Clarson Gard MC is a mic-
roprocessor-controlled sys-
tem operating in open
duplex technology, i. e.
simultaneous bi-directional
voice transmission without
pushing any buttons and
without being influenced by
ambient noises.
Best transmission quality is
achieved when the follo-
wing points are observed:
- Minimum distance bet-
ween table station and
loudspeaker = 1 m.
-Stations with
swan-neck
microphone
require a
speaking distance of ap-
prox. 10 cm.
Stations with
omnidirectio-
nal microphone require a
speaking distance of 1 m.
This adjustment should be
made when installing a
station.
Readjustment might only
be required if a station is
moved to another place.
The station calls itself
when entering code *0
.
Rotate the station by 180
.
In the lower third there are
2 holes: under (1) the volu-
me potentiometer is loca-
ted.
Turn the potentiometer with
a small screwdriver till the
point of feedback is rea-
ched. Then turn it slightly
back till feedback disap-
pears.
