Periodically perform listening tests and/or formal acoustical measurements for proper performance. The interval between such tests will depend on the frequency of system usage and the conditions of use.

A simple test is to play a CD through it using well-defined, articulate, wide-range program material. Listen to ensure all drivers are working properly and for any evidence of distortion or other extraneous sounds. Test at several volume levels: very low, normal, and high.

All drivers should be tested for functionality and proper performance. A sine wave sweep at approximately 10% of rated power will usually reveal driver and/or enclosure problems in the form of distortion, buzzes, or rattles.

Normally, no periodic maintenance, beyond the testing and inspections detailed in Sections 11.1 and 11.2, is required to maintain the acoustical performance.

1 1 . 3 . 2 R o u t i n e M a i n t e n a n c e

Periodically do routine maintenance on the loudspeaker. The interval between maintenance times and the scope of the maintenance will depend on the installation and the conditions of use. It is strongly recommended that maintenance intervals not exceed 1 year.

Maintenance shall include but not be limited to:

1.Repair or replace of any item determined by inspection to be sub-standard for their intended use.

2.Replace any load supporting parts whose load handling integrity is the least bit questionable.

3.Lubricate all parts subject to friction using WD-40, Scott oil FS365, or similar. These are water-based lubricants with machine oil, surfactant, an anti-rust treatment.
