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.
REFER ALL SERVICING TO ALESIS
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.
