The 3904 Digital Deskphone is the ultimate command center for busy executives, managers, and administrators – anyone who needs maximum flexibility in a multiline phone. The 3904 Digital Deskphone sets a new standard for user empowerment, productivity, and low total cost of ownership. The new display-based user interface helps increase your productivity by giving you access to more features with fewer keys. The 3904 Digital Deskphone’s five-line by 24-character display – the largest in its class – is bordered by programmable line/feature keys and interactive soft keys, providing access to the features you need – when you need them. The navigation cluster conveniently guides you through onscreen menus and prompts, providing an unparalleled level of customization and personalization. All of the display-based keys are self-labeling, which puts an end to paper labels and time-consuming set designation. When the phone is plugged in, the display immediately shows the lines and features assigned to each key for convenient access. As new features and services are introduced or programming changes occur, key labels are automatically updated, further simplifying desktop management. Whether you’re using the handset, handsfree speakerphone, or a headset, the Mute key always detects and mutes the correct path, helping you be sure your private comments stay private.
