PT-F300NT

unit : mm (inch)

L: Distance to screen

H: Height from the edge of screen to

center of lens

NOTE:

Illustrations show the projector installed

using optional ceiling bracket.

This illustration is not drawn to scale.

* This distance is especially recom-

mended for ceiling-mounted use and

other permanent installations.

NOTE:

Values shown are approximate. The value

for L (distance to screen) varies slightly

depending on the zoom lens characteris-

tics.

When the shortest projection distance is

used, a small amount of distortion may

occur in the image due to the zoom lens

characteristics.

The value for H (the height from the edge

of the screen to the centre of the lens) is

the value when the horizontal optical axis

shift function is not used. The value

decreases when the horizontal optical

axis shift function is used. For details,

see Shift range on page 7.
