Note:
Leave
the
power
cable
plugged
in
for
at
least
2-5
minutes
until
the
projector
returns
to
room
temperature
before
placing
the
projector
inside
the
soft
case.
Placing
the
projector
into
the
case
too
soon
after
switching
off
the
power
could
cause
the
projector
to
overheat.
The
projector
turns
off.
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
any
wired
video
devices
(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.
Note:
Wireless
range
may
vary
depending
on
environmental
conditions.
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
determine
the
size
of
the
projected
image.
Attention:
Ensure
that
projector
air
flow
is
sufficient
and
not
blocked
or
using
recirculated
air.
Please
also
ensure
that
the
projector
is
not
in
a
confined
space.
