Range Checking - Multiplex HFMx M-LINK Notice D'utilisation

11. R C
ANGE HECKING
Regular range checks are very important - even when using a
2.4 GHz system - in order to ensure reliable operation of the ra-
dio control system, and to give you a chance to detect sources
of interference in good time. This applies in particular:
• Before the use of new or changed components, or existing
components in a new or modified arrangement.
• Before re-using radio control system components which were
previously involved in a crash or a hard landing.
• If you have encountered problems on a previous flight.
Important:
• Always ask a second person to help you with your range
check, so that one of you can secure and observe the model.
• The range check should only be carried out if there are no
other transmitters switched on at the same time.
Preparing and carrying out a range check:
1. Switch the transmitter OFF and unscrew the 35, 40, ... MHz
transmitter aerial. Ensure that the slide switch on the HFMx
M-LINK 2.4 GHz RF module is in the "2.4 GHz" position
( 9.).
2. Switch the transmitter ON, and press the SET button on the
2.4 GHz RF module within four seconds of switching ON.
Hold the button pressed in until the LED on the HFMx
M-LINK 2.4 GHz RF module lights up constantly.
3. Switch the M-LINK receiver ON, and carry out the range check
as described in the operating instructions supplied with your
M-LINK receiver.
!
Caution: transmitter power is reduced in "range
check" mode! Never attempt to fly a model in range
check mode, i.e. with reduced transmitter power!
4. After the range check, switch the M-LINK transmitter
OFF and then ON again; this switches it back to normal
transmit mode with full range!

In Fast Response mode, which operates at the ultra-rapid pulse
rate of 14 ms, up to twelve servo channels are available. This
reduced pulse rate can cause analogue servos to oscillate or run
jerkily.
If this should occur, it is possible to switch Fast Response mode
OFF on the HFMx M-LINK 2.4 GHz RF module. The frame rate
is then 21 ms.
This is the procedure for switching Fast Response ON or
OFF:
1. Switch the transmitter OFF.
2. You will find two switches on the underside of the HFMx
M-LINK 2.4 GHz RF module. Move the left-hand switch
(switch 1) to change the mode of operation:
•
Switch 1 in ON position (up) = Fast Response ON
•
Switch 1 OFF position (down) = Fast Response OFF
Factory default setting: Fast Response mode OFF.
!
Note: use a small screwdriver (never a pencil!) to operate
the switch!

In particular countries the M-LINK system must not be used
without activating the reduced frequency range approved in that
region ( 4.). For an overview of the countries concerned
please refer to the separate sheet entitled "Operating the 2.4
GHz M-LINK system with restricted frequency range".
This is the procedure for activating the restricted frequency
range:
1. Switch the transmitter OFF.
2. You will find two switches on the underside of the HFMx
M-LINK 2.4 GHz RF module. Move the right-hand switch
(switch 2) to the ON (up) position using a small screwdriver.
Caution: never use a pencil to do this!
3. Now repeat the binding procedure with all the receivers you
wish to use with the transmitter (
!
Note:
If you subsequently decide to operate the M-LINK system
using the maximum possible frequency range:
1. Move the right-hand switch (switch 2) back to the OFF
position (down / default setting).
2. Now repeat the binding procedure with all the receivers
you wish to use with the transmitter (
