4.3 Carrying out an automatic 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. Remove the mouthpiece (order no. 68 10 690 "Standard",
68 11 055 "with non-return function") from the packaging.
For reasons of hygiene, leave the protective wrapping around the
mouth contact area until the mouthpiece is firmly attached to the
instrument. Attach the mouthpiece at an angle to the mouthpiece
receptacle and press it into the receptacle. The fluted markings
(press-on surface) on the mouthpiece face upwards while this is
done. The mouthpiece audibly snaps into place (see page 2).
