Cleaning the Computer
To help assure long, trouble-free operation, keep the computer free of dust and use care with
liquids around the computer.
Be careful not to spill liquids into the computer. If the computer does get wet, turn the
power off immediately and let the computer dry completely before you turn it on again.
Clean the computer using a slightly damp (with water) cloth. You can use glass cleaner
on the display. Spray a small amount of cleaner on a soft, clean cloth and wipe the
screen gently with the cloth.
CAUTION
Never spray cleaner directly onto the computer or let liquid run
into any part of it. Never use harsh or caustic chemical products
to clean the computer.
Moving the Computer
The T2150CD series computer is designed for rugged durability. However, a few simple
precautions taken when moving the computer will help assure trouble-free operation.
Make sure all disk activity has ended before moving the computer. Check the Disk icon
on the computer and the indicators on any external disk drives.
If a CD is in the CD ROM drive, remove it.
Make sure the CD ROM drawer is securely closed.
Disconnect the external 3 1/2” diskette drive and all other peripherals before moving the
computer.
Turn off the power to the computer.
Close the display. Do not pick up the computer by its display panel or back (where the
interface ports are located).
Disconnect the AC power cord if it is connected.
Use the carrying case when transporting the computer.
