Fixed keys (same for all three models)
Hold: By pressing the hold key, you can put an active call on hold. Return
to the caller by pressing the extension key beside the flashing LCD
indicator.
Release (Rls): You can terminate an active call by pressing the Rls key
or by hanging up the handset. The release key is especially useful for
disconnecting handsfree and headset calls.
Volume control: The volume key controls the volume of the handset, the
speaker and the ringer. Raise the volume by pressing the right side of the
bar. Lower it by pressing the left side.
Mute: When engaged in a call, you can press the mute key. The party(ies)
to whom you are speaking cannot hear you. This is especially useful
when on a conference call and you are only listening. When you wish to
return to the two-way conversation, you must push the mute key again.
The mute key applies to handsfree, handset and headset microphones.
Speaker/Handsfree: The speaker key allows you to activate handsfree
and group listening features. Handsfree is only available on the M3310
and M3820 models and is enabled by the system administrator. If
handsfree is not configured at the switch, the telephone can only be used
to listen.
The table below indicates the mode the terminal is in when the speaker key is
operated under the various switch and set operations.
