INTRODUCTION
The BACtrack® is an alcohol screening device, used for the
detection of alcohol in the breath. The BACtrack provides
a digital result indicating the approximate BAC (Blood
Alcohol Content) of the test subject. The BACtrack is
easy to use; simply turn on the unit and begin testing in
a matter of seconds.
Before you begin testing, please read this manual in its
entirety and familiarize yourself with the BACtrack.
ALCOHOL AND ITS EFFECTS ON THE HUMAN BODY
Alcohol is absorbed from the mouth, throat, stomach and
intestines into the bloodstream.
Alcohol ingested by the human body can be detected in the
breath because of its presence in the bloodstream.
Alcohol cannot be digested and it cannot be chemically
changed in the bloodstream. As the blood flows through
the lungs, alcohol in the bloodstream moves across the
membranes of the lung’s air sacs (alveoli) into the air. The
concentration of the alcohol in the alveolar air is directly
related to the concentration of the alcohol in the blood. As
the alveolar air is exhaled, the alcohol in it can be detected
by the breath alcohol testing device.
ENG 2
The alcohol concentration in the breath is related to that in
the blood, and because of this, an individual’s BAC can be
determined by measuring alcohol in the breath. The ratio of
breath alcohol to blood alcohol is generally estimated to be
2,100:1. Therefore, 2,100 milliliters (ml) of alveolar air will
contain approximately the same amount of alcohol as 1 ml
of blood.
ALCOHOL IS A DRUG
Alcohol is the chemical (ethanol or ethyl alcohol) resulting
from the fermentation of grapes or grain. Alcohol is
absorbed directly into your bloodstream. From your
bloodstream, the fluids in your body tissues absorb the
alcohol. Your brain is made up of a large concentration of
fluids and will absorb a large amount of any alcohol you
drink. Your liver eliminates the absorbed alcohol at its own
rate of time and nothing you eat or drink can speed up
the process. Your liver does this by oxidizing the alcohol
(converting it into water and carbon dioxide). Coffee, food or
any other “cure” will not sober you up; only time will do that.
HOW DOES ALCOHOL AFFECT MY BODY?
Alcohol is a depressant. It has a relaxing effect on the
muscles in your body. The muscles of your eyes relax and
lose focus. Your eyesight will become fuzzy and you may
experience double vision. Brain activity is slowed. Your
judgment, reflexes, and coordination are all negatively
affected.
Some vision impairments that occur when you have been
drinking include:
• Narrowing of your field of vision
• Reduction in your depth perception
• Decreased ability to see in darkness
• Increased sensitivity to glare and a longer time for your
eyes to r
eadjust from the glare
Some mental impairment can occur when you have been
drinking, including:
• Reduced awar
eness of danger
• Becoming overly confident and r
eckless
• Dif
ficulty in making decisions
• Reduction in balance
• Slowed r
eflexes
• Impair
ed judgment
HOW DOES ALCOHOL AFFECT MY DRIVING?
We can’t emphasize enough how dangerous it is for you
to drink and drive. Your vision and your brain are the most
important factors in driving safely. If you jeopardize either by
drinking, and then you drive, you are likely to be involved in a
serious or fatal collision.

ENG 4
Do not use your BACtrack as a tool to determine whether you
should operate a motor vehicle or equipment, or perform any
other dangerous act. Do not drink and drive. Always have a
designated driver when alcohol is being consumed.
EFFECTS OF ALCOHOL*
0.02-0.03% BAC Slight euphoria. Loss of shyness.
Depr
essant effects are not apparent.
Impairment possible in some individuals.
0.04-0.06% BAC
Feeling of well-being, r
elaxation, lower
inhibitions and sensation of warmth.
Euphoria. Some minor impairment of
reasoning and memory. Lowering of
caution. Driving skills may be impair
ed
at this level of intoxication.
0.07-0.09% BAC
Slight impairment of balance, speech,
vision, reaction time, and hearing.
Euphoria. Judgment and self-contr
ol are
reduced. Caution, reason and memory
ar
e impaired. Driving skills are always
impaired at this level of intoxication
and higher
.
0.10-0.12% BAC Significant impairment of motor
coor
dination and loss of good judgment.
Speech may be slurred. Balance, vision,
r
eaction time and hearing will be
impaired. Euphoria.
0.13-0.15% BAC Gross motor impairment and lack of
physical control. Blurred vision and
major loss of balance. Euphoria is
reduced and dysphoria (anxiety,
r
estlessness) begins to appear.
0.16-0.20% BAC Dysphoria predominates. Nausea
may appear
.
0.25% BAC Need for assistance in walking.
T
otal mental confusion. Dysphoria
with nausea and some vomiting.
0.30% BAC
Loss of consciousness. Onset of
coma. Possible death due to
r
espiratory arrest**.
* The effects of alcohol intoxication are greatly influenced by individual variations
among users. Some users will be intoxicated at a much lower BAC than shown
on the previous page.
** Death can occur at a lower BAC in some individuals.
The generally accepted legal standard for alcohol intoxication in Canada/the
United States is 0.08%. However, your driving skills can be impaired at any level
above 0.00% BAC. It is never safe to drink any amount of alcohol and drive.

IMPORTANT!
For most accurate results, it’s important to wait at least 20
minutes after smoking, eating or drinking before testing.
This is a universal principle for all breathalyzers, not just yours.
The reason being is that if you have recently consumed alcohol, the residual alcohol in your mouth is very high and can
cause a false reading.

flash on the screen. Blow steadily and consistently
for six seconds thr
ough the mouthpiece - do not
blow as hard as possible. The BACtrack emits a
beeping sound during the br
eath sample. Stop
blowing when the beeping sound stops. There is
a click at the end - that’
s the air pump pulling air
across the sensor.
STEP 6:
Once the sensor has analyzed the br
eath sample,
the estimated BAC value is displayed. The BACtrack
will tur
n off automatically in 10 seconds. You can
also turn off the breathalyzer during the countdown
by pr
essing and holding down power for 2 seconds.
The front blue LED light will turn off.

VERIFICATION AND CALIBRATION
The BACtrack is calibrated during manufacture using
advanced alcohol simulation equipment. Known alcohol
concentrations are passed through the sensor to set baseline
values for testing. During testing, the unit compares breath
samples to these baseline values.
The accuracy of breath alcohol testers can fluctuate after six
to twelve months of normal use depending on the number of
tests performed and operating conditions.
If this product is providing inconsistent test results, is not
providing any test results, or provides unusually high or low
test results, the product should be recalibrated immediately
by a trained professional.
The product should be recalibrated at least every six to twelve
months. If the product is used every day, it may need to be
recalibrated as frequently as every month.
CALIBRATION INSTRUCTIONS
Please visit www.bactrack.com/calibration or call
877.334.6876 for information on how to get your BACtrack
recalibrated.
During recalibration, a professional technician will reset the
sensor baseline values and also perform a full diagnostic
check to ensure the accuracy and reliability of the product.
