This section describes the routine cleaning and inspection required and the
equipment handling procedure required for replacement.
Clean the devices in the network regularly as described below in order to
keep the network in its optimal operating condition.
• Wipe the WT30 Terminal daily with a dry, soft cloth.
• When a spot cannot be removed with a dry cloth, dampen the cloth with a
neutral cleanser (diluted to 2%), wring out the cloth, and wipe the WT30
Terminal.
• A smudge may remain on the WT30 Terminal from gum, vinyl, or tape that
was left on for a long time. Remove the smudge when cleaning.
These substances could damage the surface of the WT30 Terminal.
Be sure to 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 at high temperatures or humidity
or under dirty/dusty conditions.
Prepare the following equipment before inspecting the system.
• Standard and Phillips screwdrivers
• Multimeter (or digital volt meter)
• Alcohol and all-cotton cloth
• Synchroscope
• Thermometer, hygrometer
Check the items in the following table to make sure that the WT30 Terminal
meets the standard.
If the WT30 Terminal does not meet the required standards, improve the sur-
rounding environment so that the standards are met or adjust the WT30 Ter-
minal.
