4 Abiding by the fol-lowing rules can help prevent damage to your amplifier, yourself and others. The amplifier is equipped with a three-pronged AC power cord. To reducethe risk of electrical shock, NEVER remove or otherwise attempt to defeatthe ground pin of the power cord. Connect the amplifier ONLYto a properly grounded AC outlet of the prop-er voltage for your amp. Avoid sudden temperature extremes, rain and moisture. Also, avoid sud-den and intense impact. (If the unit has been subjected to any of the pre-ceding abuses, have it looked at by an authorized service center.) NEVERset the amplifier on a support that will not bear its weight. Always keep the total speaker impedance at or above the rated load. Unplug the amplifier before cleaning it.

DO NOTuse the amplifier if it has sustained damage to the chassis, con-trols, or power cord. Refer the unit to an authorized service center forinspection. Prolonged exposure to high volume levels may cause permanent hearingloss or damage. Such damage is progressive and irreversible!
