28-Key Keypad
The 28-key keypad contains a Power button, application keys, scroll keys and function keys. The keypad is color-coded to indicate
the alternate function key (blue) values and the alternate ALPHA key (orange) values. Note that keypad functions can be changed by
an application so the mobile computer keypad may not function as described. See Table 2-2 on page 2-4 for key and button
descriptions and Table 2-1 on page 2-3 for the keypad special functions.
