Panning
The MX1-IS display can be panned around using keypress sequences so the user can view an
entire virtual 640 x 480 pixel screen. Initially, the 20 columns and 20 rows in the top left corner of
a virtual screen are displayed.
When the Pan Home key sequence is pressed, the cursor moves to the top left hand corner of the
virtual screen display.
When the initial 20 row x 20 column portion of the screen is displayed:
•
and the Pan Right key sequence is pressed, columns 10 through 30 are shown on the
display.
•
and the Pan Down key sequence is pressed, rows 5 through 25 are shown on the
display.
Panning activation and the pan Factor are configurable in BIOS Setup.
Display Window and Virtual Screen
When the host sends a virtual screen to the MX1-IS, the display window cannot show the whole
virtual screen. The display window can only show parts of the virtual screen.
The virtual screen is a 25 line x 80 column screen that the host sends to the MX1-IS.
The display window is the part of the virtual screen viewed on the MX1-IS. Usually the window is
either 10 lines x 20 columns or 20 lines x 20 columns.
The size of the display window is set by the default font parameter in the BIOS Setup. A default
font size of 8x8 initiates a 20 line x 20 column screen and a default font size of 8x16 initiates a 10
line x 20 column screen display.

Cleaning the Display/Scanner Aperture
Keep fingers and rough or sharp objects away from the scan aperture and display. If the display or
scan aperture becomes soiled or smudged, clean only with a standard household cleaner such as
Windex(R) without vinegar or use Isopropyl Alcohol. Do not use paper towels or harsh-chemical-
based cleaning fluids since they may result in damage to the surfaces. Use a clean, damp, lint-free
cloth. Do not scrub optical surfaces. If possible, clean only those areas which are soiled.
Lint/particulates can be removed with clean, filtered canned air.
Display Repair
There are no user-repairable or replaceable components in the LXE MX1-IS Display system.
