Maintaining System Devices

This chapter describes cleaning the system and replacing system devices in the TD-x20,
TD-x25, TDZ-x20, and TDZ-x25 workstations.

Cleaning the System

Follow these guidelines for cleaning the system.
CAUTION Power off the system before cleaning the exterior surfaces, mouse, and keyboard. Do not
clean the CD-ROM drive.
Exterior Surfaces
Use a mild cleaning detergent and a clean cloth to clean the monitor screen and the exterior
surfaces of the base unit.
Mouse
On the bottom of the mouse, a retaining ring holds the tracking ball in place. To clean the
mouse, remove the retaining ring and turn the mouse over; the tracking ball will fall out.
Blow gently into the opening. Clean the tracking ball and rollers with a cotton swab and
alcohol. Replace the tracking ball and the retaining ring.
Keyboard
Dust the keyboard with a dry cloth. Aerosol cleaners are commercially available to remove
the dust between the keys of the keyboard. Never allow moisture on the keyboard or the
surface beneath the keys.
