AT-OMNI-521
The AT-OMNI-521 decoder includes two
mounting brackets and four mounting screws,
which can be used to attach the unit to any at
surface.
1. Using a small Phillips screwdriver, remove
the two screws from the left side of the
enclosure.
2. Position one of the mounting brackets, as
shown below, aligning the holes on the
side of the enclosure with one set of holes
on the mounting bracket.
3. Use the enclosure screws to secure the
mounting bracket to the enclosure.
4. To provide added stability to the mounting
bracket, use two of the included screws
and attach them to the two holes, directly
below the enclosure screws, as shown
above.
5. Repeat steps 1 through 4 to attach the
second mounting bracket to the opposite
side of the unit.
6. Mount the unit using the oval-shaped
holes, on each mounting bracket. If using
a drywall surface, a #6 drywall screw is
recommended.
