1. Trim and tape this template to the mounting location. Avoid cable areas.

2. Drill four 1/8" (3 mm) mounting holes at the indicated locations.

3. Drill a 3/8" (10 mm) hole at the location indicated on this template, and then
use the jig saw to cut the panel along the inside of the indicated line.

4. Install the four mounting studs into the unit by screwing the shorter section
into the back of the unit.

5. Use a 0.05

mounting stud! The studs have a reusable thread-locking patch pre-applied
from the factory.

6. Place the unit into the cut out of the mounting surface.

7. Place washers over the mounting studs, and then thread on one hex nut per
mounting stud.

8. Tighten all four hex nuts until the unit is snug against the mounting surface.
