[SELF-DIAGNOSIS AND TEST MODE]
The TAD-M30 has self-diagnosis mode and test mode. The TAD-
M30 has three test modes: Factory shipment mode, Channel check
mode and FL display tube check mode. The self-diagnosis detects
DSP errors and returns them automatically, and is performed as a
part of the channel check mode. To exit the test mode, press the
POWER button again.

mode and FL display tube check mode. The self-diagnosis detects
DSP errors and returns them automatically, and is performed as a
part of the channel check mode. To exit the test mode, press the
POWER button again.
1. Factory Shipment Mode
When the factory shipment mode is set, the machine settings
return to the factory settings. Set this mode before returning
the repaired machine to the customer. To set this mode, first
remove the AC power cord. Then, while pressing the CURSOR
button and the left CURSOR button ? at the same time,
connect the AC power cord to the power outlet and press the
POWER button. The message “3ch SELF AMP” appears, the
machine is set to the factory shipment mode and the factory
settings are restored.

button and the left CURSOR button ? at the same time,
connect the AC power cord to the power outlet and press the
POWER button. The message “3ch SELF AMP” appears, the
machine is set to the factory shipment mode and the factory
settings are restored.
2. Channel Check Mode
When the factory shipment mode is set, the machine settings
return to the factory settings. The DSP self-diagnosis is
performed as a part of this mode. To perform this self-diagnosis,
first remove the AC power cord. Then, while pressing the
CURSOR button and the right CURSOR button / at the
same time, connect the AC power cord to the power outlet and
press the POWER button. The message “3ch SELF AMP”
appears then the self-diagnosis is performed. If the DSPs are
normal, the message “DSP NO ERROR” appears.
return to the factory settings. The DSP self-diagnosis is

press the POWER button. The message “3ch SELF AMP”
appears then the self-diagnosis is performed. If the DSPs are
normal, the message “DSP NO ERROR” appears.
3. FL Display Tube Check Mode
In this mode, the FL display tubes are checked. To enter this
mode, first remove the AC power cord. Then, while pressing
the DISPLAY button and BASS BOOST at the same time,
connect the AC power cord and press the POWER button.
All the lamps and FL display tubes are turned on and the FL
display tube check is performed. When any CURSOR button
is pressed, the FL display tubes are turned on one after another,
then all FL display tubes are turned on again.
