Complete and thorough inspections should be done on a routine, periodic basis. The interval between inspections and scope of the inspections will depend on the conditions of use. This interval must not exceed 1 year.

All mountings and enclosures should be visually examined for any condition that may affect mounting integrity. A complete inspection should include, but not be limited to, looking for these types of damage to DSA Series loudspeakers and parts:

bends breaks broken parts corrosion cracks

cracks in welded joints deformation

DANGER: Should any of the above listed types of damage exist, immediately remove the affected part from service for repair or replacement. If there is any question about the integrity or capability of any mounting or rigging part to perform its intended function, it must be immediately removed from service for repair or replacement.

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.

Careful listening will usually reveal transducer and/or enclosure problems in the form of distortion, buzzes, rattles, or non-function.

8 . 1 . 3 C L E A N I N G

The sides and rear of the enclosure function as a heat sink for the internal amplifiers. Because of this, they must remain relatively free of dust and dirt to ensure good heat transfer to the surrounding air. If these surfaces need cleaning, use a vacuum and/or damp cloth to remove any dust or dirt.

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