Note: The maximum reading the device can show is 0.40%. A true BAC of 0.40% or above may result in
the onset of coma or even death by respiratory arrest. A reading of 0.40% may indicate an acutely
dangerous condition, but may also indicate a sampling error (such as liquid alcohol blown into the
device). Please carefully read the
Warning section
of this manual before operating the device.
- General Information about DUI/DWI -
The legal limit for intoxication (DUI/DWI) is
0.08%
BAC across most of the USA. According to the
American Medical Association (AMA), a BAC of
0.05%
is enough to impair the ability to drive. You
should never operate a motor vehicle when you are impaired by the consumption of alcohol, drugs or
lack of proper rest.

Warnings and Precautions
WAIT AT LEAST 20 MINUTES AFTER EATING OR DRINKING BEFORE TESTING.
A breathalyzer
examines “lung air” samples, not “mouth air” to calculate alcohol content. Any “contaminants” in the
mouth, including alcohol, food, smoke, or even excess saliva, may interfere with testing. This
includes alcohol-based mouthwash or similar products.
This is the most common cause of improper
use and incorrect results.
Avoid testing in high wind or enclosed spaces. Poor ventilation may also lengthen the time required
for warm up between tests.
Do not blow smoke, saliva or other contaminants into the mouthpiece, as the sensor may become
damaged.
Do NOT use the AlcoScan AL2500 as a tool to drink and drive.
Keep out of extreme temperatures and out of the reach of children.
To maintain accuracy, the sensor inside the AlcoScan AL2500 must be recalibrated every 200 tests
or at least once a year (whichever comes first)
. Large numbers of "high positive" (high alcohol)
readings may require recalibration of the sensor much sooner than normally expected. To
recalibrate, you must mail your device to the address at the end of this manual. Please contact us
at
for details and related fees.
