Cotton buds, wipes and cloths lightly moistened with disinfectant are all
suitable for disinfecting the meter.
Allow areas you have wiped time to dry thoroughly.
Remove any fluff or lint that may remain.
Fold the drum compartment cover down and press until it closes. It
locks with an audible CLICK.
Ensure that the drum compartment cover is properly closed.
Notes
The test strip guide and measuring window must always be kept
clean. When you turn the meter on to perform a test, the test strip
is advanced over the measuring window and out through the test
strip guide. Any residues of blood remaining on the measuring
window or in the test strip guide may get onto the test strip and
contaminate it.
Make sure that no liquid enters the meter. Avoid scratching the
measuring window, as scratches could impair its measuring
function.
Do not spray anything onto the meter and do not immerse it in
liquid. Doing so may damage the meter's internal components
and stop it from working properly.
