The LifeGuard is intended to measure alcohol in
human breath. Measurements obtained from this
device are used in the diagnosis of alcohol intoxica-
tion. The LifeGuard is intended to be used by the
general adult population and by qualied person-
nel, such as physicians, nurses, and technicians. The
LifeGuard product is intended to be used by adults
(age 21 and over) in measuring alcohol intoxication
in themselves or others, and is intended to be used
in both home (over the counter) & clinical settings.
It is very important to have the instrument cali-
brated as recommended in this operators manual
on page 10. Failure to do so may result in readings
that are inaccurate.

Precautions
1. DO NOT DRINK AND DRIVE! - It is strongly
recommended that no vehicle or machinery be
operated after alcohol consumption. Even small
quantities of alcohol can cause impairment. The
LifeGuard product should not be used as a tool
to determine if it is safe for the user to operate
machinery or a motor vehicle.
2. Wait at least 15 minutes after drinking, smoking
or inserting anything in your mouth before
taking a breath test.
3. The LifeGuard product is intended to be used by
adults (age 21 and over) in measuring alcohol
intoxication in themselves or others.
4. The LifeGuard is not to be used in potentially
explosive environments such as an oxygen tent.
5. Do not blow smoke into the mouthpiece as it
may damage the sensor.
6. Replace the battery when the low battery icon
is displayed.
Preparation
Battery Installation
The LifeGuard is designed to operate from a com-
mon 9 volt (EN22 / 9V) alkaline battery. Remove
the battery door by pressing down slightly and
sliding the door toward the back of the unit. Install
the battery following the polarity markings on
the inside of the battery housing. To close, apply a
small amount of pressure on the battery while slid-
ing the battery door toward the front of the
instrument.
7. We recommend storing the LifeGuard in
temperatures between 32o- 122oF (0o - 50o C).
8. No user serviceable parts inside. To be serviced
only by an authorized LifeGuard technician.
9. If instrument will not be used for more than 6
months remove battery to avoid damage to the
instrument caused by leaking battery acid.

This device has been tested following NHTSA/DOT
procedures. In that testing protocol, the accuracy of
this device was established at Blood Alcohol Concen-
trations of 0.008 and 0.032. Lifeloc performs & validates
additional testing at concentrations of 000 - .400 BAC.

1. Turn-on the LifeGuard by momentarily
pressing the power button. The instrument
will initiate a self-test and then display the
ready icon.
2. For maximum convenience, the LifeGuard uses
a dual-mode mouthpiece design that can be
operated in two ways according to your
testing circumstances.
2a. Permanent (fold-away) Mouthpiece
The permanent (fold-away) mouthpiece con-
veniently folds into the LifeGuard when not in
use. The fold-away mouthpiece is intended for
self-testing or repeated testing of the same
subject. When not in use it folds away until
you need it.
The Permanent (fold-away) mouthpiece is
designed to remain attached to the Lifeguard
under normal use; however it can be removed
for cleaning. Do not discard the permanent
(fold-away) mouthpiece. It is an integral part
of the Lifeguard and is used for both personal
testing and in the testing of others.
If the fold-away mouthpiece becomes con-
taminated with food, dirt or other foreign
matter it should be cleaned to prevent con-
tamination of the internal breath path and fuel

Cause & Course of Action
Ready - Begin blowing into the unit.
Low Battery - The battery needs to be
replaced.
Wait - The fuel cell is not yet ready for a
test.
Temperature - The internal temperature
of the instrument is outside of its testing
range.
Calibration Due - Due date appears when
turned on within 35 days of requiring cali-
bration & when calibration is overdue.
Insucient breath - Subject blew less
than 1 liter of breath. Try again and blow
steadily for at least 4 seconds.
Insucient breath - Subject didn’t blow
long enough. Try again and blow steadily
for at least 4 seconds.
Subject is inhaling. Try Again.
Interference - High levels of electronic
interference are detected. Try the test in a
dierent location.
Excessive Alcohol - Detector sensed
alcohol levels above .400 BAC.
Excessive Condensation - Let the unit rest
for 30 minutes.
Self-test error - Instrument may need
servicing. Contact LifeGuard Tech Support.
Over Range - Detector sensed alcohol
levels above .400 BAC

cell. Do not immerse the Lifeguard unit
in water. To clean the permanent (fold-away)
mouthpiece, tilt the mouthpiece to a 45o
angle towards the closed position and gently
pull the mouthpiece up and away from the
unit, as shown in the diagram below. Do not
force or bend the mouthpiece over the edge
of the Lifeguard to remove.
Clean the permanent (fold-away) mouthpiece
with warm water and dish detergent as you
would with eating utensils. Allow to thorough-
ly dry and re-attach to the Lifeguard.
If the mouthpiece becomes damaged or lost,
additional permanent (fold-away) mouth
pieces can be ordered from
www.lifeguardbreathtester.com or your dealer.
2b. Disposable (slip-on) Mouthpiece
Disposable (slip-on) mouthpieces are for one
time use. Each mouthpiece is individually fac-
tory sealed until the moment you need it. Fold
out the permanent (fold-away) mouthpiece
and attach a disposable (slip-on) mouthpiece
over the permanent mouthpiece (see
components diagram on page 3). You are now
ready to take a test.
3. The subject being tested should not eat, drink,
smoke or put anything in their mouth for 15
minutes prior to taking a breath alcohol test.
Failure to comply with this instruction may
result in inaccurate readings.
4. Instruct the subject to take a deep breath and
blow rmly and steadily into the LifeGuard for
a minimum of four (4) seconds. The instrument
will provide a steady tone if the subject is
blowing correctly.
If the subject blows for less than 4 seconds
the LifeGuard will display the message to
“Blow Longer”. Instruct the subject to blow
steadily for at least 4 seconds.
While the subject is blowing, the LifeGuard
will display a graph of the breath ow and
the total liters of breath. This allows the
observer to visually monitor the subject’s
breath test. The instrument automatically
measures the subject’s breath ow and trig-
gers the test when a satisfactory deep lung
breath sample is provided.
After a successful test the unit displays a visual
graph of the fuel cell reading while it is calcu-
lating the BAC produced from the test. The
graph is not a substitute for the subject’s
BAC reading.
5. Immediately after a negative test or within
5-10 seconds after a positive test, the
LifeGuard will display the test result.

Calibration
All breath testers require periodic calibration to
maintain their accuracy. Your LifeGuard is designed
to be calibrated by a factory certied calibration
technician. It is recommended that your LifeGuard
be calibrated at least once every 12 months.
