responsibility for the test results.
When not used for a long time, keep the device after taking out the
batteries. In case of testing after long-term storage, there might
be high tolerance of test results for the first 3 tests.
Replace the batteries when the battery indicator icon reaches
empty for the accuracy reason.
In case the measured value is higher than 0.1%BAC and you try
again without interval, then warm up time might be delayed.
