Features 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, 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. -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 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 dirt and film. -Do not 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! Consider using quality hearing protection devices. - Do not transport other or additional equipment with the PortaBass telescoping handle. The handle is designed for use with the PBC2112 and PBC2210 only.
