Mounting the Projector
When mounting of the projector is required, do it using the embedded three screw holes (M6 nuts) at the bottom of the projector.
Precaution for ceiling-mount
• To ceiling-mount and adjust the projector, special exper-
tise and techniques are necessary. Be sure to ask your
dealer or specialist to perform the work.
• Do not mount on places that will be subjected to knocks
and vibrations.
• As the depth of the screw holes is 10mm, use screws
shorter than 10mm but longer than 6mm. Otherwise, the
screws will damage the internal parts of the projector
causing malfunction.
