Accessibility
Accessibility features help a user who has a physical disability, such as restricted
mobility or limited vision, to use the 4800 SurePOS terminals successfully. The
following is a high-level list of the accessibility features:
v All controls are located on the front of the machine, in easy reach.
v Industry-standard serial and USB ports allow alternative I/O devices.
v Manuals are available in .PDF format and can be downloaded from the Web.
See “Related publications” on page ix for the Web address.

changes color when in low-power mode.
