By default, the programmable feature keys’ initial state is “not programmed” (except in the case of
station 100, on which the upper left key is a day/night key). Use this function to change the
programmable feature keys system-wide. Users can later change the programmable feature key
positions for their stations as part of station programming.
Important: Future, system-wide changes made later here by the Installer will overwrite any station user
programming.
When prompted, press the desired programmable feature key location, then enter the appropriate digits
on the dial pad and confirm by again pressing the same programmable feature key.
To determine how a programmable feature key is currently programmed, press the key, note how it is
programmed, and press the key again.
The keys can be programmed as follows:
CO line key
If the digits entered are 1–12, the key will serve as a CO line key.
Note: Removing the line key appearances will set the station(s) to operate as a PBX with line access by
dialing 9 (or 8 or 7).
Station key
If the digits entered constitute a three-digit extension number, the key will become a station key
providing the appropriate lamp information (See “System fixed numbering plan,” page C.2).
Speed-dial key
If one enters 9 (or 8 or 7) plus a phone number, the key will become a speed-dial key for
outside calls. Alternatively, the user may enter the system speed-dial bin (600–699).
