The strips will
expire at the end of the
current month. Before
the end of the month,
insert a new code chip
from a new box of
strips and ensure
the code chip number
matches the code number on the
strip container. Make sure the time and
date in the meter are correct.
Your blood glucose may
be extremely low, or
the strip may be
damaged or not properly
inserted. If you see this
error message after you
applied blood to the
strip, see Chapter 2,
"Unusual Blood Glucose Results." If
you see this error message before you
applied blood to the strip, remove
the strip and reinsert it, or replace
it if damaged. Verify that the code
number printed on the strip container
matches the code number printed on the
code chip currently inserted in the meter.
If the message reappears, call Accu-Chek
Customer Care at 1-800-363-7949.
