2) To unlock the battery holder (7), press the lock (6)
in arrow direction backwards.
3) Remove the battery holder up to the stop (fig. 4)
and insert two 1.5 V batteries of size AA (R6) with
the positive and negative connections as indicated
on the holder.
4) Slide back the battery holder so that it locks into
place.
5) Place the microphone cartridge onto the handle in
such a way that the 4-pole contacts (5) of cartridge
and handle engage, then screw the cartridge onto
the handle.

5 Setting into Operation

1) To switch on, set the switch POWER (4) at the
lower end of the microphone to ON. The display (2)
indicates the transmission channel adjusted and a
battery symbol indicating the current charging sta-
tus of the batteries in several steps:
fully charged
2) To remove the plastic cap (3), slightly press down
the grooved latch on the rear side of the cap and
remove the cap.
Then the control part with the three adjusting
keys (8, 9, 10) is accessible (fig. 5). To actuate the

may be used.
3) Adjust the transmission channel for the microphone
→ see chapter 5.1. Switch on the receiver and
adjust it to the same channel → see operating
instructions of the receiver.
Switch on the audio unit (mixer or amplifier)
connected to the receiver.
4) Speak/sing into the microphone. The volume level
of the microphone may be readjusted by modifying
the sensitivity → see chapter 5.2.
5) The microphone may be locked to prevent acciden-
tal change of the adjustments or accidental switch -
ing off → chapter 5.3.
