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-M700A Control Unit is provided with four
DELEGATE’S/CHAIRMAN’S UNIT connectors and
two INTERPRETER’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).
A total of seven interpreter’s units can be connected
to the two INTERPRETER’S UNIT connectors. For
example, three units can be connected to one
connector and four units to the other. The distance
between the control unit and the last interpreter’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.
•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 INTERPRETER’S UNIT
connectors (20-pin multi-connector) and
DELEGATE’S/CHAIRMAN’S UNIT connectors
(20-pin multi-connector) of the control unit, attach

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
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 channel of the language
to be monitored cannot be
selected by the CH selector.
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
The chairman’s unit/delegate’s
units for a simultaneous
interpretation conference
system, SX-C700A/D700A/
C750/D750, and those for a
conference system, SX-C100A/
D100A/C150/D150, 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 earphone may be
disconnected.
• The mode is that where the
number of speakers is limited.
• The PRIORITY button is held
down by the chairman.
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.
Remedies
To configure the simultaneous conference system, use only
SX-C700A/D700A/C750/D750 units.
• 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.
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.
