Cleaning the Computer
To keep the computer in good working order, you may need to clean
the imager window, color camera window, and the touch screen. Clean
the windows and the touch screen as often as needed for the
environment in which you are using the computer. To clean the
computer, use a solution of ammonia and water.
To clean the image window, camera window, and touch screen:
1 Press the Power button and choose to suspend the computer.
2 Dip a clean cloth towel in the ammonia solution and wring out the
excess.
3 Wipe off the imager window, camera lens, and flash area. Do not
allow any abrasive material to touch these surfaces.
4 Wipe dry.
There are no user-serviceable parts inside the 70 Series computer.
Opening the computer will void the warranty and may cause
damage to the internal components.
