SERVICE:
The following information is provided in the unlikely event that your unit requires service.
1) Be sure that the unit is the cause of the problem. Check to make sure the unit has power, all
cables are connected correctly, and the cables themselves are in working condition. You may
want to consult with your dealer for assistance in troubleshooting or testing your particular
configuration.
2) If you believe that the ART unit is at fault, go to www.artproaudio.com.
Select “Support”, then “Return Authorization Request” to request a return authorization number.
3) If you are returning the unit for service, pack the unit in its original carton or a reasonable
substitute. The original packaging may not be suitable as a shipping carton, so consider putting
the packaged unit in another box for shipping. Print the RA number clearly on the outside of the
shipping box. Print your return shipping address on the outside of the box.
4) Include, with your unit, a note with the RA number and your contact information, including a
return shipping address (we cannot ship to a P.O. box) and a daytime phone number, and a
description of the problem, preferably attached to the top of the unit. Also include a copy of your
purchase receipt.
