represent a talk path to a panel, interface, fixed group, or party line, or
can activate a programmable control function.

Listen Window

The listen window is located directly above the talk window. It contains
one listen label per selector. Labels refer to the listen paths that are
established when the selector is pushed up.

Answer-Back Window

The answer-back window is located above the “Answer Back” selector.
It displays a list of as many as five incoming calls. The first caller’s
label is closest to the “Answer Back” selector and is highlighted.
Subsequent calls are placed to the right of the first in the window. This
list is called the answer-back stack.

Message Window

The message window displays panel status and error messages.

Symbol Window

The symbol window displays two graphic symbols. The functions of the
two symbols are as follows:

• Ear symbol—indicates when someone is listening to (monitoring) the

panel.

• Window-indication symbol—displays a W (for window) and a Roman

numeral I or II to indicate which talk/listen window is active, as
toggled by the “Swap” button (See “Swap Button (9)” on page 14.).

Non-Displaying Characters

Certain Latin characters that may be present in a label will not be
displayed on the ICS-2003 display screen and will be replaced by
spaces. These characters are:

• ` (grave) is displayed as a space

• | (bar) is displayed as a space

• _ (underscore) is displayed as a space

• ~ (asciitilde) is displayed as a space

• { (braceleft) is displayed as a space

• } (braceright) is displayed as a space

• ¬ (logicalnot) is displayed as a space

Users should avoid the use of these characters in labels that may be
configured on ICS-2003 panels as the replacement of the characters
with spaces could cause operator errors.
