Cause

a Power plug is not connected properly to an ac outlet. lPower switch is off.

a Connection cords are disconnected.

a Connection cords are connected improperly.

a The position of the input selector switch does not match the input of the component being used.

a The	input selector switch- 1	button is
on.
T h e	FULL MUTE switch is on. (	indicator

flashes)

Measures

1

lPlug in firmly.

lPress power switch on.

a Connect firmly in the socket. a Check the connections.

lChange the switch to match the input.

a Press the P T A ~ E s w i t c toh turn off.

.Press the FULL MUTE switch to turn off.

a Press the RESET button, then adjust the volume.

*Depress one of the CONCERT, SPATIAL, or DOLBY switches.
