|The Alphanumeric Display messages help the display telephone user process calls, identify callers and customize features.|
The 22- and 34-Button Display Telephones have a three-line, 24-character per line alphanumeric display. The first line displays the date and time (while idle) and feature status messages. The second line is used extensively by IntraMail. The third line displays the Soft Key definitions.
The 34-Button Super Display Telephone has a nine-line, 24-character per line alphanumeric display. The first line displays the date and time (while idle) and feature status messages, just like the 22- and 34-Button Display Telephones. The second line is used extensively by IntraMail. Lines 4-9 are the comprehensive Super Display Telephone soft key definitions.
While a keyset is idle, pressing Volume Up or Volume Down adjusts the contrast of the display. There are eight user-selectable contrast control values. The value a user sets is “remembered” by the system and automatically restored in the event of a power down or system reset.
The brightness and contrast control presets let the keyset user preset the default active brightness, idle brightness, and contrast for their keyset display. The brightness presets are not available to a 22-button keyset since it doesn’t offer a backlit display.
The 34-Button Display and 34-Button Super Display telephones also have an illuminated dial pad. Dial pad illumination makes the keys more prominent and is helpful in difficult lighting areas. The dial pad lights when the user is busy on the phone and goes dark after the phone returns to idle.
This no longer occurs.
