CHAPTER 8 – PROJECT K2 S5800 CARE AND MAINTENANCE

The Project K2 S5800 loudspeaker system is sprayed in a poly- urethane finish and requires no maintenance other than an occa- sional dusting with a soft, dry, lint- free cotton cloth.

The horns may also be wiped with a soft cloth. Treat the surface very carefully to avoid scratching the finish. To remove fingerprints and smudges, apply a small amount of ammonia-free window cleaner to the cloth and gently clean the surface.

Never use any abrasive cleaners or chemicals to clean the enclo- sure. If the enclosure becomes perceptibly scratched or other- wise damaged, consult a qualified furniture repair shop.

The grilles should never be washed in water, which might cause discoloration or sagging. The grilles may be cleaned using a vacuum cleaner with the suc- tion set extremely low.

Should you wish to clean the woofer surfaces, use a soft, dry paint brush to carefully sweep the dust away. Never use a damp cloth.

JBL’s unique Charge-Coupled Linear Definition system is used for the crossover network, in which a direct (DC) bias current is constantly applied to the capaci- tors in the network circuit to acti- vate the elements, eliminating crossover distortion at zero elec- tric potential.

The battery has a life of about two years. Even if the battery voltage drops, the network will continue to function. However, in order to maintain superior sound quality, we recommend that you test and change the battery once a year. Note that the battery may leak and damage the holder and other parts if it is left in the speaker for a long period after exceeding the suggested duration.

To access the battery, unscrew the battery cover at the top of the terminal board and remove it. Always use a 9V, rectangular 006P-type battery and install it with the proper polarity.

The battery included in the shipped system is for testing purposes only. We recommend that you replace it as soon as possible.

All wiring connections should be inspected and cleaned or remade periodically. The frequency of maintenance depends on the met- als involved in the connections, atmospheric conditions, and other factors. Consult the Project K2 specialist dealer for specific recommendations.
