The FAIL-SAFE settings are only stored if the IPD filter is
active, and if no errors are displayed:

PPM 9 PPM 12), you must re-set the FAIL-SAFE positions!

The FAIL-SAFE settings must always be checked and brought
up to date if, for example, you install the receiver in a new
model, or make an accidental mistake in programming the
receiver ( 13.4 ). 13.4 13.4 13.4
•
The maximum FAIL-SAFE duration is limited to 15 seconds.
After this the servo signal is switched off ⇒ the servos be-
come "soft", an electric motor speed controller switches off
the motor in the absence of a signal.
This eliminates the danger of jammed control surfaces stalling
the servos (e.g. after a crash), which would usually wreck
them.
•
If FAIL-SAFE has not been activated, servos with their own
HOLD or FAIL-SAFE function (e.g. MULTIPLEX mc and mc/V2
series digital servos) do not become "soft" after the HOLD pe-
riod has elapsed.

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.

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
•
Hold the button pressed in again for > 2 seconds (see above)

In the interests of safety the IPD filter should only be switched
off for range checks or other experimental purposes. Normal
operations should always be carried out with the IPD filter acti-
vated.

ECEIVER
The receiver settings can be switched back to the factory default
values. All settings (RF channel, FAIL-SAFE settings) are lost when
you do this, and the receiver acts like a brand-new receiver, fresh
from the factory.

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 trans- 10 10 10
mitter signal. For this to work an RF channel must have been set
previously.

RROR COUNT
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:
1,6 sec
LED Code 6
1,6 sec
LED Code 7
1,6 sec
LED Code 8
In our experience the errors described here occur during virtually
all 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 glitch counter helpful as a
means of detecting changes in good time, and as an indicator of
possible causes of interference and other problems, e.g. short-
comings in the power supply circuit, interference caused by the
power system, electrical "noise" caused by metal-to-metal
contact, etc.
16.1 16.1 16.1 16.1 Low voltage error count Low voltage error count Low voltage error count Low voltage error count
The counter counts the seconds during which the voltage (after
the battery backer) falls below 4.4 V, either briefly or constantly.

The counter counts the seconds in which the field strength col-
lapses. Instances of constant low field strength (transmitter off)
are not counted.
16.3 Signal interference error count 16.3 Signal interference error count
16.3 16.3 Signal interference error count 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: Note: Note: Note:
If the voltage falls below 3.0 V for a long period, the receiver's
processor will restart. If this should happen, the values for all
three error counters are lost.

If the IPD filter is switched off, the receiver does not count the
signal errors, and no errors are displayed. Errors are only
displayed again when the IPD filter is re-activated (
