placing
the
projector
inside
the

too
soon
after

be
sure

the

normally
and
disconnect
the

main
power
source.
Positioning
the
projector
To
determine
where
to
position
the
projector,
consider
the
size
and
shape
of
your
screen,
the
location
of
your
power
outlets,
and
the
distance
between
the
projector
and
the
rest
of
your
equipment.
Following
are
some
general
guidelines:
v
Position
the
projector
on
a
flat
surface
at
a
right
angle
to
the
screen.
The
projector
must
be
at
least
1.5
m
(4.9
ft)
from
the
projection
screen.
v
Position
the
projector
within
2.7
m
(9
ft.)
of
your
power
source
and
within
1.8
m
(6
ft.)
of
your
video
device
(unless
you
purchase
extension
cables).
To
ensure
adequate
cable
access,
do
not
place
the
projector
within
.15
m
(6
in.)
of
a
wall
or
other
object.
v
Position
the
projector
the
desired
distance
from
the
screen.
The
distance
from
the
lens
of
the
projector
to
the
screen,
the
zoom
setting,
and
the
video
format
determines
the
size
of
the
projected
image.
