GALVANIC ISOLATOR & BONDING
SYSTEM MONITOR
1. The ground wire and galvanic isolator monitor is self-
testing. To ensure it is operating correctly, press the “test”
button and monitor its activity.
During the self-test process all four LED’s will light in
this order:
Ground wire normal
Ground wire fail
Galvanic isolator normal
Galvanic isolator fail
Then it will pause and light again galvanic isolator fail.
When the fail lights up on each component check you will
also hear an audible alarm. If the LED’s do not light in
this order or the alarm does not sound, the unit has failed
its self-test and should be replaced.
2. Periodically, check the wire connections to ensure they
are clean and tight.
STEREO/CD CHANGER/DVD PLAYER/
TELEVISION
Since most of the same cleaning and maintenance tips
overlap on these entertainment components, they will be
grouped together.
1. To clean the CD slots in stereos, DVD players use a dry
or slightly water moistened swab to remove any buildup
of debris. This monthly procedure will assist in preventing
the CD discs from being scratched.
2. To clean the faceplates of the various units use a dry soft
cloth. If the faceplate is stained badly, use a moist cloth
with a neutral cleaner. Do not use harsh, caustic or alcohol
based chemicals to keep the letters from coming off the
faceplate. Do not use silicone spray or WD-40 since they
could damage mechanical parts.
3. If these units will not play CD’s properly it they may
have developed condensation. Wait 1 hour and retry.
4. Keep all remote controls out of extreme heat and high
moisture environments. Change batteries often for best
operation.
5. Periodically check CD discs for scratched and dirty
ones. Clean the dirty ones with a cleaning kit which can
be purchased at most electronic stores.
6. With flat screen televisions, do not attempt to service
the unit yourself since high voltage exists.
7. To clean the flat screen display, dampen a soft cloth
with water or a mild detergent. The best cleaner is a screen
cleaning tissue specifically designed for antistatic coating.
Never use flammable cleaning materials or glass cleaners
with ammonia since they attack the television screen
surface.
