MAINTENANCE/SERVICE

CLEANING YOUR QS7.1 / QS8.1

Before doing cleaning of any kind, always disconnect the AC cord.

For simple dusting and removal of minor dirt, wipe the instrument down with a slightly-damp cloth.

For heavy dirt, use a non-abrasive household cleaner such as Formula 409 or Fantastik. Spray the cleanser onto a cloth, then use the cloth to clean the unit.

NEVER spray any cleaner directly onto the QS — this can destroy the lubricants used in the switches and controls!

PREVENTATIVE MAINTENANCE

•Periodically check the AC cord for signs of fraying or damage.

•Make sure the entire bottom surface of the keyboard is supported, so the rest of the unit is not subjected to unnecessary bending.

•Place a dust cover over the QS when it is not in use.

The QS7.1/QS8.1 synths are some of the most reliable keyboards that can be made using current technology, and should provide years of trouble-free use. If problems should occur, however, do NOT attempt to service the unit yourself. THIS WOULD BE DANGEROUS, thanks to high-level AC and DC electrical voltages present in the instrument’s chassis.

Service on this product should be performed only by qualified technicians. THERE ARE NO USER-SERVICEABLE PARTS INSIDE.
