deeply
discharged.
In
some
cases,
the

bring
it
into
an
acceptable
level
and
then
transition
to
a
normal
charge
cycle.
Troubleshooting Scanner
Note:
Make
sure
that

Is the scanner having trouble reading your symbols?

check
that

symbols:
•
Are
not
smeared,

voids.

Are
not
coated
with
frost
or
water

which
the
scanner
connects.

but

still
have

press
a
key
to
enter
it
(the
Enter/Return
key
or
the
Tab

for
example).

a
suffix
enables
the

to
output
the

plus
the
key
you
need
(such
as
“CR”)
to
