2.10 Keyboard Functionality
The keyboard is logically arranged into four areas based on the frequency of use. The alpha and fixed
function keys will be used less frequently than the navigation and numeric keys.
The alpha keys contain all 26 characters of the ISO basic Latin alphabet. They are arranged in the same
order as a standard QWERTY keyboard. The alpha keys are used for text data entries as well as hexadecimal
(A to F) numeric data entries. When not entering data these keys are ignored.
