Access menus for programming functions against display keys.  
This function can be programmed with or without data. If programmed with 
a setting of 1, the key accesses a different set of functions. See "Display 
Key Programming" on page 22. This function can be programmed through 
the phone by the user using an existing 

 Admin key.  

The 

 Admin key gives access to the menus for programming functions 

against 

 and 

 keys.

Add a display line for a call being handled (ringing, answered, on hold, etc) 
by the user. See "Call Appearance Keys" on page 4.  
This function does not require any data entered when programmed. 
However it is normal to enter some text such as a=, b= and so on for each 
call appearance key. This function can be programmed through the phone 
by the user using an 

 Admin key.

Sets a callback when free on busy extensions and callback when next used 
on unanswered extensions.  
This function does not require any data entered when programmed. This 
function can be programmed through the phone by the user  using an 

 

Admin key.  
When an extension called does not answer or is busy, pressing 

sets a callback on that extension. Whilst the callback is set, AutCB is 
shown with a   symbol. Pressing 

 AutCB again cancels the callback.  

When the extension becomes free or is next used, Ring Back to and the 
number appears on the phone that set the callback. Pressing 

 

answers the ringback and starts a call to the callback target.
