Graphics display
The illuminated display instructs the user during breath sampling, and
shows the subject’s breath alcohol reading. The small icon at the top right
shows the power unit’s charge level.
Beeper
This provides various audible tone messages to the instrument operator,
and the subject.
Breath sampling port
The port located in the top channel of the instrument is the entrance to
the fuel cell alcohol detector and to the breath flow sensor. Do not allow
fluids to enter this port, or serious damage to the instrument may result.
Disposable Mouthpiece
The disposable mouthpiece is supplied
packed in individual, hygienic wrappers. It is
fitted to the instrument by locking its
sampling port into the small hole in the side
of the tube: it may be attached either way
round, whichever is more convenient to the
operator, the subject or the situation. But
the subject MUST blow through the wide-
bore, lipped end, or the instrument’s
automatic sampling system will not operate.
