indicator and microphone indicator 2light. In  
this mode, since the number of speakers is not  
limited, the microphones of all the delegates  
units are enabled.  
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 speakers volume is adjusted from the  
SX-M100 Control Unit. To prevent howling,  
nothing is output from the speaker when the  
microphone of the chairmans/delegates unit is  
enabled. Also at the same time, the speaker volume  
of the units on either sides of the unit is  
automatically reduced.  
4 VOL (volume) control

turned off. (The speaker volume is not affected by  
this control.)  
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 delegates units  
are pressed at the same time, the indicator of  
the sixth delegates 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.  
5 Cable with 20-pin multi-connector (for  
the SX-D100A/SX-C100A only)  
Connect to the DELEGATES/CHAIRMANS

System Connection  
This section explains how to connect the system.  
Safety precautions  
Chairmans unit/delegates unit and  
interpreters unit  
Power supply  
Operate the unit only with a power source as  
The SX-M100 Control Unit is provided with four  
DELEGATES/CHAIRMANS UNIT connectors.  
Up to 15 chairmans/delegates units can be  
connected to each of the DELEGATES/  
CHAIRMANS UNIT connectors in serial  
connection. The distance between the control unit  
and the last chairmans/delegates unit should not

specified in Specificationssection.  
Do not drop or place heavy objects on the power  
cord. If the power cord is damaged, turn off the  
power immediately. It is dangerous to use the  
unit with a damaged power cord.  
Disconnect the power cord from the AC outlet by  
grasping the plug, not by pulling the cord.  
Keep foreign objects out of the cabinet  
Dropping flammable or metal objects into the  
cabinet, or spilling liquids onto the cabinet can  
lead to accidents.  
Notes  
Be sure to turn off the power of any units before  
attempting connection or disconnection.  
The desktop type SX-C100A/D100A and the  
desk-mounted SX-C150/D150 are used with this  
system.  
It is not recommended to mix both combinations.  
When the SX-C100A/D100A is used, the SX-  
C700A/C750/D700A/D750 Chairmans Unit/  
Delegates Unit, designed for the simultaneous  
interpretation conference system, can be  
connected to configure this conference system.  
However, after the system power is turned on,  
the microphone indicator and MIC ON/OFF  
buttons of the chairmans unit and delegates unit  
continue to blink for about 3 seconds to inform  
that the SX-C700A/D700A units for  
simultaneous interpretation conference system  
have been connected to the conference system.  
If you turn on the system power before  
connecting the chairmans unit/delegates unit,  
the microphone indicators and MIC ON/OFF  
buttons continue to blink and these units cannot  
be controlled by the control unit. In such a case,  
turn the power off, then back on again.  
When using the DELEGATES/CHAIRMANS  
UNIT connectors of the SX-M100 Control Unit,  
attach the dust caps removed from the 20-pin  
multi-connectors on the control unit to the 20-pin  
multi-connectors on the last unit connected.  
If the 20-pin multi-connector has no dust cap,  
keep it away from metal tools, such as  
In case of malfunctions  
If you notice any unusual sound, smell or smoke,  
turn off the power immediately, disconnect the  
power supply and contact your Sony dealer.  
Cleaning  
Clean the cabinet and panels by wiping with a soft,  
dry cloth. For severe stains, moisten the cloth with  
a small amount of neutral solvent, and finish by  
wiping with a dry cloth. Do not use alcohol,  
benzine, thinner or volatile liquids, as these may  
discolor or damage the cabinet surface.
