Installing the dmcRAC

The dmcRAC is only required when using a dmc1 master for a retrofit
application. The dmcRAC is not required on the dmc3-4 retrofit master.

Tools required:

• #1 Phillips screwdriver

To install the dmcRAC you must first
remove two screws from the dmc1 master
on either side of the antenna connections.
Refer to Figure 1 for screw locations.

Then place the dmcRAC board over the AM
and FM antenna positions lining the
connectors up with the antenna inputs.
Make sure to push in the antenna tabs
while inserting the AM connections. Once
the connectors are aligned push the

antenna board into place.

After the antenna board is in position,
use the enclosed screws, spacer and
washer to connect the board. Position the
lock washer on the spacer and insert

between the antenna board and the open
screw hole on the dmc1. Make sure the
lock washer is between the board the
spacer. Use the enclosed screw to fasten
the spacer in place. Repeat with both

sides of the dmcRAC board. Refer to
Figure 2 for completed board installation.
