Abiding by the following rules can help prevent damage to your amplifier, yourself and others. -The amplifier is equipped with a three-prong AC power cord. To reduce the risk of electrical shock, NEVERremove or otherwise attempt to defeat the ground pin of the power cord. -Connect the amplifier ONLYto a properly grounded AC outlet of the proper voltage for your amp. If no grounded outlet is available, use only an approved method of adapting to a two-prong AC source. -Avoid sudden temperature extremes, rain and moisture. Also, avoid sudden and intense impact. (If the unit has been subjected to any of the preceding abuses, have it looked at by an authorized service center.) -NEVERset the amplifier on a support that might give out under its weight. -Always keep the total impedance at or above the rated load. -Unplug the amplifier before cleaning it. NEVER spray liquid cleaners onto the unit. Wipe the unit with a slightly dampened, lint-free cloth to remove dirt and film. -Dont use the amplifier if it has sustained damage to the chassis, controls, or power cord. Refer the unit to an authorized service center for inspection. -Amplifiers capable of producing high volume levels are also capable of inflicting permanent hearing loss or damage, if the exposure to such levels is prolonged. Such damage is progressive and irreversible! Caution is advised and ear protection recommended when playing at extremely loud levels. The chart below shows the U.S. Government Occupational Safety and Health Administration (OSHA) regulations which were in effect at the time of this publication for permissible noise exposure, per 29CRF1910, Table G-16. According to OSHA, any exposure in excess of those listed above could result in some hearing loss.
