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!

a breath test.
For hygiene reasons, hold the mouthpiece only on the grip zones.
Do not allow any high alcohol concentrations on the sensor, e.g.
by rinsing the mouth with a high proof alcohol shortly before the
measurement, as this will shorten the service life of the sensor.
Procedure
1. Remove the safety cap from the top of the device.
2. Insert a new mouthpiece (order no. 83 25 250) in the mouthpiece
receptacle (see section 3.1 on page 4).
For hygiene reasons, hold the mouthpiece only on the grip zones.

6 Maintenance
Calibration
Dräger recommends a device calibration every 12 months, because of
the sensor drift the uncertainty of measurement increases over
months. Instrument calibration and maintenance should only be
carried out by authorized persons, e.g. DrägerService.

be shown as information in the display after switching on the device.
Please confirm this information with the button. It shall remind you that
the device needs to be serviced in the next days. After the service
date, the device starts to count up how many days it is over the
requested service. This information can be confirmed by pressing the
button as well.
Cleaning
Do not immerse in fluids and avoid contact of fluids with the
connections. Do not use any cleaning agents containing alcohol or
solvents. Wipe down the instrument with a disposable cloth.
