14. Attach the wall plate cover
Secure the wall plate cover with a hexagonal wrench (M4) and three M4 × 12 mm hexagon socket head
cap bolts.
Depending on how the cables are wired, you may need to cut out parts of the wall
plate cover to allow the cables to be passed through it.
When cutting the thin section of the wall plate cover and passing the cables through,
make sure you smooth off any sharp edges to prevent damaging the cables.
Make sure you operate the cutter safely.
Caution
Only a specialist should remove or reinstall the projector for maintenance and repairs. Refer to
the projector User's Guide for instructions on maintenance and repairs.
Warning
❏
Never loosen the bolts and nuts after installation. Regularly confirm that the screws have
not become loose. If you find any loose screws, tighten them firmly. Otherwise, the
projector or wall mount may fall and cause personal injury or property damage.
❏
Do not hang on the wall mount or hang a heavy object on the wall mount. If the projector
or wall mount falls, it could cause personal injury or property damage.
