Installing t e LC3 Expansion Kit(s)
Installing the Kit is straightforward and can be done by anyone with basic technical knowledge and
a screwdriver.
Step 1
If the LC3 is installed, turn it off and remove all cables connected to the Expansion Kit. If the RJ45
cables plugged into the Instrument Boxes are not labeled, it is recommended that you label them
before removing them from the system in order to make the process of reconnecting them later
much easier.

Remove the seven black screws from the top panel, seven black screws from the back panel and four
screws from the RCA connectors on the back panel as shown in the diagram.
