Keep these instructions.

Heed all warnings.

Follow all instructions.

Do not use this apparatus near water.

Clean only with dry cloth.

Do not block any ventilation openings.  Install in accordance with the manufacturer’s instructions.

Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that produce heat.

Do not defeat the safety purpose of the polarized or grounding-type plug.  A polarized plug has two blades with one wider than the other.  A grounding type 

plug has two blades and a third grounding prong.  The wide blade or the third prong are provided for your safety.  If the provided plug does not fit into your 

outlet, consult an electrician for replacement of the obsolete outlet.

Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.

Only use attachments/accessories specified by the manufacturer.

Unplug this apparatus during lightning storms or when unused for long periods of time.

Refer all servicing to qualified service personnel.  Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug 

is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, 

or has been dropped.

To insure proper ventilation always make sure there is at minimum four inches (101.6mm) of space behind the rear of the apparatus.  The ventilation should 

not be impeded by covering the ventilation openings with items, such as newspapers, tablecloths, curtains, etc.  Do not impede ventilation by placing objects 

on top of the apparatus which extend past the rear edge of its cabinet.

When Rack Mounting this unit proper ventilation space must be maintained. Do Not cover or block Front and Rear and allow at least 2” of open “breathing” 

space on both sides of the unit.  

No naked flame sources, such as lighted candles, should be placed on the apparatus.

The apparatus shall not be exposed to dripping or splashing and no objects filled with liquids, such as vases, shall be placed on the apparatus.

WARNING:  To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.

The AC plug is the mains disconnect.  The plug should remain accessible after installation.  The “OFF” position of the power switch does not disconnect all poles.

WARNING:  EU: permission from the Supply Authority is needed before connection.

WARNING:  Always make sure proper load is connected before operating the amplifier.  Failure to do so could pose a shock hazard and may result in damage 

to the amplifier.

Do not expose amplifier to direct sunlight or extremely high temperatures.

Always insure the amplifier is properly grounded.  Always unplug AC power cord before performing ANY service to the amplifier, including but not limited to 

changing the fuse.  Use only same type and rating when replacing fuse. 

Keep amplifier away from children.

To avoid damaging your speakers and other playback equipment, turn off the power of all related equipment before making the connections.

Do not use excessive force when handling buttons, switches and controls.  Do not use solvents such as benzene or paint thinner to clean the unit.    

Always connect to an AC power supply that meets the power supply specifications listed on the rear of the unit.  Export models: always insure unit is wired for 

proper voltage.  Make certain grounding conforms with local standards.

YOUR AMPLIFIER IS LOUD!  EXPOSURE TO HIGH SOUND VOLUMES MAY CAUSE PERMANENT HEARING DAMAGE!

Your MESA/Boogie® Amplifier is a professional instrument.  Please treat it with respect and operate it properly.
