Flush Mounting the Device
Be careful when cutting the hole to flush mount the device.
There is only a small amount of clearance between the case and
the mounting holes, and cutting the hole too large could
compromise the stability of the device after it is mounted.
The included template and hardware can be used to flush mount
the device in your dashboard. There are three options for
hardware based on the mounting surface material.
• You can drill pilot holes and use wood screws.
• You can drill holes and use nut plates and machine screws.
The nut plates can add stability to a thinner surface.
• You can punch and tap holes, and use machine screws.

Starting in one corner of the mounting location, place a nut
plate
on the back of the mounting surface, lining up the
large and small holes.
The raised portion of the nut plate should fit into the larger
hole.

Install the foam gasket
The pieces of the foam gasket have adhesive on the back.
Make sure you remove the protective liner before installing
them on the device.

If you will not have access to the back of the device after you
mount it, connect all necessary cables to the device before
placing it into the cutout.
To prevent corrosion of the metal contacts, cover unused
connectors with the attached weather caps.

Apply marine sealant between the mounting surface and the
device to properly seal and prevent leakage behind the
dashboard.
