The display-based user interface helps increase productivity by providing access to more features with fewer keys. The displays are bordered by programmable line/feature keys and interactive soft keys, providing quick access to features, options, and applications. The navigation cluster guides you through on-screen menus and prompts, giving an unparalleled level of customization and personalization.
All display-based M3900 phones feature self-labeling keys, which puts an end to paper labels and time-consuming set designation. 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. Self-labeling keys also enable users to personalize their feature key labels, helping to enhance productivity even further.
The M3900 series empowers you by providing unparalleled customization options for increased productivity and ease of use. You can customize the feature names displayed on the phone, choose from multiple ringing tones to help distinguish incoming calls, select from multiple languages, identify preferred name matching for incoming calls, and choose the format for the time and date.
With the “Smart” Mute feature, the M3900 series phone automatically senses whether you’re using the handset, headset, or handsfree, and mutes the correct path-helping you be sure your private comments stay private. With “Smart” Mute, you can also listen in on a conference call while you work on other tasks, without distracting the conference with extraneous background sounds.
