1.Unpacking

After removing the amplifier from the carton, inspect for any exterior damage to
the unit. If damage is noted, notify the carrier at once so that a claim can be
justified. Save all packing material. This is important when the claim is 

processed.

PRECAUTIONS

2.Ventilation

To offset heat generated by the unit, it is necessary to provide ample ventilation
around the unit. Avoid blocking or impeding the ventilation holes on the unit. To

prevent unnecessary problems, install the unit in a place free from any 

vibrations, direct sunlight, humidity or dust circulation.

3.Avoid spilling liquids or allowing materials to enter the  

   cabinet

If the unit gets wet or any foreign material enters the cabinet, immediately

disconnect the A.C. line cord and consult your dealer or qualified technician.
