InTrOduCTIOn
The BACTRACK®Select S50 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 12. 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 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 readjust from the glare
Some mental (brain) impairment can occur when you have been
drinking, including:
Reduced awareness of danger•
Becoming overly confident and reckless•
Difficulty 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.

* 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 above.
**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 a level of 0.04% or lower. It is never safe to drink
any amount of alcohol and drive.

STEP 3: When the countdown approaches
10, begin to inhale a deep breath.
STEP 4: When the countdown reaches zero,
the READY light will flash and two beeps
will sound. Blow hard, continuously, for five
full seconds. While a user is blowing, the
BACTRACK will sound a continuous tone.
Keep blowing until two beeps are heard.
STEP 5: When finished taking a breath
sample, the BACTRACK will circle the outer
LED fields for three seconds while analyzing
the breath sample.
STEP 6: Once the sensor technology has
analyzed the breath sample, the estimated
BAC (Blood Alcohol Content) value is
flashed on the screen.
The test result will be displayed for 10 seconds. Then the
BACTRACK will beep five times before powering off.
If the BAC reading is over 0.05%, the red WARN lamp
will illuminate and a rapid beep alarm will sound.

Understanding BAC Results
The displayed result is an estimate of the test subject’s BAC.
A breath alcohol tester cannot determine the exact BAC in the blood
of the test subject. Correlation between BrAC and BAC depends on
many factors, such as temperature and health conditions. Therefore,
only use this device as a tool to screen for the presence of alcohol.
Many people consider a 0.02% or greater a positive test for alcohol
in “zero tolerance” screening. Most states have 0.08% as the legal
BAC limit for tasks such as operating a motor vehicle. Some states
prohibit driving commercial vehicles or any vessel with a 0.04%
BAC or higher. Many states and countries prosecute individuals for
driving under the influence at any level.
Alerts
Battery Low: The battery power is low.
Please replace the batteries.
Flow Error: The breath sample was not
sufficient. Please repeat the testing process,
ensuring a continuous, 5 second breath
sample.
Time Out: If the user does not blow within
10 seconds, the unit displays [Out] and
shuts down.
Calibration: The unit requires recalibration or
maintenance. Please refer to the Verification
and Calibration section of this manual.

VerIfICaTIOn and CalIbraTIOn
The BACTRACK Select S50 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.
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 provid-
ing any test results, or provides unusually high or low test results,
the product should be recalibrated by a trained professional.
The product should be recalibrated at least every six to twelve
months depending on frequency of use and operating condi-
tions. 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 or call 877-334-6876 for
information on how to get your BACTRACK Breathalyzer recali-
brated.
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.

purchaser (“Warranty Period”). Except as provided in the preced-
ing sentence or applicable law, KHN Solutions provides this
product “as is”. If a defect arises and a valid claim is received
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
equivalent to the original product, or (3) refund the purchase
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
to the original end-user purchaser and is not 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 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.
KHN Solutions does not warrant that the operation of the product
will be error-free. KHN Solutions is not responsible for any conse-
quences arising from failure to follow instructions or relating
to the product’s use. This warranty does not apply: (a) to conse-
quences caused by accident, abuse, tampering, misuse, flood,
fire, earthquake or other external causes; (b) to consequences
caused by operating the product outside the permitted or
intended uses described by KHN Solutions; (c) to consequences
caused by service performed by anyone who is not a represen-
tative of KHN Solutions or a KHN Solutions Authorized Service
