Track your B.A.C. – BACtrack!
The BACtrack
®
Select S80 Breathalyzer is an
alcohol screening device, used for the detection of
alcohol in the breath. The BACtrack provides a digital
result, displaying an estimate of the subject’s BAC
(Blood Alcohol Content). Before you begin testing, it is
very important to read the entire owner’s manual.
It is also very important to have the instrument calibrated
periodically as recommended on page 13. Failure to do
so may result in readings that are inaccurate.
Alcohol and its effects on the human body
When a person consumes alcohol, the alcohol is
absorbed from the mouth, throat, stomach and intestines
into the bloodstream. The alcohol in the bloodstream
exchanges with air deep in the lungs. The percent of
alcohol in a person’s blood (BAC) is proportional to
the percent of alcohol in a person’s breath (BrAC). The
BACtrack measures a subject’s deep lung air alcohol
level and converts it to the estimated BAC.
“BAC” means Blood Alcohol Concentration. It is
measured in %.
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
11
affected. Some vision impairments that occur when you
have been drinking include:
• Narrowing of your f eld 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
Some mental (brain) impairment can occur when you
have been drinking, including:
• Reduced awareness of danger
• Becoming overly confdent and reckless
• Diffculty in making decisions
• Reduction in balance
• Slowed reflexes
• Impaired judgment
Variations among individuals and other factors, such
as altitude and air temperature, affect the degree of
intoxication. Some individuals may become intoxicated
at low BAC levels. A low BAC on a breath alcohol tester
does not mean that a person’s reaction times can respond
to any emergency encountered. Individuals should not
drink alcohol and drive or use any machinery after
consuming alcohol.
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.
There is no safe way to drive under the
influence of alcohol. Even one drink can make
you unsafe.

Dose-Specific Effects
BAC
* 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
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.

PRECAUTIONS
1. Wait at least 20 minutes after drinking, eating or
smoking before testing. Not observing this waiting
period can cause inaccurate readings and damage
the sensor.
2. Do not blow smoke, food, or liquids into the
BACtrack as this will damage the sensor.
3. Do not test in areas with strong winds, smoke, or in
an area where a large amount of alcohol is being
consumed.
4. Replace the two AA batteries when the battery
indicator icon reaches one bar.
5. Send your tester in for periodic calibration service as
required. (See calibration).
6. The BACtrack Breathalyzer is designed to be used in
a temperature range of 32-104 °F (0-40 °C).
7. Avoid testing in the presence of any substances
that contain methyl alcohol, isopropyl alcohol or
acetone. These substances may interfere with the
results of the test.
8. You cannot use the results of this product in court.
9. Do not use the BACtrack as a tool to determine
whether you should operate a motor vehicle or
equipment, or perform any other dangerous act.
10. Do not drink and drive. Always have a designated
driver when alcohol is being consumed.
12
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 users’
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 depending on frequency of use and
operating conditions. We recommend sending the unit in for
calibration after 200 tests have been performed, or every 6
to 12 months if less than 200 tests have been performed. 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
Breathalyzer recalibrated. Calibrations are an important
part of the maintenance of your breathalyzer and should be
performed regularly.
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.

transferable to, or enforceable by, any subsequent owner.
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 judgment, may be impaired by blood
alcohol including whether the test subject is intoxicated
under any defnition of that word. KHN solutions expressly
disclaims any liability for direct, indirect, incidental, special,
or consequential damages of any nature under any legal
theory. Any act or failure to act based on a reading from
14
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 environmental 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 performance
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.
KHN Solutions does not warrant that the operation of the
product will be error-free. KHN Solutions is not responsible
for any consequences arising from failure to follow
