6 Operation
To ensure a reliable function of the microphone
unit in an emergency situation, all operating
steps should once be made before the emer-
gency and the necessary adjustments (e. g. vol-
ume conditions) should be optimized. In addi-
tion, check the function regularly.
6.1 Announcement with the hand-held
microphone
For an announcement with the hand-held micro-
phone:
1) Open the door of the microphone unit. For
this purpose, after unlatching the lock, press
down the button PUSH at the left side of the
door so that the lever above it moves
upwards. Seize the lever to open the door. If
the door cannot be opened in case of emer-
gency, break the glass.
2) Take the hand-held microphone (1) from its
support and hold it close to your mouth.
3) Press the talk button (2) and keep it pressed
up to the end of the announcement. Speak
clearly into the microphone.
4) If required, readjust the microphone volume
with the control LEVEL (6). For safety rea-
sons, there is a minimum volume even with
the control turned to the left stop.
5) If the switch COMPRESSION (7) is engaged,
the dynamic power will be limited which
reduces distortions with announcements of
very high volume.
Note: A siren started by an emergency message or an
automatic reproduction of a recording is muted while
using the hand-held microphone.

6.2 Recording of an announcement

1) Open the door of the microphone unit. If the
lock is not latched, press down the button
PUSH at the left side of the door so that the
lever above it moves upwards. Seize the
lever to open the door.
2) Unscrew the two screws of the cover plate
(13) and remove the plate so that the operat-
ing elements of the announcement recorder
are accessible.
3) Slide the switch MODE (14) to position REC.
4) Select the audio source with the switch (19):
"P.T.T." hand-held microphone (1)
"EXT" an audio source connected to the
jacks EXT REC INPUT (26)
5) To delete a recording memorized before,
keep the button "Erase" (21) pressed for 10 s.
6) Adjust the recording level with the control
(23). Turn up the control so far that the LED
"SIG" (22) lights up with the input signal. If the
LED "Clip" lights up, the level is too high. Turn
back the control correspondingly.
If the hand-held microphone (1) is selected
as the audio source, press the talk button (2)
while talking.

7) To start the recording, press the button
"Recording" (20). The LED (17) lights up
while recording.
Note: The switch (15) must be in position "1 Time",
otherwise the recording does not start.
8) To end the recording, press the button
"Recording" again. The LED (17) will extin-
guish.
After reaching the recording time of 60 s
which is possible as a maximum, the record-
ing stops automatically.
Important: Always set the switch MODE (14) to posi-
tion "Play" again after finishing the recording so that in
case of emergency an automatic announcement can be
sent after the recording and an emergency announce-
ment with the hand-held microphone is possible.

6.3 Reproduction of a recording

To check a recording:
1) With the cover (13) removed (
set the switch MODE (14) to position "Play".
2) Select the reproduction frequency with the
switch (15):
"1 Time" one-time reproduction
"Repeat" continuously repeated reproduc-
tion
3) If the reproduction should not be heard via
the amplifier, connect headphones to the jack
(12) [
4) To start the reproduction, press the button
"Play" (16). The LED (17) flashes during
reproduction.
5) Adjust the reproduction volume with the con-
trol (18). For safety reasons, there is a mini-
mum volume with the control turned to the left
stop.
6) To stop the reproduction, press the button
"Play" (16) again.
7) If desired, remount the cover plate (13) as a
protection against unauthorized operation of
the announcement recorder.

6.4 Adjustment of the siren

If an emergency is signalled via the input E / M
TRIGGER (27), first a siren signal is sent to the
amplifier for approx. 8 s before the automatic
announcement starts.
By means of a small screwdriver the volume
of the siren sound can be changed. For safety
reasons there is a minimum volume with the con-
trol turned to the left stop.
The type of the siren can be selected with
the switch SIREN (28):
FLAT
EU
Note: A change of the siren type only becomes effec-
tive after the amplifier is switched on again or after inter-
ruption of the power supply.

7 Indication of Fault
and Emergency
If a fault occurs at the microphone unit, this is
signalled to the amplifier and indicated there. In
addition, the fault relay is switched at the ampli-
fier and thus offers versatile possibilities to call
attention to the fault. In addition to indication via
the amplifier, the LED "Fault" (5) lights up at the
microphone unit, e. g. in case of a defect of the
hand-held microphone or connection cable. If
the signal device (10) is switched on [the switch
(9) is engaged], a pulsating warning sound is
emitted in addition.
A malfunction of the microphone unit proces-
sor is shown by the LED "CPU Error". If the sup-
ply voltage is too low, the LED "Power/Low Volt-
age" (8) flashes.
If an emergency is signalled via the input
E/M TTRIGGER (27), first the selected siren
signal ( chapter 6.4) is sent to the amplifier for
approx. 8 s, before the automatic announcement
starts and it is permanently repeated, if desired.
The indication "EMERGENCY" (3) flashes on
the microphone unit. If the signal device (10) is
switched on at the microphone unit [the switch
(9) is engaged], a permanent warning sound is
emitted in addition. In an emergency the ampli-
fier supplies a switching voltage which may be
used to control emergency priority relays. These
relays bridge the local volume controls in the PA
zones concerned and thus ensure that the emer-
gency announcements can be heard every-
where at maximum volume. All measures for
emergency indication described here stop as
soon as the contacts of the connection E / M
TRIGGER are separated again.
