User's Guide Special keys
Headset key (Code 564)
This key provides for easy connecting to/disconnecting from calls when operating in headset mode (see
"Headset operation," page E.5). Press the key to receive dial tone or to answer a ringing call. Press the
key again or press RELEASE to disconnect from the call.
Call-forward key (Code 565 or 565XXX)
If you frequently call-forward your phone (see "Call forwarding," page D.7), you can program a
programmable feature key as a call forwarding key to automatically turn forwarding on and off. If you
always forward to the same extension, you can program a key with both 5 6 5 and the extension number.
Background announce key (Code 569)
During call waiting, you can also make a brief, private background announcement (see "Background
announce feature," page D.8) to the station's earpiece (if the station user has enabled the background
announce feature). Hold down the key until you hear a beep, then begin talking; release the key
when finished.
Override ring (Code 580)
The override ring feature lets you place a call — station-to-station, outside line — or leave a voice
message when another call is ringing. For full details on use of this feature, see "Override ring,"
page E.5.
