Please treat it with respect and operate it properly.  \nUSE COMMON SENSE AND ALWAYS OBSERVE THESE PRECAUTIONS: WARNING: EU: permission from the Supply Authority is needed before connection.  \nWARNING: Vacuum tube amplifiers generate heat. To insure proper ventilation always make certain there is at least four inches (100mm) of space behind the rear of the amplifier cabinet.  \nKeep away from curtains or any flammable objects.  \nWARNING: Do not block any ventilation openings on the rear or top of the amplifier. Do not impede ventilation by placing objects on top of the amplifier which extend past the rear edge of its cabinet.  \nWARNING: Do not expose the amplifier to rain, moisture, dripping or splashing water. Do not place objects filled with liquids on or nearby the amplifier.  \nWARNING: Always make certain proper load is connected before operating the amplifier.  \nFailure to do so could pose a shock hazard and may result in damage to the amplifier.  \nDo not expose amplifier to direct sunlight or extremely high temperatures.  \nAlways insure that amplifier is properly grounded. Always unplug AC power cord before changing fuse or any tubes. When replacing fuse, use only same type and rating.  \nAvoid direct contact with heated tubes. Keep amplifier away from children.  \nBe sure to connect to an AC power supply that meets the power supply specifications listed on the rear of the unit. Remove the power plug from the AC mains socket if the unit is to be stored for an extended period of time. If there is any danger of lightning occurring nearby, remove the power plug from the wall socket in advance.  \nTo avoid damaging your speakers and other playback equipment, turn off the power of all related equipment before  \nmaking the connections.  \nDo not use excessive force in handling control buttons, switches and controls. Do not use solvents such as benzene or paint thinner to clean the unit. Wipe off the exterior with soft cloth.  \nBe sure to have the warranty card filled out by the store at which it was purchased and return to Mesa/Boogie.  \nYOUR AMPLIFIER IS LOUD! EXPOSURE TO HIGH SOUND VOLUMES MAY CAUSE PERMANENT HEARING DAMAGE !
