Display
provided when Self-Diagnostic Function started
The display is as described below depending on the situation when the last time the power to this unit is turned off.
When the power is turned off by usual operation:
The FL display of this unit displays “NO PROTECT” then the main menu (sub-menu “1. ANALOG BYPAS” of main menu 1 BYPASS) a few seconds later.
The display is as described below depending on the situation when the last time the power to this unit is turned off.
When the power is turned off by usual operation:

When the protection function worked to turn
off the power
The FL display of this unit displays the data of protection function which worked at that time then the main menu (sub-menu “1.
ANALOG BYPAS” of main menu 1 BYPASS) a few seconds later.
Note: At that time if you reactivate the self-diagnostic function after turning off the power once by pressing the “MAIN
ZONE ON/OFF” key, “NO PROTECT” will be displayed because that situation is equal to “1. When the power is turned off by usual operation:” described above.
However the protection function history is stored in a backup memory. For details, refer to main menu 21 PROTECTION HISTORY.

When
the protection function worked due to excess current
Cause: An excessive current
flowed through the power amplifier.
Supplementary information: As current of the power amplifier is detected, the abnormal channel can be identified by
checking the current detect transistor.
Turning on the power without correcting the abnormality will cause the protection function to work immediately and the
power supply will instantly be shut off.
Supplementary information: As current of the power amplifier is detected, the abnormal channel can be identified by
checking the current detect transistor.
Turning on the power without correcting the abnormality will cause the protection function to work immediately and the
power supply will instantly be shut off.
Note: Applying the power to this unit without
correcting the abnormality can be dangerous and cause additional circuit
damage. To avoid this, if protection function has been activated 3 times
continuously, the power will not turn on even when the “MAIN ZONE ON/OFF”
key is pressed. In order to turn on the power again, disconnect the power
cable of this unit from the AC outlet once and then reconnect it again.
# The output transistors in each amplifier channel should be checked for damage before applying power of this unit.
Amplifier current should be monitored by measuring DC voltage across the emitter resistors for each channel.

When
the protection function worked due to a short between speaker terminals
Cause: The line between
speaker terminals is shorted.
Supplementary information: As the excess current is detected after operation of the speaker relay, the shorted speaker
terminal and the connected speaker can be identified.
Turning on the power without correcting the abnormality will cause the protection function to work immediately and the
power supply will instantly be shut off.

power supply will instantly be shut off.
When
the protection function worked due to abnormal DC output
Cause: DC output from the
power amplifier is abnormal.
Supplementary information: The protection function worked due to a DC voltage appearing at the speaker terminal. A cause could be a defect in the amplifier.
Turning on the power without correcting the abnormality will cause the protection function to work in 3 seconds and the power supply will be shut off.

Turning on the power without correcting the abnormality will cause the protection function to work in 3 seconds and the power supply will be shut off.
When
the protection function worked due to abnormal voltage in the power supply
section
Cause: The voltage in the
power supply section is abnormal.
Supplementary information: The protection function worked due to a defect or overload in the power supply.
Turning on the power without correcting the abnormality will cause the protection function to work in 1 second and the power supply will be shut off.
Supplementary information: The protection function worked due to a defect or overload in the power supply.
Turning on the power without correcting the abnormality will cause the protection function to work in 1 second and the power supply will be shut off.
When
the protection function worked due to excessive heat sink temperature
Cause: The temperature on
the heat sink is excessive.
Supplementary information: The protection function worked due to the temperature limit being exceeded.
Causes could be poor ventilation or a defect related to the thermal sensor.
Turning on the power without correcting the abnormality will cause the protection function to work in 1 second and the power supply will be shut off.
History of protection function
When the protection function has worked, its history is stored in memory with a backup.
Even if no abnormality is noted while servicing the unit, an abnormality which has occurred previously can be defined as long as the backup data has been stored.
For details of the history of protection function, refer to main menu 21 PROTECTION HISTORY.
The history of the protection function is cleared when self-diagnostic function is cancelled by selecting PRESET RESERVED (Memory initialised) of main menu 24 or when the backup data is erased.
