This section describes the routine cleaning and inspection recommended as
regular maintenance. Handling methods when replacing Digital Indicators are
also explained here.
Clean the Digital Indicators regularly as described below in order to keep the
Network in its optimal operating condition.
• Wipe the Digital Indicator with a dry, soft cloth for regular cleaning.
• When dust or dirt cannot be removed with a dry cloth, dampen the cloth
with a neutral cleanser (2%), wring out the cloth, and wipe the Digital Indi-
cator.
• Smudges may remain on the Digital Indicator from gum, vinyl, or tape that
was left on for a long time. Remove these smudges when cleaning.
Note Never use volatile solvents, such as paint thinner or benzene, or chemical
wipes to clean the Digital Indicator. These substances may damage the sur-
face of the Digital Indicator.
Inspect the system periodically to keep it in its optimal operating condition.
In general, inspect the system once every 6 to 12 months, but inspect more
frequently if the system is used in high-temperature, humid, or dusty condi-
tions.
Prepare the following equipment before inspecting the system.
A flat-blade and a Phillips screwdriver, a screwdriver for connecting communi-
cations connectors, a tester (or a digital voltmeter), industrial alcohol, and a
clean cloth are required for routine inspection.
A synchroscope, oscilloscope, thermometer, or hygrometer may be required.
Check the items in the following table and correct any condition that is below
standard by adjusting the Digital Indicator or improving the environmental
conditions.
