Swivel-Mount Location Considerations
For optimal performance, consider these guidelines when selecting the swivel-
mount location�

device�
• The location is sturdy enough to support the device and the mount�
• You can route the cables either from under the swivel mount, or from behind the
device�
• The location is the appropriate distance from a compass�
Preparing the Swivel-Mount Base Installation
Use pan-head screws or bolts when securing the swivel-mount base� Screws or
bolts with countersunk heads will damage the base�

After you have chosen the location to install the swivel mount
determine whether you will attach the mount to the surface using screws or
bolts, and choose the appropriate fastening hardware:
• To attach the base with screws, use self-tapping, pan-head wood screws,
either size #8 or a diameter of
the pilot hole�
• To attach the base with bolts, use pan-head bolts, either size #8 or a
diameter of
bit of the same diameter as the bolt�
