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 Wedge in a sturdy carton, with shock-absorbing
materials such as styrofoam pellets (the kind without CFCs) 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 the warranty. Next-
day service may be available for a surcharge.

Field repairs are not authorized during the warranty period, and repair attempts by
unqualified personnel may invalidate the warranty.
