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.
