Removing the HMS-15AC Grille Frame

If a cinema installation requires it, HMS-15AC grille frames can be easily removed. For safety reasons, grille frames for the HMS-15AC include an L-bracket securing them to the bottom of the cabinet; it must be removed before the grille can be detached.
Use a Phillips-head screwdriver to loosen the pan head screw on the bottom front of the cabinet securing the grilleframe’s L-bracket. Slide the L-bracket forward to remove it. Set the L-bracket aside.
Re-tighten the pan head screw without the L-bracket installed.
Unsnap the corner treeloks of the grille frame and remove the grille.
Caution
For installations that require grille frames, do not remove the L-brackets securing the HMS-15AC grille frames.
