Only insert batteries of the same type and always
replace all batteries.

If the microphone is not used for a longer period
(e. g. more than a week), remove the batteries.
Thus, the microphone will not be damaged in case
of battery leakage.
1) Unscrew the cap (7) for the battery compartment.
2) Insert two 1.5 V batteries of size AA (R6) with the
positive and negative connections as indicated on
the holder.
3) Place the battery compartment cap straight against
the thread of the microphone body and screw it on.
5 Setting the Microphone into Operation
1) Before switching on the microphone, set the receiv -
er to an interference-free transmission channel
(see instruction manual of the receiver).
2) Then switch on the microphone: Set the POWER
switch (9) at the lower end of the microphone to the
position POWER. If required, slide the safety cap
(10) downwards beforehand. The display (3) will
indicate the transmission group adjusted with the
corresponding transmission channel (in the group
mode), e. g. or the transmission frequency (in
the frequency mode) and a battery symbol (2)
show ing the current charging status of the batteries
in several steps:
fully charged
If the batteries are exhausted (indication
colour of the display on the receiver will additionally
change from green to orange as a warning.
3) The keys (4 – 6) which are slightly recessed are
easily actuated by means of the tip of your thumb.
4) Set the microphone to the same transmission
group and the same transmission channel or the
same radio frequency adjusted on the receiver:
→ chapter 5.1 or chapter 5.2
5) Speak/sing into the microphone. The mute switch
(11) must be in the position OFF, otherwise no
audio signal will be transmitted. The volume level of
the microphone can be readjusted by modification
of the sensitivity → chapter 5.3.
6) The microphone can be locked to prevent acciden-
tal modification of the adjustments or switching off:
→ chapter 5.4.
7) For short interruptions, the signal transmission can
be muted so that no interference will occur → chap-
ter 5.5.
8) The identification ring (8) can be exchanged
against one of the coloured rings supplied. This
allows colour coding of several systems with dif-
ferent radio frequencies.
9) To switch off the microphone after operation, set
the POWER switch (9) to OFF.
