Meridian SL-100 M3900 Meridian Digital Telephones Reference Guide
Message waiting indicator (MWI)
The MWI signals that a message is waiting to be heard. This LED
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 24-character lines. The top line shows information
like DN, the number of user presses when the set is in use, and time
and date. When the information exceeds 24-characters, a scroll icon
appears and you can see the rest of the display 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 6
describes these icons.
