Cleaning

Disconnect the AC cord, then use a damp cloth to clean the AI-3's metal and plastic
surfaces. For heavy dirt, use a non-abrasive household cleaner such as Formula 409
or Fantastik. DO NOT SPRAY THE CLEANER DIRECTLY ONTO THE FRONT OF
THE UNIT AS IT MAY DESTROY THE LUBRICANTS USED IN THE SWITCHES
AND CONTROLS! Spray onto a cloth, then use cloth to clean the unit.

Refer All Servicing to Alesis

We believe that the AI-3 is one of the most reliable multieffects processors that can be
made using current technology, and should provide years of trouble-free use.
However, should problems occur, DO NOT attempt to service the unit yourself. High
voltage/high current DC voltages are present at several points within the chassis.
Service on this product should be performed only by qualified technicians. NO
USER-SERVICEABLE PARTS INSIDE.
