Lifeloc FC20 - Turning the FC20 On and Off; Subject Observation Period

Page 9
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.
