Basic Overview
Button Layout
The button layout on the messenger keypad is arranged in a 3 x 3 grid which offers nine different
buttons. The keypad and messenger is designed so that buttons A,B,C,F,G,H, and I correspond to
the boxes along the outer edge of the screen when in the menus, this allows for the buttons to be
generic and have multiple uses in order to reduce key count and make it easier to use. There are
two buttons on the keypad that are dedicated and they are the up arrow /space button and the
down arrow/backspace button.
Figure 1
, below, shows the keypad layout of the messenger with
letter overlays (they are not actually on the messenger, just in the image) along with their
descriptions/references in Table 1. For instance later in the manual if one of the steps is to press
the upper right button it would be button G in
