Function Keys
When a key has two labels, e.g., INFO/MUTE, the first label, e.g., INFO, refers to the
function of the key when not in a call; the second, e.g., MUTE, to the function when in a
call.
INFO/MUTE Key
This key has two uses:
1. When the handset is onhook and you are not in speakerphone mode, press this key
to briefly display your name and network address.
2. When you are in a call, press this key to mute your microphone; press it again to turn
off mute. While the microphone is muted, an
m
appears in the upper right-hand corner
of your LCD display.
LINE 1/2 Key
This key has four uses:
1. To upgrade your telephone (see the appendix, Updating the Software), press and
hold down the SET/CONF key as you unplug and then plug back in the AC power
adapter on the back of your telephone. (If using power-over-Ethernet, unplug the
network cable and then plug it back in.) Release the SET/CONF key after the MSG/
SPKR indicator illuminates and then immediately depress the LINE 1/2 key and release
it.
2. To accept a call-waiting call, press the LINE 1/2 key.
3. To switch between two calls, press the LINE 1/2 key.
4. When you are in a call and want to place a second call, press the LINE 1/2 key to get
a dial tone.
MENU/HANGUP Key
This key has three uses:
1. When the handset is offhook or the telephone is in speakerphone mode and you are
not in a call, the MENU/HANGUP key displays your phonebook, one entry at a time.
You can scroll up and down through your phonebook using the VOL keys and dial
the currently displayed entry using the DIAL/REDIAL key. To leave the phonebook,
press the MENU/HANGUP key again.
2. When the handset is onhook and the telephone is not in speakerphone mode, the
MENU/HANGUP key displays the configuration menu (see the section, Configuration
Menu). To leave the configuration menu, press the MENU/HANGUP key again.
3. When you are in a call and have another call on hold, the MENU/HANGUP key hangs
up the active call and takes the held call off hold, making it the active call. (Hanging
up the call without this key would terminate both calls.)
SET/CONF Key
This key has three uses:
1. Pressing this key in a data-entry field saves the currently displayed value and
terminates data entry for this field.
2. See the description for the LINE 1/2 key.
3. Pressing this key places the active call(s) into a conference.
