Troubleshooting
„ Power
❏ When the power is turned on, "AMP Diag Mode" appears on the display of the main unit.
• The protection circuit function may have operated. If the unit suddenly enters the standby state and "AMP Diag Mode" appears on the display
of the main unit when the power is turned on again, this function is diagnosing whether or not the main unit is malfunctioning or there is an
abnormality with the speaker cable connection. When the diagnosis is complete, the following messages are displayed.
If the unit returns to the normal ON state after "CH SP WIRE" appears on the display, the speaker cable may have been short-
CH SP WIRE
circuited. After setting the power of this unit to standby state, connect the speaker cable again. The wires exposed from the tip of the
speaker cable do not stick out of the speaker terminal.
If the operation has stopped with "NG" displayed on the display, set the power of this unit to standby state immediately and remove the
NG:
power plug from the outlet. The unit may be malfunctioning. Consult a dealer.
❏ The unit turns off unexpectedly
• If "5. Hardware" - "Power Management" - "Auto Standby" on the Setup menu is activated, the unit automatically enters the standby mode.
• 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.
