7 PRIORITY button and indicator (for the
SX-C100A/SX-C150 only)

the delegate’s units and enable the use of only the

Holding down this button turns on the microphone

8 MIC ON/OFF button and indicator
SX-C100A/SX-C150: Pressing this button turns
the microphone on. The MIC ON/OFF button
indicator and microphone indicator
2 light.
Pressing this button again turns the microphone
off. The indicators go out.
SX-D100A/SX-D150: When the MIC LIMIT ON/
OFF button on the control unit is set to OFF
(the MIC LIMIT ON/OFF button indicator does
not light), pressing this button turns the
microphone on. The MIC ON/OFF button
indicator and microphone indicator
2 light. In
this mode, since the number of speakers is not
limited, the microphones of all the delegate’s
units are enabled.
When the MIC LIMIT ON/OFF button on the
control unit is set to ON (the MIC LIMIT ON/
OFF button indicator is lit), the number of
speakers is limited. Thus, when the MIC ON/
OFF buttons of more than six delegate’s units
are pressed at the same time, the indicator of
the sixth delegate’s unit blinks (for about 3
seconds) to tell the user that the microphone
cannot be enabled since the number of units
whose MIC ON/OFF button is pressed exceeds
six.
The explanations given here apply to both units,
unless noted otherwise, with the exception of
PRIORITY button
7.

3 Speaker
The sound is heard through this speaker when the
microphone is not being used and when an
earphone is not plugged into the earphone jack.
The speaker’s volume is adjusted from the
SX-M100 Control Unit. To prevent howling,

enabled. Also at the same time, the speaker volume
of the units on either sides of the unit is
automatically reduced.
