The unit turns off unexpectedly
• The unit automatically switches to standby when the "System Setup" - "Hardware" - "Power Management" - "Auto Standby" setting in the Home
screen functions.
• The protection circuit function may have operated. In such a case, if the power is turned on again, "AMP Diag Mode" is displayed on the main
unit’s display, and the unit enters the diagnosis mode to check the unit for abnormality. As the result, if no problem is found, "AMP Diag Mode"
on the display disappears. Then, you can use the unit normally. If "CHECK SP WIRE" appears on the display, the speaker cables may be short-
circuited. Check if the core wire of a speaker cable is not in contact with the core wire of another speaker cable or the rear panel, and turn the
power on again If "NG" is displayed, remove the power plug from the outlet immediately, and consult the dealer.
•
The protection circuit function may have operated due to an abnormal rise in temperature of the unit. In such a case, the power turns off
repeatedly even if the power is turned on each time. Secure sufficient ventilation space around the unit, wait for a while until the temperature of
the unit decreases. Then, turn the power on again.
WARNING
: If smoke, smell or abnormal noise is produced by the unit, unplug the power cord from the outlet immediately, and contact the dealer or
our company's Support.
