[Error indicator status]
Possible cause and remedy
Power off
AC adapter is disconnected.
→ Ensure the connection of power supply.
CPU error (CPU hang-up)
→ Contact your TOA dealer.
Data write error
Writing data failed because the unit's power is shut off or
other trouble occurs during data write or firmware update.
→ Contact your TOA dealer.
Firmware exception handling occurrence
→ Push the front-mounted Reset button to restart the unit
operation.
If this happens frequently, contact your TOA dealer.
Communications-related errors on network and control
Causes may be the following: Power-off or network
disconnection of the unit set to be controlled, duplicate
control (busy), NX-100/100S setting errors (impossible
control or communications settings), and network
equipment setting errors.
→ Establish a connection to the unit to be controlled, or
change settings of individual equipment.
Packet collision occurrence
The NX-100/100S and the connected network equipment
are in half-duplex communications, and collision occurs.
This may cause intermittent sound when audio signals are
transmitted.
→ It is preferable to use the NX-100/100S in full-duplex
communications.
Network disconnection
LAN cable is disconnected or network equipment is turned
off.
→ Ensure each connection to the network equipment.
Excessive audio signal input (Distorted output signal)
Audio signal level applied is excessively high.
→ Set the input volume control and the input level selection
switch appropriately.

STATUS ERROR RUN
No audio signal input
If this happens though the Audio input terminal is
connected to equipment, the cause may be the following
case: the external equipment is turned off, or its
connection cable is disconnected, or the NX-100S input
volume control is fully turned down.
→ Ensure the connection and power of external equipment,
and the NX-100S volume control adjustment.
