IMPORTANT SAFEGUARDS AND PRECAUTIONS:

All Ampeg products are designed for continuous safe operation, as long as common sense is used and steps are taken to help avoid certain problems. Abiding by the following rules can help prevent damage to your amplifier, yourself and others.

• The amplifier is equipped with a three-pronged
	AC power cord. To reduce the risk of electrical
	shock, NEVER remove or otherwise attempt to
	defeat the ground pin of the power cord.
•	Connect the amplifier ONLY to a properly ground-
	ed AC outlet of the proper voltage for your amp.
• Avoid sudden temperature extremes, rain and
	moisture. Also, avoid sudden and intense impact.
	(If the unit has been subjected to any of the pre-
	ceeding abuses, have it looked at by an autho-
	rized service center.)
•	NEVER set the amplifier on a support that might
	give out under its weight.
• Always keep the total speaker impedance at or
	above the rated load.
• Unplug the amplifier before cleaning it. NEVER
	spray liquid cleaners onto the amplifier. Wipe it
	with a slightly dampened, lint-free cloth to remove
