OTES
Protect your receiver from vibration, especially in models
powered by an internal-combustion engine (e.g. pack it loosely
in foam).
Locate the receiver at least 150 mm away from electric mo-
tors, petrol engine ignition systems and any other electronic
components such as speed controllers for electric motors and
drive batteries. Keep the aerial away from these components.
Install the receiver in the model in such a way that the aerial
is as far away as possible from all conductive materials.
If your model’s fuselage consists of conductive materials (e.g.
carbon fibre), then the aerial must be installed in such a way
that the active part of the aerial (the final 30 mm) is located
outside the model.
Do not deploy the receiver aerial inside or on model com-
ponents which are laminated or reinforced with electrically
conductive materials (metal foil, carbon fibre, metallic paints
etc.), as they have a shielding effect.
Do not shorten or extend the aerial or the aerial feed cable.
Never attempt to replace or repair the aerial or aerial cable!
Do not deploy the aerial parallel to servo leads, high-current
cables or electrically conductive parts (e.g. pushrods).
Keep to the recommended installed arrangements (
20.
,
sketches A - C)!
High-current cables, e.g. those attached to the speed con-
troller, motor and flight battery, should be kept as short as
possible.
If you are using a diode-based battery backer, always install a
PeakFilter (
# 8 5180
).
Reception quality can be optimised by fitting a special ferrite
ring (
# 8 5146
) or suppressor filter lead (
# 8 5057
) in the speed
controller cable. It is also advisable to fit effective suppressors
to conventional (brushed) electric motors (not brushless types)
(e.g. use the suppressor set
# 8 5020
).

HECKING
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 enable you 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.
If possible, carry out the range check when no other trans-
mitters are operating.
Carrying out the range check:
1. Select “range-check mode” on your transmitter (see the
operating instructions supplied with the transmitter or RF
module).
There must be line-of-sight connection between the trans-
mitter and receiver aerials (i.e. the model) during the range
check.
Keep the transmitter and the model about one metre above
ground during the range check.
2. When checked with reduced transmitter power, the range of the
RX-5/7 M-LINK
receiver must be 40 metres. You have reached
the range limit when the servos start to move jerkily.
If your transmitter features an automatic servo test facility,
we recommend that you activate it for one control function
(e.g. rudder). This sets up a steady movement of the servo,
and enables you to detect the limit of range clearly.
Important:
Carry out the first range check with the motor switched off. Turn
the model into all attitudes, and attempt to optimise reception by
changing the position of the two aerials.
For the second range check, run the motor at varying speeds
and check that the effective range is not significantly reduced. If
there is a marked reduction, locate and eliminate the cause of
the interference (caused by the motor, the arrangement of the
receiving system and power supply, vibration, etc.).

XCHANGING THE
A
ERIALS
If you require longer or shorter aerial feed cables, please contact
the MULTIPLEX Service Department or any MULTIPLEX Ser-
vice Centre, as they stock cables of different lengths, and will
gladly quote an individual price for modifying your receiver to
professional standards.
!
Caution: never attempt to exchange the aerial yourself!
Changing the aerial to a professional standard requires
special tools as well as appropriate expertise. Ignoring this
warning may have an adverse effect on the receiver’s
reception quality.
!
Caution: if the active part of the aerial (the final 30 mm)
should be damaged, the aerial must be replaced by the
MULTIPLEX Service Department or a MULTIPLEX Service
Centre; this also applies if the aerial feed cable is damaged.
