Setting Up the System

Precautions

Safety precautions

Power supply

• Operate the unit only with a power source as specified in “Specifications” section.

• 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.

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.

System Connection

This section explains how to connect the system.

Chairman’s unit/delegate’s unit and interpreter’s unit

The SX-M100 Control Unit is provided with four DELEGATE’S/CHAIRMAN’S UNIT connectors. Up to 15 chairman’s/delegate’s units can be connected to each of the DELEGATE’S/ CHAIRMAN’S UNIT connectors in serial connection. The distance between the control unit and the last chairman’s/delegate’s unit should not exceed 60 meters (196.8 feet).

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 SXC700A/C750/D700A/D750 Chairman’s Unit/ Delegate’s 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 chairman’s unit and delegate’s 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 chairman’s unit/delegate’s 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 DELEGATE’S/CHAIRMAN’S 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 screwdrivers to prevent the connector being inadvertently shorted.

Troubleshooting Guide

Should a problem arise in your system, check the system while referring to the instructions in the table below. If the system continues to malfunction after applying the following checks and remedies, contact your nearest Sony dealer. The system indicates the problem by lighting the microphone indicator and MIC ON/OFF button of chairman’s/delegate’s units.

Lighting of the microphone indicator and MIC ON/OFF button of the chairman’s unit/ delegate’s unit

The indicator and button blink for a few seconds when the POWER switch of the control unit is set to ON.

The indicator and button of the chairman’s/ delegate’s units continue to blink, after the power switch of the control unit is set to ON.

After the unit has been operated for a while after the power is turned on, the unit’s indicator and button start blinking and do not go out, even after a few seconds.

The volume of the earphone cannot be adjusted by using the VOL control.

The indicator and button blink and the microphone is disabled even if the MIC ON/OFF button is pressed.

Possible cause Remedies

The chairman’s unit/ delegate’s units for a conference system, SXC100A/D100A/SX-C150/ D150, and those for a simultaneous interpretation conference system, SX-C700A/ D700A/SX-C750/D750, have been connected.

The units whose indicator and button are blinking cannot be controlled by the control unit and cannot be used in this system.

A communication error has occurred.

The earphone may be disconnected.

• The mode is that where the number of speakers is limited.

• The PRIORITY button is held down by the chairman.

The SX-C700A/D700A/SX-C750/D750 can be used. However, same sound is output from channel 1 to channel 6.

• When the indicator and button of units subsequent to the 16th unit of the units connected to one DELEGATE’S/ CHAIRMAN’S connector of the control unit blink: – More than 16 units cannot be connected to one

DELEGATE’S/CHAIRMAN’S connector in series. Disconnect the 16th unit and subsequent units.

• Even though the number of connected units is less than 16, the indicators of some of the connected units blink: – The first unit whose indicator and button are blinking may

be defective, or the connecting cable may be broken. Disconnect the first unit of those whose indicator and button are blinking. When the indicator and button of the subsequent units stop blinking and go out, it indicates that the disconnected unit was defective. Remove it from the system or replace it with a functioning unit. When the indicator and button continue to blink even after removing the first unit, the connecting cable is probably broken. Replace the connecting cable linking the first unit whose indicator and button are blinking and the unit immediately prior to that unit.

• Even though the number of connected units is less than 16, the indicator and button of some of the connected units blink: – The unit whose indicator and button blink is defective.

Disconnect it from the system or replace it with a functioning unit.

Briefly turn the power off, then back on again. If the unit subsequently operates normally, communication is resumed. If this problem occurs frequently, contact your nearest Sony dealer. If the indicator and button continue to blink just after the power is turned on again, a problem described above may have occurred. Proceed as described above.

Insert the earphone plug into the earphone jack surely.

• Wait until the speaker finishes speaking. Press the MIC ON/OFF button again.

• Wait until the chairman releases the PRIORITY button.
