PRECAUTIONS

• Read all documentation before using your equipment. Retain all documentation for further reference. 
• Do not use this apparatus near water.
• Clean only with a dry cloth.
• Do not block any ventilation openings. Install in accordance with the manufacturers instructions.
• Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus that produce heat.
• Mains voltage must be correct and the same as  that printed on the rear of the unit. Damage caused by connection to improper AC voltage is not covered by any

   warranty.  

• 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 is provided for your safety. If the provided plug does not fit into your outlet,
   consult an electrician for replacement of the obsolete outlet.

• Always operate the unit with the AC ground wire connected to the electrical system ground.
• Protect the power cord from being walked on or pinched, particularly at plugs, convenience receptacles, and the point where they exit from the apparatus.
• Unplug this apparatus during lightning storms or when unused for long periods of time.
• Linking an output to an oscillograph - when in “bridge” mode - is prohibited or it would cause damage to the amplifier and to the equipment.
• Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as powersupply 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.

• The output level of the amplifier shall not exceed the marked sensitivity.
• Do not link the output of any amplifier channel back into another channel ‘s input. Do not parallel or series connect an amplifier’s output with any other amplifier’s

   output. 

• In  system’s setup, amplifier’s output power must be from 50% up to100% greater than the loudspeaker’s rated power. 
• Make sure that the signal is correctly connected to the amplifier’s input channel and according to the proper input mode.
• Please turn off the power switch before pulling off the power cord, before managing signal cables or before selecting the input mode switch. 
• Please clean the dust filter every 15 days.
