If you are already on a call appearing on an MCO key and you press another MCO key, a line on the other MCO key is selected and the first call is dropped.

If a CO key is assigned, the CO Key LED will light when that specific trunk is used instead of the MCO key LED.

There are five gr oups of outside lines: 9 and 81-84 (default).

MCO keys cannot be assigned on the DSS/72 or the EM/24.

An MCO key must be assigned in programming mode. The MCO key cannot be assigned by the end user with FF key assignments.
