Mounting the AR400
1. Position the AR400 on the wall or shelf, ensuring 5 inches (12.7 cm) of clearance on all sides.
2. Using the pre-drilled holes at the corners of the AR400 as a guide, drill four holes in the wall or shelf
for mounting the AR400.
3. Secure the AR400 to the wall or shelf using four 1-inch long #10 screws.

Doing so can damage the AR400.
Do not turn on the antenna ports from a host to which antennas are not connected.
