Securing the projector to the upper assembly
Step 6
Make sure the three knurl knobs
are loosened to fully expose to the
“tri-lock” mounting plate in the base
of the upper assembly. Carefully lift
the projector and insert the
mounting bracket mating special
tri-lock cutout into the mating
portion of the upper assembly.
Once inserted rotate the projector
and mounting bracket 180° and
secure the rear safety knob first to
prevent further rotation of the
bracket in the upper assembly.
Tighten the remaining two tension
knurl knobs until the mount
becomes rigid. The safety knob
should line up with the alignment
slot on the mounting bracket.
