urated. Simply reactivate the unit to
perform another warm-up countdown
cycle. If “SAT” appears again, repeat
this process as many times as neces-
sary until “SAT” no longer appears.
In most instances, 2 or 3 reactivation
cycles should clear the “SAT” mes-
sage. More reactivation 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 dis-
playing 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 suggested. (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.
