Using the cable cover
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.
%Pass the power cord through cut-
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.
&Push hook 2 until it locks into
place.
