Maintenance/Service

Cleaning

Disconnect the AC cord, then use a damp cloth to clean the module’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 unit is securely screwed into a rack or otherwise supported.

Refer All Servicing to Alesis

We believe that the S4 Plus is one of the most reliable modules 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 XT 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.
