Installing the Test Drum
General Information
Handle the test drums with care! Once you
remove a test drum from its vial, you have 90
days to use up all the test strips. Do not open the
test drum compartment until all of the strips have
been used. Whenever the test drum compartment is
opened and closed, or when the batteries are replaced,
the meter thinks a new test drum has been inserted
and resets the 90-day countdown. The 90-day use-by
period no longer has any significance (see page 100).
If a partly used test drum is removed from the
meter and reinserted, the message “CTRL” flashes
in the display, indicating that a control test should
be performed. Perform a control test (see
Running
a Control Test
, on page 44) to ensure that the strips
are still usable. The display indicating the 90-day use-
by period (flashing test drum symbol and date) is still
invalid, however. If you use an expired test drum, you
may obtain incorrect blood sugar results.
