Maintenance/Service
Cleaning
Disconnect the AC cord, then use a damp cloth to clean the keyboard’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 the cloth to clean the unit.
Maintenance
Here are some tips for preventive maintenance.
• Periodically check the AC cord for signs of fraying or damage.
• Make sure the entire bottom part of the keyboard is supported
so that the case is not subjected to unnecessary bending.
• Place a dust cover over the QuadraSynth Plus when it is not in
use.
Refer All Servicing to Alesis
We believe that the QuadraSynth Plus is one of the most reliable
keyboards 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. The full AC line voltage, as
well as 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. THERE ARE NO USER-SERVICEABLE
PARTS INSIDE.
