SYMPTOM	PROBABLE CAUSE
1 No power	Check connections to the amplifier's Ground, B+ & Remote
	terminals. Check connection at "+" terminal of the battery.
	Check the remote turn-on terminal. Ensure it receives power
	when the source is turned on (or when the switch is turned
	on). Refer to the Installation Section. Check the power line
	fuse: if fuse is blown, replace it; if fuse continues to blow,
	check the power wire and also the amplifier for a short. If the
	short is in the power wire, fix it; if the short is in the amplifier
	itself, see your Coustic dealer.
	Check the voltage at the amplifier, and the remote ON/OFF

		components; if all else fails, try rewiring the entire system.
		High operating temperature can be caused by an incorrect
