Keep the Tuner Ribbon Cable oriented so that the red stripe is always on top, as indicated in FIG. 10.

Verify that all of the 20-pin connectors of the Tuner Ribbon Cable are securely plugged into their respective boards.

5.The Controller should only be powered back on once all Tuners are installed.

Removing Tuner Modules

In some cases it is necessary to remove the existing Tuner Module, in order to install a different Tuner Module. Since each Tuner Module uses 1 source input on the Audio Controller, you may choose to use the source input for other purposes.

1.Remove the cover from the Audio Controller.

2.Carefully remove the ribbon cable from the Tuner Module.

3.Remove the screws from the Tuner Module cover plate (on the Controller’s rear panel) and carefully slide the Tuner Module out of the chassis.
