• 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.

If the unit subsequently operates normally, communication
is resumed.
If this problem occurs frequently, contact your nearest Sony
dealer.
