WITCHING OFF THE
The IPD filter ( 12.) can be switched off if necessary. In this
mode the receiver operates like a conventional FM/PPM unit, i.e.
the signals picked up are passed directly to the servos (etc.).
This can be useful, for example, to locate sources of problems to
the receiver caused by the power system, or the arrangement of
the receiving system components. The filter should always be
switched off for range-checking, so that it does not filter out any
interference (undesirable in this case). Changes can then be
made as required.
Sequence:
1. Switch the transmitter ON, then switch the receiver ON. The
LED flashes:
1,6 sec
LED Code 3
2. Press the button (the LED goes out), and hold it pressed in
until the LED comes on again (after about 2 seconds. The
LED then flashes as follows:
1,6 sec
LED Code 4
Exception: RX-SYNTH set-up lead: In this case the LED
does not glow when the button is pressed in!
You can re-activate the IPD filter by either of the following
methods:
Switch the receiver OFF, then ON again
or
Hold the button pressed in again for >2 seconds (see above)
! Note: do not switch the IPD filter OFF except for test pur-
poses
In the interests of safety the IPD filter should only be switched
OFF for range checks or other experimental purposes. Normal
driving operations should always be carried out with the IPD
filter activated.
15. R RESET
ECEIVER
The receiver settings can be switched back to the factory default
values. All settings (e.g. RF channel, FAIL-SAFE settings) are
lost when you do this, and are reset to the factory defaults.
Sequence:
1. Switch the transmitter ON, then switch the receiver ON. The
LED flashes:
1,6 sec
LED Code 3
2. Press the button and hold it pressed in until the LED goes
out - after about 10 seconds. The LED now flashes the
confirmation signal:
1,6 sec
LED Code 5
The signal output is switched off after you carry out a RESET.
The receiver can only be used again after switching it OFF, then
ON again ( 10.).
A RESET can also be triggered without a transmitter signal. For
this to work an RF channel must have been set previously.

RROR COUNTER
The receiver features three internal error counters for the
following errors:
Low voltage
Reception blind spots (severe field strength fluctuations)
Signal interference
The LED displays the sum of the errors in the three error
counters as soon as an error is detected:

In our experience the errors described here occur during most
flights. Signal errors in particular occur quite often with FM/PPM
transmission. Generally speaking, the operator does not even
notice them, but the highly sensitive signal error counter still
registers them. After a few sessions, with subsequent analysis of
the error count, you will find the error counter helpful as an early
method of detecting irregularities in operating the model, in order
to eliminate problems (e.g. in the power supply circuit, inter-
ference caused by the power system, electrical "noise" caused
by metal-to-metal contact, etc.
16.1 Low voltage error count
The counter counts the seconds during which the voltage falls
below 4.4 V, either briefly or constantly.
16.2 Field strength fluctuations error count
(reception blind spots)
The counter counts the seconds in which the field strength
collapses. Instances of constant low field strength (transmitter
off) are not counted.
16.3 Signal interference error count
The counter records the seconds in which the signal packet is
not within the prescribed format, e.g. too many, too short or too
long servo signals.
If voltage falls (voltage collapse), reception blind spots and
signal interference are not counted. If a blind spot occurs, signal
interference is not counted. However, signal errors often occur
before or after a collapse in field strength or voltage, and these
are counted.
! Note: re-starting the processor
If the voltage falls below 3.0 V for a longer period, the receiver's
processor will restart. If this should happen, the values for all
three error counters are lost.
! Note: power-on delay
The error counters only start operating after a delay of 20 se-
conds after the receiver is switched on.
! Note: error counter when the IPD filter is OFF
If the IPD filter is switched off, the receiver does not count the
signal errors, and no errors are displayed. Errors are only dis-
played again when the IPD filter is re-activated (

IAGNOSIS MODE
Diagnosis mode can be helpful when you need to carry out
adjustments on the model, but the transmitter is not to radiate an
RF signal. The transmitter (MULTIPLEX transmitter with multi-
function socket) is connected directly to the receiver using an
MPX switch harness with charge socket and a diagnosis lead,
# 8 5105. The switch harness must be connected to the socket
marked "B/D" (D = Diagnosis).
For MULTIPLEX PROFI CAR series transmitters the Diagnosis
Adaptor, # 8 5110, is available. This is plugged into the trans-
mitter in place of the RF module. The other end of the lead is
connected directly to the receiver socket marked "B/D" by
means of the UNI connector.
When you switch the system on, the receiver detects that the
diagnosis lead is connected. For this reason the transmitter must
be switched on before the receiver. The signal packet is re-
ceived directly from the transmitter via the diagnosis lead, and
not via the RF link.
