Lifescan One Touch ll - Manual (Page 15)

You must use the
control solution:
❏ At least once a week.
❏ When you begin using a
new package of test strips.
❏ Whenever you suspect
the meter or test strips are
not working properly (for
example — when your
results are not consistent
with how you feel).
2. Checking the Meter with
the Check Strip
A purple and white check
strip is included with your
ONE TOUCH
® II Meter. The
check strip is used to make
sure your meter is work-
ing properly. Before doing a check strip
test, make sure the test strip
holder and the test area are
clean, dry, and lint-free. For
information, see page 42.
Make sure both sides of the
check strip are clean and dry.
