d.

PRE-TESTING NOTE
Users should follow good hygiene practices and we recommend donors wash their
hands before and after using the instrument
For accurate testing results, food, beverages, medications, smoking, vaping, or
substances that contain alcohol should not be consumed for at least
15 minutes
prior
to testing.
Allow
15 minutes
for any potential interfering alcohol to be cleared from the donor
before testing again.
It is recommended not to clean the instrument with high-alcohol content materials;
residual alcohol can cause background interference which a sensitive breathalyse will
detect.
Breath alcohol concentration can continue to rise for up to
2 hours
after the cessation
of drinking and care should be taken if a result close to the designated breath alcohol
concentration is indicated.
When a high breath alcohol level has been reached, it can take
10 hours
or more for
the breath alcohol level to return to zero.
If the test result is above the operational maximum limit, a plus sign (+) after the result
will be displayed.
CAUTION
Never inject fluids into the sample port. This could render the instrument inaccurate for
subsequent tests or temporarily disable it and may void any instrument warranty
