Re. 7.: the (STATUS) LED lights up when you switch on, but
does not flash: is the transmitter switched on? Is the trans-
mitter set to M-PCM? Is a different transmitter set to the
same channel?
9.2 The functions of the SET button
If you hold the SET button on top of the receiver pressed in
when switching it on, the automatic RF channel search (
commences when you release the button.
In reception mode three supplementary functions can be
triggered using the SET button. They are selected according to
the length of the button-press:
1. Store error counter or Fail-Safe settings
Hold the SET button pressed in for 0.5 to 1 second (
9.6).
2. Test receiver Diversity function
Hold the SET button pressed in for 2 to 10 seconds (for more
details see the instructions for the Diversity lead for RX-
SYNTH M-PCM receiver # 8 5070).
3. Receiver reset to factory default settings
Hold the SET button pressed in for more than 10 seconds
( 9.5).
The (STATUS) LED displays time markers to indicate the length
of the button-press while you are holding the SET button
pressed in:

9.4 Hold and Fail-Safe
The effect of the Fail-Safe setting is to cause the servos to run to
previously defined positions after a Hold period when inter-
ference occurs.
9.4 /
In the default state the receiver's Fail-Safe circuit is switched off.
It is not activated until you define the Fail-Safe settings for the
first time. Fail-Safe is invoked using the SET button on the
receiver, or from the transmitter (see transmitter operating in-
structions). If you wish to disable Fail-Safe again, the receiver
must be reset to its factory default settings (Reset).
Note: always activate Fail-Safe!
For reasons of safety we recommend that you always activate
Fail-Safe, and ensure that your chosen Fail-Safe settings result
in the model entering as safe a condition as possible (e.g. motor
to idle / electric motor off, control surfaces neutral, airbrakes
extended, tow-release open, ...).
Setting the Fail-Safe positions
1. The (STATUS) LED must indicate no errors.
If it indicates errors: switch the receiver OFF, then ON again.
2. Move all the servos (and the speed controller) to the desired
positions, then hold the SET button pressed in for 0.5 to 1
second: the servo positions are stored, the (STATUS) LED
flashes the confirmation signal once (LED code 5,
After sixteen seconds in Fail-Safe mode the servos are no
longer fed a signal (default setting; this time can be altered using
the MULTImate or a PC
digital servos (see instructions) then become "soft", and modern
speed controllers switch themselves off. However, some digital
servos remain "hard", and hold their last position.
Fail-Safe mode terminates as soon as the receiver picks up
error-free signals again.
The Fail-Safe function can be activated or disabled for each
servo separately using the MULTImate or the RX-SYNTH Data-
Manager (PC application). Example: throttle to idle / off, all other
servos = Hold.
Testing the Fail-Safe settings
Move the transmitter sticks to positions other than the selected
Fail-Safe settings, then switch the transmitter OFF. When the
Hold period has elapsed, the servos should run to the Fail-Safe
settings you previously defined.
The Fail-Safe settings must always be checked and adjusted /
updated if necessary. For example, if you install the receiver in a
different model, or if you accidentally misuse the receiver.
Checking the Fail-Safe function:
When you are checking the Fail-Safe function with the trans-
mitter switched off, be sure to operate the receiver only briefly,
as there is a danger that the motor could burst into life - injury
hazard!
9.5 Reset to factory default settings
It is possible to reset the receiver settings to the factory default
values. If you do this, all your settings (e.g. RF channel, Fail-
Safe values) will be lost.
Hold the SET button pressed in for at least ten seconds. The
(STATUS) LED helps you with the timing: when you press the
button, the (STATUS) LED goes out; it then comes on again
after two seconds, and goes out again after ten seconds.
