10. Cautions when attaching the main board and upper case
When attaching the main board and upper case, there is danger of damaging the connector connecting
cables.
1) Secure the main board by tightening screws on the circuit board surface. Then tighten the screws on the
rear side of the projector by following the next step.
2) Tighten the screws from the rear panel of the projector in order of 1, 2, 3 and 4 shown in the diagram. If
tightening these screws in wrong order, the I/O metal located inside of the terminal panel might strain.

assembling the projector.
CAUTION:
In some cases that you remove thre upper
case with the loosen screw left in this hole,
the screw might be latched inside. Be sure to
confirm that this screw has been tightened
firmly before completing the maintenance.
