Appendix A: Troubleshooting
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 QS when it is not in use.
REFER ALL SERVICING TO ALESIS
We believe that the QS 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.
OBTAINING REPAIR SERVICE
Before contacting Alesis, check over all your connections, and make sure you’ve read
the manual.
Customers in the USA:
If the problem persists, call Alesis USA at 1-310-841-2272 and request the Product
Support department. Talk the problem over with one of our technicians; if necessary,
you will be given a repair order (RO) number and instructions on how to return the
unit. All units must be shipped prepaid and COD shipments will not be accepted.
For prompt service, indicate the RO number on the shipping label. If you do not have
the original packing, ship the QS in a sturdy carton, with shock-absorbing materials
such as styrofoam pellets (the kind without CFCs, please) or “bubble-pack”
surrounding the unit. Shipping damage caused by inadequate packing is not covered
by the Alesis warranty.
Tape a note to the top of the unit describing the problem, include your name and a
phone number where Alesis can contact you if necessary, as well as instructions on
where you want the product returned. Alesis will pay for standard one-way shipping
back to you on any repair covered under the terms of this warranty. Next day service
is available for a surcharge.
Field repairs are not normally authorized during the warranty period, and repair
attempts by unqualified personnel may invalidate the warranty.
