Section 6: Maintenance, Warranty & QSC Contact Information

Cleaning

The faceplate and chassis can be cleaned with a soft cloth and nonabrasive, mild cleaning solution. Products like Simple Green and Windex work well. Do not use powders or scrubbing pads of any type as they are usually abrasive and will permanently damage the finish of your DSP-3. Dampen a soft, lint-free cloth with the cleaning solution and wipe the DSP-3 down gently. Insure that cleaning solution does not get down into the connectors. Do not spray the solution directly onto the DSP-3 as it will penetrate into the connectors.

User Maintenance

There is no user-level maintenance on the DSP-3. Contact QSC’s Technical Services Department if service is required.

Warranty Information

If the DSP-3 isn’t working properly, please verify that a known good 9-pin serial cable is used between the DSP-3 and the computer. If proper operation can not be restored, the DSP-3 may require service. This must be performed by qualified service personnel. To obtain the location of you nearest QSC Authorized Service Center, please contact you QSC dealer or contact QSC’s Technical Services Depart- ment.
