If the KXV3 board is installed, remove the screws, washers and nuts securing it to the rear panel. That will
free a panel that surrounds the BNC connectors. Remove that panel as well. You can leave the KRX3 plugged
into the K3.
Figure 9. Removing the KXV3 Board.
If there is a coaxial cable running from AUX RF BNC connector on the rear panel to the KRX3 sub-receiver
enclosure, disconnect it from the sub-receiver. You do not need to disconnect this cable if it goes to the KAT3
antenna tuner module.
If present, remove the rear panel REF connector. Note that the hardware includes several washers and an O-
ring (see Figure 10). Keep all the hardware with the connector.
