First, you need programming sheets for this system. Find the feature you want to activate and the extension you want to activate it on.

The system is programmed by flipping a switch on the CPU. There are LEDS on the CPU that lightup and a two-didget display that tells you where you are at in programming. When programming no calls go in or out of system. After programming, return switch for normal operation, and then press the reset button on the CPU to lock in all programming.

Good Luck!!


If all else fails, use a BFH.
