Maintenance/Service
Cleaning
Disconnect the AC cord, then use a damp cloth to clean the keyboardÕs 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 when it is not in use.
