Display features
The M5216 has a tilt-able two-line display which shows you helpful information about incoming
calls or the features you activate. If your organization has installed the Calling Name/Reason
Display features, for example, your display shows the following information when you have
forwarded an incoming call to another telephone in your system:
Helen Jones 12345
Forward Jim Hunter 54321
The display can also show useful ACD status indicators. See Display Queue Status or Display
Threshold for examples.
Using the headset
The M5216 supports the use of Nortel's Liberation Headset (or an electret equivalent headset).
Your Customer Service Representative or System Administrator can provide you with
appropriate headsets and the instructions on pages 33-34 describe how to connect the headset to
the M5216.
Once plugged in, incoming calls are signaled by a short tone heard through the headset earpiece.
Plugging in the headset automatically places the telephone in an off-hook condition and the
"Mute Handset" button indicator flashes. To place the telephone on-hook, press the "Rls" button.
