Line Cards and the CPM2 supervisory signal on the LCD

display, and activates the buzzer to alert the operator.

The display will also indicate if additional signals are

waiting to be displayed and acknowledged.

3 The operator must press the [ACK] button to acknowledge

the signal manually. The CPM2 will scroll to the next

message if there are more messages to display.

4 The CPM2 returns to the Stand-by Mode when all signals

have been manually acknowledged.

When Option [12] is programmed as “00”, functions

described above will be bypassed. The default setting for
