Line Keys and Programmable Keys

This section describes the Multiple Line/Call Appearance Keys (L1, L2, and L3) and 
the customizable programmable keys located at the top left on the phone.

Multiple Line and Call Appearance Keys

The 53i has 3 hard line/call appearance keys each with a corresponding status light. 
These line/call appearance buttons and lights can represent physical lines, calls for 
your extension or calls from a group that your extension is part of. By pressing a line/
call appearance button, you connect to the line or a call it represents. The line/call 
appearance light indicates the status of that line or call. When the phone is taken off-
hook, the phone automatically selects a line for you.

When you have more than one call, you can use the left and right navigation buttons 
(

3

 and 

4

) to scroll left and right to the different call information. Icons 3 and 4 

will appear if there is call information either left, right or both sides of the current 
information you are viewing.
The display shows which line the call information is referring to (L1, L2, L3, etc.), 
the Caller ID information (name and number, if available), the call status 
(Connected, Ring, Hold, etc.) and the timer specific to that call.
