Panasonic PT-L780NTE Operating Guide

When installing the projector to the ceiling, the accessory cable cover can be
used to cover the terminals or cords after removing the cut-away parts.

'Tighten the screw by turning it

clockwise. 

$Work the cut-away parts back and

forth several times to break the
fixing tabs. Smooth off any jagged
edges if necessary.

#Use pliers or similar to break the

perforated sections of the cut-
away parts.

away part S, and pass the other
cables through cut-away part L,
and then insert the tabs of the
cable cover into the mounting
holes in the projector.
