noise ratio; in this case adjust a higher value with
the key

(5).

5.4 Mute function

The mute function serves for short interruption of the
signal transmission (“throat clearing mode” or “enquiry
mode”) with subsequent immediate readiness for op -
eration without delay.

1) Set the MUTE switch (11) at the lower end of the

microphone to the position MUTE. If required, slide
the safety cap (10) upwards beforehand. The mute
function switched on can also be recognized by the
indication MUTE on the display of the receiver.

2) To continue the signal transmission, set the MUTE

switch to the position OFF.

Note:

In the switch position MUTE there will be no

speech transmission; however, the microphone
will still be in the transmission mode and con-
sume power. Therefore, always switch off the
microphone with the POWER switch (9) [posi-
tion OFF] for longer interruptions.

Replacement Microphone Cartridge

The microphone cartridge (1) can be replaced by the
capacitor microphone cartridge DMC-8000-6 from JTS
which offers a supercardioid characteristic and a wider
frequency range (50 – 18 000 Hz).

1) Unscrew the microphone cartridge (1).

2) Place the replacement microphone cartridge on the

handle in such a way that the 4-pole contacts (12)
of the cartridge and of the handle fit into each other,
then screw the cartridge on the handle.
