6. Binding the receiVer

The transmitter transmits an encrypted code which identifies
it unambiguously. The encoding facility renders "channel clas-
hes" impossible.
The transmitter code can be stored in the receiver; once this
has been carried out, the receiver only responds to this one
transmitter, i.e. the components are "bound" to each other.
From this moment on the receiver only accepts the signals
of the transmitter with this specific code - regardless of which
transmitters log onto the ISM band subsequently.
By its very nature, this fixed assignment between transmitter
and receiver offers the best possible pre-conditions for highly
effective suppression of interference signals (far better than is
possible with conventional RC systems), since a digital filter
is employed which is capable of allowing through only those
control signals generated by the bound transmitter.
Since the transmitter code is stored in the receiver, the trans-
mitter can be used to operate as many receivers as you like. If
you wish to use a receiver which is bound to a different trans-
mitter, a simple button-press erases the receiver's memory,
making it possible to store the code for the new transmitter.
1 Switch the transmitter on.
Bring the transmitter and receiver close together (approx.
2
50 cm).
3 Switch the receiver power supply on.
4 Locate the "SW" button on the recei-
ver, and hold it pressed in for about
two seconds to "bind" the compon-
ents.
Pressing the "SW" button automatically stores the transmitter's
individual code number in the receiver. This binding procedure
causes the receiver to respond only to the signals from this
specific transmitter, thereby very effectively suppressing inter-
ference and the influence of other transmitters. Several recei-
vers can be "bound" to the same module.
If the binding process is to involve a different module, press the
SW button again after switching on.

6.1 range-checKing (pOWer-dOWn mOde)
In this mode the output of the RF section is reduced in order to facilitate
range-checking. Locate the push-button at bottom left of the transmitter;
Power-Down mode is selected by holding this button pressed in while
you switch the transmitter on. The LED now flashes red at a high fre-
quency to indicate that the transmitter is set to low power output.
first switch the model on without the power system active.
• Slowly walk away from the model, operating one control surface func-
tion slowly but continuously.
• While you are walking away, watch the corresponding control surface
on the model, checking for the moment when it falters or stops. It can
be helpful to ask a friend to watch the model for you as you walk away,
holding the transmitter.
• As the distance increases, occasionally turn the transmitter through
45° in both directions, to simulate different aerial positions relative to
the model.
• In Power-Down mode the radio range should be about fifty paces.
• If this initial range-check is successful, repeat the check with the motor
running (caution: secure the model).
• The range now obtained should only be slightly shorter (around 20%).
If there is a significant reduction, then some part of the power system
is causing interference to the receiver. You can usually remedy this by
checking all the measures described above.
• Power-Down mode remains active as long as the button is held pressed
in.
• If you wish to call up Power-Down mode again, you must switch the
transmitter off and then on again. Power-Down mode can then be swit-
ched on as described above.
cautiOn:
Never operate a model with the transmitter set to Power-Down mode
(for range-checking).
For safety reasons it is not possible to carry out a second range-check
if the transmitter has already been transmitting at full power. If you wish
to do this, you must first switch the transmitter off, then on again. This
feature is designed deliberately to prevent you switching to range-check
mode when you are operating a model.

7.2 removing the transmitter back panel
The back panel of the transmitter is secured to the case using
four cross-point screws.
Opening the back panel:
• Remove the transmitter batteries.
• Unscrew the four screws in the back panel using a suitab-
le screwdriver.
• Lift off the back panel.
Closing the back panel:
• Carefully replace the back panel on the rear of the trans-
mitter case.
• Fit the four screws and tighten them to secure the back
panel.
• Install the batteries, then close the battery compartment.
