12-3 Device Maintenance
This section describes routine device maintenance, in particular cleaning
methods, inspection methods, and how to replace Units.
12-3-1 Cleaning
Perform the following cleaning regularly to ensure the network is kept in the
best condition possible.
• Wipe the network over with a soft, dry cloth when doing daily cleaning.
• If dirt remains even after wiping with a soft, dry cloth, wipe over with a
cloth that has been wet with a sufficiently diluted detergent (2%) and
wrung dry.
• Units will become stained if items such as rubber or vinyl products or
adhesive tape are left on the Unit for a long period. Remove such items
during regular cleaning.
Note
Never use benzine, thinners, or other volatile solvents, or chemical cloths. The
Unit coating may change if these products are used.
12-3-2 Inspections
Always perform periodic inspections to ensure the network is kept in the best
possible condition.
Periodic inspections should occur every 6 months to a year. Periodic inspec-
tions should occur more frequently, however, for Units that are used in envi-
ronments subject to high temperatures, high humidity, or a lot of dust.
Materials Required for
Inspections
The following materials are required to perform periodic inspections.
Materials Used Regularly
Phillips screwdrivers and flat-blade screwdrivers
Screwdrivers for communications connectors
Testers (or digital voltmeters)
Industrial alcohol and pure cotton cloth
Materials Sometimes
Required
Synchroscope
Pen oscilloscope
Thermometer and hygrometer
Inspection Items
Periodically inspect the following items to ensure that they do not deviate from
the criteria. If the items deviate from the criteria, adjust the environment so the
criteria are met or adjust the Unit itself.
