Preparation
INSTALLING BATTERIES
ATTACHING A MOUTHPIECE
Remove the mouthpiece from its wrapper, making
sure not to touch the end which the subject will be
blowing into.
Attach the mouthpiece to the port on the back of
the FC20.
Line up the mouthpiece port over the hole in the
back of the mouthpiece. Press in place.
Ensure it is snuggly fit.
Press in and down on the battery door located on
the back of the FC20 in the direction of the arrow.
Install the 4 AA Alkaline batteries in the direction
of the symbols in the battery case.
Close the case by pushing up on the battery door

OBSERVING THE SUBJECT
TURNING THE FC20 ON & OFF
Preparation
Press and hold the Power button on the
bottom of the unit until it beeps. The
FC20 performs an automatic internal
diagnostics check.
To turn the unit off, press and hold the
Power button until it beeps. The unit
will shut down.
The FC20 provides a highly accurate reading of
breath alcohol acquired by sampling deep lung
air. However, the reading can be corrupted by
residual mouth alcohol.
To prevent mouth alcohol from affecting a test,
make certain that the subject is not allowed to put
anything in their mouth for the 15 minutes prior to
taking a test.
If the subject just took a drink, a 15 minute obser-
vation period in which they are not permitted to
put anything in their mouth should be observed
before testing. This will ensure all residual alcohol
from any source is completely dissipated and test
results will be valid.

CONDUCTING AN AUTOMATIC TEST
Breath Testing Modes
The FC20 is capable of conducting 3 distinct types of breath
tests.
èAutomatic Test is the most used and highest accuracy test.
The FC20 monitors the subject’s breath and automatically
takes the sample near the end of the breath flow.
èManual Test is normally used only when the subject is una-
ble to provide a sufficient air sample for the automatic test.
èPassive Test is a quick screen to detect alcohol but is not
designed to quantify the results. Passive results are report-
ed as POS if alcohol is detected, NEG if alcohol is not de-
tected. In this mode, no mouthpiece is required.
