NOTE ON SAFETY :
Symbol 
Fire or electrical shock hazard. Only original parts should be used to replaced any part marked with symbol 
. Any other component substitution (other than original type), may increase risk of fire or electrical shock hazard.
SHOCK, FIRE HAZARD SERVICE TEST :
CAUTION : After servicing this appliance and prior to returning to customer, measure the resistance between either primary AC cord connector pins ( with unit NOT connected to AC mains and its Power switch ON ), and the face or Front Panel of product and controls and chassis bottom.
Any resistance measurement less than 1 Megohms should cause unit to be repaired or corrected before AC power is applied, and verified before it is return to the user/customer.
In case of difficulties, do not hesitate to contact the Technical
Department at above mentioned address.

4. PROTECTION MODE
Explanation of microprocessor (QU01) [PROT-1 (pin6) and
PROT-2 (pin7)].
[A]The PROT-1 (pin6) is the port to detect the following abnormalities of the Power AMP
1.Detection of an abnormality in the DC offset voltage from the Speaker Output terminal.
If the voltage from the Speaker Output terminal exceeds approximately 1.2V (DC), Q955 or Q956 will turn on and the signal from the PROT-1 terminal will change to L from H.
2.Detection of an abnormal current from the power transistors (Q713 ~ Q716).
If an electric current of over 7A flows in Q713 or Q715, Q951, Q953 and Q957 turn on, and the signal from the PORT-1 terminal will change to L from H.
If an electric current of over 7A flows in Q714 or Q716, Q952, Q954 and Q957 turn on, and the signal from the PORT-1 terminal will change to L from H.
3.Detection of an abnormal temperature of the Heat Sink. If the temperature of the Heat Sink exceeds approximately +110 degrees C, the posistor (R969) will turn on Q958 and the signal from the PROT-1 terminal will change to L from H.
If any of the above three abnormalities is detected, the signal from the PROT-1 terminal will change to L from H, and the protection circuit will be activated, the signal from the SPK_OUT (pin10) changing to H from L and the speaker relays L751, L752 and L753 immediately turned off.
What this protection operation results in after this depends on how long the signal from the PROT-1 has to remain L.
s)F THE 02/4 PIN RECOVERS TO ( WITHIN AS SHORT A period of time as one second or less.
The MUTE indicator starts flickering, thereby indicates that the protection circuit has come into operation and automatically turns down the volume. The protection circuit is deactivated after approximately 15 seconds, so that readjusting the volume will allow normal use of the unit again. This protection operation is intended for the situation wherein the user has misused the unit temporarily and automatically resets the unit while the amp circuit is functioning properly.
s)F THE 02/4 PIN REMAINS , FOR MORE THAN ONE SECOND
The amp will be powered off by the P_ON (pin15) changing to H from L and Power relay L852 turned off Then, the STANDBY indicator flickers, thereby indicating that an error has occurred. This protection operation is intended for a failure in the amp circuit and immediately turns the power off to avoid the risk of any damage. Depending on how the user is handling the unit, this operation may be performed no matter if the amp is functioning properly.

|
|
|
This protection operation is intended for a breakdown of the AMP circuit or the power supply circuit and immediately shut s off the power in order to avoid the risk of damage.
To check if the amp circuit or the power supply circuit is broken, switch off the power and then switch it on again one minute later. This action will deactivate the protection operation.
If the RPOT-2 (pin7) remains L after the power is switched on again, the unit will be shut down again three seconds later with the STANDBY indicator flickering.
If the unit is powered on again and yet cannot get the protection operation deactivated, the amp circuit or the power supply circuit may be broken.
