READ THE RESULTS
The result is an estimate of the subject’s BAC. A breath alcohol tester
cannot determine the exact BAC in the blood of the subject. Correlation
between BrAC and BAC depends on many factors, such as temperature
and health conditions. Only use this device 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 prosecute individuals for driving under the influence at any
level.
ERROR MESSAGES
Error Message Cause and Course of Action
The unit displays “WARN” and plays alarm tones when
the result is higher than 0.05% BAC.
The unit did not detect an even alcohol concentration in
the breath sample. This can occur if the user varies the
blowing force when performing a test or if the exhaust port
is obstructed. Repeat operation steps 1 – 6 to perform
another test.
The unit displays “Hot” and plays alarm tones when it
has detected a very high alcohol concentration (above
0.40% BAC).
Battery power is low. Install a new 9V alkaline battery.
Note: Any of these errors will turn the unit’s backlight red.
