Designation Function Application
PULS As soon as a signal is
exceeding the squelch
level, the contact is closing
for a defined time and will
opens then again.
A new activation of the
relay will happen only after
a restart of the system.
The activation is indicated
by the anchor-symbol in the
LC-display (see Fig. 7:
“status of alarm-contact“).
For the connection of a MOB-function (Man
Over Board) of a GPS-receiver Storage
of position at the time of reception. This
function is working on all frequencies.
ELT-ON Contact closes, as soon as
a distress signal (ELT-
modulation) is recognized
by the “selective squelch“
and will open again, if no
more signal is received.
This function is only
available in the airband.
Connection of an alarm bell (if a distress
signal is received) to be activated only in
the airband.

ELT-function.
ELT-PULS
(MOB)
Contact closes, as soon as
the “selective squelch” has
recognized a distress signal
(ELT-modulation) for a
defined time and will opens
then again.
A new activation of the
relay will happen only after
restarting the system.
The activation is indicated
by the anchor symbol in the
LC-display (see Fig. 7:
“alarm contact status“).
As at PULS function, but the system will
react only on signals in the airband.
ATTENTION
Releasing the relay by restarting the
system is to avoid the following
situation:
If the transmitting signal is lost for a
short time, the GPS-position would
be overwritten. This position
wouldn´t be equivalent to the
position of the first alarm (place of
accident at MOB-situation). The first
position would be overwritten
(depending on GPS) and therefore
lost.
