The BACTRACK® B70 Breathalyzer is a professional alcohol
screening device, used for the detection of alcohol in the breath.
The BacTrack provides a digital result, indicating the ap-
proximate Bac (Blood alcohol content) of the test subject. The
BacTrack is powered by two aa batteries and is very easy to
use. simply turn on the unit and begin testing your alcohol level
in a matter of seconds. however, before you begin testing, there
are a few things you should know. Please take a moment to
read your owner’s manual in its entirety and familiarize yourself
with the BacTrack.
congratulations on your purchase of the
BacTrack® B70 Breathalyzer! Your new
alcohol tester estimates Blood alcohol
content in seconds. For your convenience,
we’ve provided simple instructions to get
you started.

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 concentra-
tion 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.

The alcohol concentration in the breath is related to that in the
blood, and because of this, an individual’s Bac can be deter-
mined 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 ap-
proximately the same amount of alcohol as 1 ml of blood.
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 readjust from the glare
Alcohol is a Drug
some mental (brain) impairment can occur when you have
been drinking, including:
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 (convert-
ing it into water and carbon dioxide). coffee, food or any other
“cure” will not sober you up. Only time will do that.
• reduced awareness of danger
• Becoming overly confident and reckless
• difficulty in making decisions
• reduction in balance
• slowed reflexes
• Impaired 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 impor-
tant 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.
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.

Calibration Instructions
VerIfICaTIOn and CalIbraTIOn
Please visit www.bactrack.com or call 877-334-6876 for informa-
tion on how to get your BacTrack Breathalyzer recalibrated.
The BacTrack Breathalyzer 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 users’
breath samples to these baseline values.
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.
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.

by khn solutions within the warranty Period, at its option, khn
solutions will either (1) repair the product, (2) exchange the prod-
uct with a product that is new or which has been manufactured
from new or serviceable used parts and is at least functionally

price of the product. when a refund is given, the product for
which the refund is provided must be returned to khn solutions
and becomes khn solutions’ property. This warranty is limited
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.

Exclusions, Limitations, and Disclaimers
khn solutions makes no warranties, express or implied, as to
the ability of this product to determine whether, or the extent to
which, a test subject’s mental or physical functioning, or judg-
ment, may be impaired by blood alcohol including whether the
test subject is intoxicated under any definition of that word. khn
solutions expressly disclaims any liability for direct, indirect, in-
cidental, special, or consequential damages of any nature under
any legal theory. any act or failure to act based on a reading
from this product shall be at the test subject’s or user’s own risk.
khn solutions assumes no responsibility for consequences to
or of test subjects who use this product and later are shown to
have been under the influence of alcohol or to have had their
judgment or any mental or bodily function impaired by alcohol.
correlation between breath alcohol content and blood alcohol
concentration depends on many variables, including environ-
mental factors (such as air quality, wind, humidity, temperature,
etc.) and health conditions of the test subject. a low Bac reading
does not mean that the test subject’s physical or mental perfor-
mance or judgment (including reaction times) can respond to an
emergency. The concentration of alcohol in the blood of a test
subject cannot be exactly determined by using a breath alcohol
screening product.
