NSTALLATION NOTES
Receivers contain components which are sensitive to vibra-
tion. You should therefore pack your receiver loosely in foam
or similar material to protect it from vibration - especially with
internal combustion motors.
When installing the receiver, keep it as far as possible (at
least 150 mm) from electric motors, petrol engine ignition
systems and other electronic components such as electric
motor speed controllers, flight batteries, etc. The receiver
aerial should not run immediately adjacent to these compo-
nents.
Keep high-current cables, e.g. those attached to the speed
controller, motor and flight battery, as short as possible.
Electric motors must be effectively suppressed (e.g. using
our suppressor set, # 8 5020). This does not apply to brush-
less motors.
If you are using servo extension leads longer than 50 cm you
should use separation filters (e.g. # 8 5035).
In many cases, receiver interference caused by speed con-
trollers can be reduced by fitting a ferrite ring (e.g. # 8 5035);
the receiver lead attached to the controller should be looped
six or seven times through the ferrite ring as close to the
controller as possible.
Do not alter the length of the aerial. Route the aerial out of
the model and extend it in as straight a line as possible. Do
not leave it coiled up. Do not deploy the receiver aerial
parallel to servo leads, high-current cables or electrically
conductive components (e.g. pushrods). Do not deploy the
aerial inside or over model components which are skinned or
reinforced with conductive materials (e.g. carbon fibre, me-
tallic paints etc.), as they have a shielding effect.
In large-scale models we recommend the use of a whip
aerial. Avoid fitting connectors in the receiver aerial wire if
possible. If unavoidable, we recommend our aerial connector
system: # 8 5233 (plug), # 8 5234 (socket).
Keep to our recommended arrangement of installed compo-
nents (sketches A - C).

ARRYING OUT A
It is very important to carry out regular range checks to ensure
that the radio control system works reliably. These checks also
allow you to detect problems and sources of interference in good
time. This applies in particular when:
You are using new or altered components, or you have
changed the arrangement of components in the model.
You are using radio control system components which were
involved in a previous hard landing or crash.
Irregularities or problems have arisen during previous flights.
Important:
Always carry out the range check with the help of a friend
who can hold and watch the model (vehicles and boats on
their running surface).
For a range check install the telescopic transmitter aerial but
leave it completely collapsed.
Don't use a helical stub aerial for range-checking!
Ensure that no other transmitter is switched on while you are
carrying out the range check, even on other channels.
The range of the RX-7-SYNTH IPD, RX-7-SYNTH DS IPD and
RX-9-SYNTH DS IPD compact receiver with transmitter aerial
collapsed down to a single segment should be at least 80 m. We
recommend that you disable the IPD filter for range-checking, so
that interference and irregularities are not suppressed. You have

reached the range limit when the servos begin to jitter and move
uncontrollably, and no longer respond clearly to control
commands. If your transmitter has an automatic servo test
program, we recommend that you set this up for one control
function, e.g. rudder, for the range check, as this guarantees
even servo movement, and makes it easier to see when the
receiver no longer responds correctly to control commands.
Important:
Carry out the initial range check with the motor or engine
stopped. Repeat the check with the power system operating (all
throttle settings): the range should not be significantly reduced. If
it is much lower, seek out and eliminate the cause of the
problem (motor interference, arrangement of the receiving
system components and power supply, vibration, etc.).

ISPOSAL OTES
Electrical equipment marked with the crossed-out
waste bin symbol must not be discarded in the do-
mestic waste; it should be disposed of via the appro-
priate specialised disposal system.
In the countries of the EU (European Union) electrical
devices must not be discarded via the normal domestic
waste system (WEEE - Waste of Electrical and Electronic
Equipment, Directive 2002/96/EG). You can take your unwanted
equipment to your nearest public collection point or recycling
centre, where it will be disposed of in the proper manner at no
charge to you.
By disposing of your old equipment in a responsible manner you
make an important contribution to the safeguarding of the
environment!
