Figure 4-1. About Screen
The front panel interface uses the left-most keys (A, B, C, and D)
along with the display to provide dynamic smart key functionality.
These keys, along with the DEL and ENTER keys allow the user to
display and edit switch routing, configure the system interfaces
and modes, run self-test, perform diagnostic functions, and obtain
help information. Figure 4-2 shows the general hierarchy of the
command structure. Some variations may exist depending on the
version of the system firmware.
Smartkey D (bottom left) will always return the display to the
previous menu. The ENTER key is used to complete a manual
command or setting. The number keys are used for routes and
addresses. If a mistake is made, the DEL key can be used to
backspace. In any menu where numbers or letters are not being
entered, the DEL key can be used to return to the starting menu.
