USING THE UNIT
cycles may be required if saturation is
extensive (see Additional Information).
2. Blow into the vent
Blow continuously for about 5 seconds,
until the unit beeps 3 times before display-
ing the results. Immediately as you start
to blow,
“
Err
”
(Error) flashes until the
unit beeps 3 times. Blow very gently from
between your lips, as if cooling a spoonful
of soup. A distance of about one inch (2-3
cm) between the vent and the mouth is sug-
gested. (See
figure A.
)
Note: If you do not blow at all, or if
you stop blowing before you hear 3
beeps, the LCD flashes “
Err
” to indicate
that you did not apply any or sufficient
breath through the vent. If so, ignore the
results and repeat the process.
3. Read the results
The %BAC results are displayed on the
LCD for about 5 seconds after the read-
ing is taken. The results then flash for a
few seconds until the unit turns off auto-
matically.
The results are shown in increments of
0.01, ranging from 0.00 to 0.12. Results
greater that 0.12 %BAC are displayed as
“
+.12
”.
