Installation
■ Projection image position
Follow the instructions below to adjust the position of the projected image on the screen.
<Adjusting using the zoom>
This figure shows the limits within which the zoom function can alter
projection distance in relation to the screen size. Within these limits, it is
possible to adjust the image so that it fills the screen completely. (See
page 12.)
<Adjusting using the V. POS (vertical positioning)>
It is possible to adjust the vertical position of the projected image on the
screen up or down by half the height of the screen.
For example, shifting V. POS fully up will bring the lower limit of the
image above the centerline of the lens. (See page 12.)
<Adjusting using the adjusters>
When this unit is mounted on a tabletop, the position of the image can be
adjusted by using the adjusters located on the underside of the unit.
Adjust the height by rotating the movable part of the two screw-type
adjusters at the front bottom of the case. The adjustment range of these
adjusters is 3 cm (1-1/4 inch). Adjust with care as loosening them further
may cause them to separate from the main unit.
■ Keystone
When the unit is mounted at an angle to the screen, the image will be projected in a trapezoid manner. Use the keystone function in the
keystone section of 4 <SETUP> in the menu to rectify this. (See page 21.)
