STEP 1 Enter the Code Mode.
Insert a test strip to turn on the meter.
Push it all the way in until it will go no
further. Avoid bending the test strip. The
display check will appear. Then the code
number is displayed for three seconds.
(The first time you use the meter, three
dashes Q will appear, meaning that
there is no code stored in the memory.) If
three dashes appear any other time, see
page 48 of "Display Messages and
Problem-Solving Guide."
STEP 2 Match the Code Numbers.
Compare the code number on the meter
display with the code number on the test
strip vial. If the two code numbers
match, you may begin testing. If they do
not match, follow Step 3.
