PA Desk Microphone
GB
1 Applications
This gooseneck desk microphone with chime function has
especially been designed for application in PA systems
and for other applications for which a stable desk micro-
phone is required for announcements (e. g. in office build-
ings, hospitals, stores, etc.).
2 Safety Notes
The desk microphone and the supplied plug-in power sup-
ply unit correspond to the directive 89/336/EEC for elec-
tromagnetic compatibility. The power supply unit addition-
ally corresponds to the low voltage directive 73/23/EEC.
Attention!
The plug-in power supply unit is supplied with hazardous
mains voltage (230 V~). Leave servicing to skilled per-
sonnel only. Inexpert handling may cause an electric
shock hazard. Furthermore, any guarantee claim will
expire if the power supply unit or the desk microphone
has been opened.
The desk microphone and the power supply unit are
suitable for indoor use only. Protect them against dripp-
ing water and splash water, high air humidity, and heat
(admissible ambient temperature range 0 – 40 °C).
Do not set the desk microphone into operation, and
immediately disconnect the power supply unit from the
mains socket if
1. there is visible damage to the desk microphone or to
the power supply unit,
2. a defect might have occurred after a drop or similar
accident,
3. there are malfunctions.
The units must in any case be repaired by skilled per-
sonnel.
For cleaning only use a dry, soft cloth, by no means
chemicals or water.
No guarantee claims for the desk microphone or the
power supply unit and no liability for any resulting per-
sonal damage or material damage will be accepted if
the units are used for other purposes than originally
intended, if they are not correctly connected, operated,
or not repaired in an expert way.
If the desk microphone and the power supply unit are to
be put out of operation definitively, take them to a local
recycling plant for disposal which is not harmful to the
environment.

3 Power Supply
The power supply can be made via the supplied plug-in
power supply unit or via batteries (not supplied). With the
selector switch (1) on the rear side of the unit set the unit
to the type of power supply:
– in case of supply via the plug-in power supply unit
set the switch to the right position "EXT".
– in case of supply via batteries
set the switch to the left position "BATT".
3.1 Plug-in power supply unit
Connect the power supply unit to the jack "DC 3V" (2) and
to a mains socket (230 V~/50 Hz).
If the microphone is not used for a longer period, dis-
connect the power supply unit from the mains as it con-
sumes a low current even if the microphone is switched off.
3.2 Batteries
Remove the battery compartment cover (4) on the lower
side of the unit. Insert two 1.5 V batteries of C size, with the
positive and negative connections as printed in the com-
partment. Close the battery compartment.
Remove the batteries if the microphone is not used for
a longer time (e. g. more than a week). Thus, the unit
remains undamaged in case the batteries should leak.
Do not throw exhausted batteries or defective recharge-
able batteries into the household rubbish but put them
into special waste only (e.g. collector at your retailer).
4 Audio Connection
Connect the jack "AUDIO OUT" (3) via the supplied cable
to a microphone input jack (6.3 mm jack) of an amplifier or
mixer.
5 Setting into Operation
1) Place the supplied windshield (7).
2) To switch on the unit, press the "POWER" button (8).
Then the unit is in stand-by mode. The indicating LED
above the button lights up.
3) To make an announcement, press the button "MIC"
(11). The indicating LED above the button lights up and
a chime sounds to introduce the announcement. After
the chime has stopped, speak into the microphone.
Adjust the volume for the announcement with the con-
trol "MIC" (9): the further the control is turned up clock-
wise, the higher the volume. At the end of the an-
nouncement press the button "MIC" again. The indicat-
ing LED above the button extinguishes and a chime
sounds marking the end of the announcement.
