Carrying out a breath sample
A new mouthpiece must be inserted for each person who provides
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.
