WARNING
Small parts of the device can come loose and be swallowed.
►Keep the device out of reach of children under the age of 3.
4.1 Prerequisites
The instrument is factory-calibrated when delivered. If the calibration
date has exceeded 12 months, the instrument should be
professionally adjusted, e.g. by DrägerService.
Optional: If the calibration date has been exceeded, a warning
message is displayed after the startup screen. Confirm the warning
message with a short press on the button or wait some seconds to
continue.
After the last alcohol intake, wait approx. 15 minutes before a
measurement is carried out. Residual alcohol that is still in the mouth
may cause incorrect measuring values. This may also occur by
aromatic drinks (e.g. fruit juices), alcoholic mouth sprays, medicines
and drops, as well as by burping and vomiting. Rinsing the mouth with
water or non-alcoholic drinks does not replace the wait time!
