SUPERSET 4025 Telephone
The SUPERSET 4025 telephone is a multi-line, digital telephone set that comes in two versions
(non-backlit and backlit). The backlit version offers backlighting in the LCD, thereby increasing
visiblity in dimly lit environments. The backlighting of the SUPERSET 4025 telephone is line
powered, so there is no requirement for an AC Power Adapter. Both versions have the following
features:
• Alpha-numeric LCD with contrast control
• Three softkeys for feature access
• Fourteen line keys, each with a built-in line status indicator
• Ten fixed-function keys: SuperKey, Cancel, Hold, Redial, Transfer/Conference, Mes-
sage, Microphone, Speaker, Up Arrow, and Down Arrow
• Automatic selection of prime line
• Key selection of non-prime line
• Handsfree operation, group listening, and off-hook voice announce
• Handset, speaker, and ringer volume controls
• Ringer pitch control
• Message Waiting lamp
• Headset port
• Adjustable tilt mechanism.
