Continue with testing as usual; the battery indicator will remain
on-screen.
After 20 tests have been performed, there will be insucient bat-
tery charge to continue testing, and the monitor will no longer
operate until the battery is replaced. The battery icon will only
appear when a strip is inserted and the icon will disappear when
