Notes:
• Don't force the code key into the meter — it is made to go into the meter only one way.
• If you see "code" and "- - -" on the display, turn the meter off and reinsert a code key into the meter.
4. Turn the code key over so the code number
faces away from you. Push it into the code
key slot until it stops.

5. Leave the code key in the meter until you
open a new box of test strips. Remember to
change the code key each time you open a
new box of test strips.
