• Manual day/night mode (Code 560) — Allows manual setting of the system’s mode — day or night.
• Headset key (Code 564) — Provides for easy connecting to/disconnecting from calls when the user
is operating in headset mode. The user presses the key to receive dial tone or to answer a ringing
call; he/she then presses the key again to disconnect from the call.
• Call forward key (Code 565 or 565XXX) — Toggles call forwarding on and off. If the user always
forwards to the same extension, you (or the user) can program a key with both 5 6 5 and the
extension number.
• Conference (Code 570) — Serves the same function as the CONF fixed-feature key.
• Mute/DND (Code 578) — Serves the same function as the MUTE/DND fixed-feature key.
• Override ring key (Code 580) — Allows a user to place an outside call (CO or extension) while
another call is ringing in on the same station.
Note: To delete a programmable feature key, press HOLD instead of programming a value.
Private line key
If a private line has been established in CO line programming (see “Private line,” page E.2), that
CO line key must appear on that station’s phone to allow outbound access to the line.
