Liquid Crystal Display (LCD)
The MultiModemIIs backlit liquid crystal display (LCD) has two functions: to dis-
play the current status of the modem and to display configuration menus, which are
selected using the four pushbuttons on the front panel.

Option Selection

To select most configuration options, simply display the option in the LCD, and then
press the Enter button to select it. An OPTION SET message appears to confirm the
selection. To exit the OPTION SET message, press any button.
Some options, such as password options and phone number options, require you to
enter a character string. To select a character, press the áß and â buttons. To go to
the next character position, press the à button. To backspace, press the à button
before selecting a character. To exit without saving, press the à button several
times. To save a character string, press the Enter button.

Menu Structure

The LCD menus have a tree structure with multiple trunks, limbs, branches, and
twigs. For a schematic view, refer to the menu map on the next page.
Trunks are the major divisions of the menu tree. There are seven trunks: Status, Ba-
sic Options, Advanced Options, Remote Configuration, Diagnostics, Phone Number
Memory, and Caller ID. Use the áß and â buttons to move between trunks.
Limbs are subdivisions of trunks. Use the à button to move from a trunk onto its
first limb, and the áß and â buttons to move between limbs on the trunk.
Branches are subdivisions of limbs. Use the à button to move from a limb onto its
first branch, and the áß and â buttons to move between branches on the limb.
Twigs are status screens and options that are accessible only from branches. Use the
à button to move from a branch to its first status screen or option; then press the áß
and à buttons to move between options, and press the Enter button to select an op-
tion.
