8.4.2Periodic Inspection

8.5MAINTENANCE

8.5.1Performance Testing

Listening tests and/or formal measurements should be done periodically. The interval between such tests will depend on the frequency of system usage and the conditions of use. All transducers should be tested for functionality and proper performance. A sine wave sweep at approximately 10% of rated power will usually reveal transducer and/or enclosure problems in the form of distortion, buzzes, or rattles.

8.5.2Cleaning

Clean the exterior surfaces of the enclosures as required, using a damp cloth to remove any dust or dirt. After cleaning, use a clean dry cloth to remove any excess moisture.

CAUTION: To avoid damaging the exterior finishes do not use cleaning solvents or abrasives.

8.5.3Cosmetic Field Repairs

While the enclosure paint finish and wood is of high quality and durability, mars, marks, and other blemishes will likely appear from normal use. For paint touchup, contact the EAW Service Department for original factory paint (Sherwin-Williams Polane® 700T, water reducible polyurethane-acrylic enamel) and instructions for its application. Otherwise, use the closest match to this paint from a local Sherwin-Williams dealer. For cosmetically damaged wood, use common woodworking methods and materials as appropriate for the damage.
