Message Waiting Indicator (Mwi); Display - Nortel Meridian SL-100 Reference Manual

Message waiting indicator (MWI)

The MWI indicates that a message is waiting to be heard. This LED also
flashes when the set is ringing. If the set is ringing when someone is leaving a
message, the LED flashes until the set stops ringing.

Display

The display has two 31-character lines. The top display line shows information
like DN, the number of user presses when the set is in use, and time and date.
When the information exceeds 31-characters, a scroll icon appears and the rest
of the display may be seen by scrolling.
The second line displays the feature key labels for the three programmable
self-labeled keys. Each feature label consists of up to seven characters. The
first character is an icon displaying the status of the feature. When the set is in
Options mode, the top line displays related prompts and the bottom line
displays key labels. There are six icon indicators showing various options and
set status. Table shows examples of these icons and their descriptions.
