4412D+ 3
The 4412D+ telephone contains 24 line buttons, but only 12 of these have 
LEDs associated with them. You can use the two-line display to choose 
features; the display’s functionality is much like that of an MLX-28D telephone. 
The 4412D+ telephone also has a speakerphone.
Besides the four softkeys that select items from the display, the 4412D+ 
telephone also has the following fixed buttons:
■ Volume
■ Hold
■ Conf (Conference)
■ Trnsfr (Transfer)
■ Redial
■ Spkr (Speaker)
