Range Checking - Multiplex HFMG1 M-LINK Manual De Instrucciones

!
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.

OPERATING MODE
Whenever you wish to operate your Graupner mc-18, mc-20 or
mc-24 transmitter with the 2.4 GHz M-LINK system it is essential
to select the PPM operating mode (not PCM!).
This applies to binding mode (
( 15.) as well as for normal operations (

LTERNATING BETWEEN
OPERATION AND
When you wish to convert back from 2.4 GHz M-LINK operation
to 35, 40, ... MHz mode, this is the procedure:
Switch the transmitter OFF, open the transmitter, and
disconnect the transmitter battery (
Undo the 2.4 GHz aerial adapter lead connection.
Disconnect and remove the 2.4 GHz HFMG1 M-LINK RF
module.
Disconnect the LED button lead and the channel expansion
module lead (if present) from the 2.4 GHz RF module.
Push the silicone insulating sleeve over the aerial connector,
and stow the aerial adapter lead carefully inside the trans-
mitter case.
! Caution: the disconnected leads must be deployed
neatly inside the transmitter! You may wish to use adhesive
tape, cable-ties or Velcro (hook-and-loop) tape for this. It is
absolutely essential that you eliminate potential short-
circuits, e.g. due to unsecured leads.
Install the 35, 40, ... MHz RF module.
Connect the transmitter battery (
Screw in the 35, 40, ... MHz aerial.
Reverse the procedure to convert from 35, 40, ... MHz back to
2.4 GHz M-LINK technology.
! Note: you must always remove the 35, 40, ... MHz trans-
mitter aerial (telescopic or short type) before operating the
2.4 GHz M-LINK system!

INDING PROCEDURE
The transmitter and receiver using 2.4 GHz M-LINK technology
must be "bound" to each other once before the system can be
used. This procedure is known as "binding".
! Note:
You will find general information on the subject of binding, and
on fault-finding and correction relating to the binding procedure,
in the operating instructions supplied with your MULTIPLEX
M-LINK receiver.
The binding procedure in detail:
1. Place the transmitter and receiver aerial(s) immediately
adjacent to each other.
2. Switch ON the Graupner mc-18, mc-20 or mc-24 transmitter
with 2.4 GHz M-LINK technology in Binding mode:
Hold the LED button on the transmitter pressed in.
Switch the transmitter ON.
Release the LED button as soon as the LED flashes at a
high rate.
3. Switch the M-LINK receiver ON in binding mode
(see the M-LINK receiver operating instructions):
=> The binding process is now in progress.
4. Once the transmitter and receiver have detected each other,
both units automatically switch over to regular transmit /
receive mode (Normal operations
=> The LED in the transmitter's LED-button flashes
approximately every two seconds.
! Note: the binding process usually only takes a few seconds.

ANGE CHECKING
Regular range checks are very important - even when using a
2.4 GHz system - in order to ensure reliable operation of the
radio 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.
Preparations, carrying out the range check:
1. Select "range check" mode on the Graupner mc-18, mc-20 or
mc-24 transmitter with 2.4 GHz M-LINK technology:
Switch the transmitter ON.
Within four seconds of switching the transmitter ON,
press and hold the LED push-button until the LED itself
glows continuously.
2. Switch the M-LINK receiver ON.
3. Carry out the range check as described in the operating
instructions supplied with your M-LINK receiver.
4. When you have completed the range check, switch OFF
the Graupner mc-18, mc-20 or mc-24 transmitter with
M-LINK technology, and then ON again, in order to
switch back to normal transmit mode with full range!
