attained in certain
areas.
●Has the focus been set correctly?
see page49
●Has the projection angle been increased by adjusting the feet?
There are cases where the vertical focus is difficult to align if the
projection angle is too large.
●Is the projection distance suitable?
The recommended projection distance range is between 1.1m and
14.5m. Locate the projector within this distance range.
see page24
●Is the lens soiled?
see page25
●Is the projection light shining at right angles onto the screen?
see page84
●Is the lens fogged?
Condensation will form on the surface of the lens when the projector
is suddenly brought into a warm room from a cold room, and this
may lead to the image seeming blurred. In this event, switch the
power off and leave the unit to stand for a while.
●Has the [Sync., Tracking and Position] been adjusted?
The image can be adjusted by regulating the [Tracking] and [Sync]
buttons on the projector while monitoring the image on screen.
Adjustments can also be made by opening the [Menu].
