Remove
the interface cover before installing the projector so that it is
easier to connect the cables after installation.
Push up and hold the interface cover latch while pressing the
button on the side as shown. Pull the interface cover straight off
the projector.
If you will route the connected cables through the top of the
projector, remove the top panel from the interface cover. If you
will route the connected cables through the bottom, remove the
bottom panel.
Align the interface cover with the guides on the projector
and slide it until it clicks into place.
