CAUTION:
Incorrect ADU option switch settings can cause service interruptions. Do
not change any option switches except the ones listed for equipping
digroups. For FPB Mode 1 systems, removing the ADU will interrupt
service on digroup A. Therefore, this procedure requires that a Mode 1
system has all digroups equipped.
NOTE:
If the ADU you are installing is a replacement, the system configuration
(S1 through S11) options must be set as directed in the previous Steps.
Remove ADU (Figure 1) from bank being equipped.

CAUTION:

loss of service or may introduce errors into the digital bitstream.

DIGROUP indicators lighted (BCU C, D DIGROUP indicators will also be
