.
• Remove the telescopic aerial.
• Set the aerial of the HFM12-MX module straight up.
• Carefully insert the module.
• Set the aerial at right-angles to the transmitter.
Positioning the transmitter aerial
The swivelling transmitter aerial
should be set at right-angles to
the transmitter (see photo), in
order to obtain the best possible
radiation pattern.
Never point the aerial straight at
the model, as the radiated signal
is at its weakest in an imaginary
line extending from the aerial tip.
NOTE:
Do not touch the aerial while you
are operating a model, as this significantly reduces the radiated signal
strength.
Selecting the frequency range
The frequency range of the 2.4 GHz ISM
band differs in certain countries, e.g.
France. If you wish to use the system in
France, you must alter the frequency range.
To select the frequency range you need to
switch the system to "pre-select" mode,
after which the receiver must be "linked"
(bound) again.
GENERAL (universal)
(2405.376 - 2477.056 MHz)
FRANCE
(2407.424 - 2450.432 MHz)
Important note: selecting the frequency range in the 2.4 GHz band
Area of use: EU countries, Switzerland, Norway, Iceland, Russia.
Two different frequency ranges are available in the 2.4 GHz band:
1. 2405.375 - 2477.056 MHz, "General" setting
This frequency range is not uniform (harmonised) in all EU countries, e.g.
in France, for which reason the "CE !" code is required. The manufacturer
is also obliged to "notify" (register) these devices to the relevant national
authorities. In this frequency band different national regulations may
apply to the use of the 2.4 GHz band or the output power due to the lack
of frequency harmonisation.

2. 2407.424 - 2450.432 MHz, "France" setting
This frequency range is harmonised throughout the EU: "CE" code. No no-
tification is required, and no national restrictions apply.
Recommendation:
For the following countries you should select Frequency Range 2 (2400 ...
2454 MHz) "France setting": Austria, France, Russia, Italy, Estonia, Bel-
gium, Luxembourg and Spain (see instructions). In Rumania and Bulgaria
an additional individual licence is required; please contact your authority.
In Norway the use of this frequency band is prohibited within a 20 km ra-
dius of the Ny Aelesund research station.
Operating the module
• Use the transmitter's software to set its modulation to PPM (FM) 18 or
• The module can be switched from twelve to seven channels using
LED STATUS INDICATOR ON THE MODULE
LED green LED red Function/Status
Fail-Safe / Hold-Mode switching
In certain circumstances (interference) the radio link between transmitter
and receiver may fail. For such occurrences you can select either of two
response modes:
1. 'NOR' (normal), or Hold Mode
If interference should occur, the receiver stores the last error-free signals
2. 'F/S' (fail-safe) mode
In this mode the throttle servo runs to a position pre-programmed on the
HFM12-MX module; the setting is also stored in the receiver.
Switching the function on:
• Locate the "F/S RANGE" button on the module, and hold it pressed in
• Watch the LED on the module to determine the set mode: if the green
• Repeating the procedure switches the module back to Hold Mode.
• This is the procedure for setting up the (F/S) positions:
Move the throttle stick to the desired FAILSAFE position, then press the
"Easy Link" button on the receiver to accept the values; hold the button
pressed in until the LED on the receiver glows red once.
NOTE:
During the binding procedure no other FASST or RASST system should
be switched on in the vicinity, otherwise there is a risk that the receiver will
bind to the "wrong" transmitter. Don't set the F/S throttle value too low, as
this could cause the motor to cut out completely when interference
occurs.
IIMPORTANT:
The fail-safe function is permanently pre-set to Channel 3 (throttle) on
the R 607 FS and R617 FS receivers. Due to differences in servo
assignment sequences between Graupner equipment (throttle channel
1) and robbe/Futaba systems (throttle channel 3), channels 1 and 3 are
interchanged in the software of the HFM 12MX module. As a result it is
necessary to swap over the servo outputs 1 and 3 at the receiver (see
table below).
In Helicopter mode no F/S function is available for the throttle channel.
Simply switch to "HOLD" mode.

order to adopt the new setting.
