PROGRAMMING THE LINE USAGE

Lines that are not used (connected) to the 420 must be turned OFF. If lines are added later they can be turned ON.

For system feature operations like call transfer, paging and intercom, line one must be connected and common to all 420 extensions in the system.

SETTING THE PRIME LINE

The PRIME LINE is the line that the 420 attempts to use when going off-hook when the phone is not ringing. Line 1 is the default.

If the phone is ringing and you go off-hook, the 420 will answer the ringing line. If more than one line is ringing, the 420 will answer the line that was ringing first.

NOTE:

If a line is NOT connected to the 420 and the LINE USAGE is NOT turned OFF, the LINE IN USE INDICATOR will flash.
