3.2 Intended use

WARNING
Small parts of the instrument may become detached and be swallowed.
►The instrument is not intended for children under 3 years.
4.1 Prerequisites for use
The instrument is factory-calibrated when delivered. If the calibration
date is longer ago than 12 months, the instrument should be calibrated,
e.g. by DrägerService. Optional: if the calibration date has been
exceeded, an error message is displayed after the startup screen.
After the last alcohol intake, wait approx. 15 minutes before a
measurement is carried out. Alcohol residues that are still in the mouth
may cause incorrect measuring values. This may also occur due to 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!

4.2 Carrying out a breath sample
A new mouthpiece must be inserted for each test subject.
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.
1. Insert a new mouthpiece (order no. 83 25 250) in the mouthpiece
receptacle (see page 2).
2. Keep the button pressed for approx. 1 second until the startup
screen is displayed.
3. READY is displayed after approx. 4 seconds. The instrument is
ready to use.
4. Blow evenly and without interruptions into the mouthpiece.
Do not cover the outlet opening on the mouthpiece with your hand.
A continuous tone is sounded.
The test result is displayed after 3 to 25 seconds (depending on
the instrument temperature and the measured concentration).
Carry out another measurement
To prepare a new measurement, press the button briefly.
During the recovery time of the sensor (see "Technical data" on
page 10) is READY displayed.
