4-10 Chapter 4: Operation
Label Orientation
Because
the
RealScan
74
produces
an
omni
‐
directional
scan
pattern,
bar
code
labels
can
be
read
from
many
different
angles.
The
RealScan
74
reads
the
labels
on
the
leading
side
of
a
package,
the
trailing
side,
the
bottom
side,
the
top
side,
the
side
opposite
the
operator,
and
the
side
next
to
the
operator.
Products
can
be
read
from
right
to
left
or
from
left
to
right.
Active Scan Zone
The
active
scan
zone
is
the
area
where
the
unit
can
read
a
bar
code
label.
The
colored
lines
in
the
illustrations
indicate
this
area.
The
illustration
on
the
right
shows
the
scan
zone
for
the
leading,
trailing,
bottom,
and
the
back
(opposite
the
operator)
sides.
The
illustration
on
the
left
shows
the
top
‐
down
zone
where
the
unit
can
read
the
top
of
an
item
and
the
front
‐
up
zone
where
the
unit
can
read
the
front
of
an
item.

Multiple Reads
Only
one
good
read
is
reported
if
a
bar
code
label
is
placed
on
the
scanner
window
and
left
there.
The
scanner
firmware
inhibits
a
second
read
of
the
same
label
if
it
occurs
within
a
preset
time
of
a
good
read.
The
preset
time
is
programmable
from
350
ms
to
450
ms,
then
450
ms
to
1500
ms—in
increments
of
150
ms.
The
default
is
450ms.
To
read
the
label
a
second
time,
remove
the
label
from
the
scan
window
and
scan
the
label
again
when
the
time
‐
out
period
has
elapsed.
