•The programmable buttons are numbered from 01 left to right, bottom to top, ie. bottom left is button 01, top right is button 06.
•For systems running in key system mode, the first two programmable buttons, 01 and 02, are fixed as Intercom 1 and Intercom 2 buttons. Buttons 03 upwards are assigned as line buttons based on the Number of Lines setting or the number of analog trunks installed in the system.
•For systems running in PBX system mode, the first two buttons, 01 to 02, are fixed as call appearance buttons.
