Section 7:
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-4. Dampen a soft, lint-free cloth with the
cleaning solution and wipe the DSP-4 down gently. Insure that
cleaning solution does not get down into the connectors. Do not
spray the solution directly onto the DSP-4 as it will penetrate into
the connectors.
User Maintenance
There is no user-level maintenance on the DSP-4. Contact QSC's
Technical Services Department if service is required.
Warranty Information
If the DSP-4 isn't working properly, please verify that a
known good 9-pin serial cable is used between the DSP-4
and the computer. If proper operation can not be restored,
the DSP-4 may require service. This must be performed by
qualified service personnel. To obtain the location of your
nearest QSC Authorized Service Center, please contact
your QSC dealer or contact QSC's Technical Services
Department.
