Operation
Precautions
To
ensure
the
scanner
reaches
its
best
performance,
the
following
points
need
to
be
noticed
when
mounting
the
scanner:
a.
Do
not
place
the
scanner
under
direct
sunlight
or
any
other
bright
light
source
illuminating.
b.
When
placing
the
barcode
label,
one
must
be
careful
not
to
over
tilt,
skew
and/or
pitch
the
barcode.
c.
Do
not
place
the
device
at
specula
reflection
position.
The
LED
light
of
the
scanner
reflects
directly
back
on
the
scanner
if
it
is
placed
at
specula
reflection
position.
As
to
the
nature
of
CMOS
sensor,
it
will
not
be
able
to
read
any
barcodes.
d.
The
barcode
label
must
be
placed
within
the
effective
depth
of
field
(D.O.F.)
since
it
is
the
effective
reading
distance
for
the
barcode
from
the
scanner.
For
the
best
placing
position,
please
refer
to
the
Decode
Depth
of
Field
drawing.
