16.20 KCOU Replacement

1)Make sure the Power Supply (KPSU16) DC power switch is off.

2)Mate and connect KCOU P6 cable connector to P6 on Base Unit motherboard so that the red wire is aligned as shown in Figure 5-23.

3)Position KCOU as shown in Figure 5-23.

4)Mate and connect KCOU P7 to P7 on the Base Unit motherboard.

5)Secure plastic stand-off tab and install screws 1 and 2.

6)Set SW400 ~ 475 to appropriate position. In most cases set to the normal position (NOR); if CO lines are connected to a PBX or are in close proximity to the Central Office, set to the PAD position to provide a 3 db loss in signal level.
