Limits
AUSTRALIAN BLOOD ALCOHOL LIMITS: Adult License 0.05% BAC
Some drivers are restricted to lower levels of BAC. Please refer to your local
transport authority for your correct limit. If in any doubt do not drink and drive.
The safest level when driving is none at all. Alcohol impairs your judgement and
can make you drowsy or sleepy.
Disclaimer
PLEASE NOTE:
This product must be used in accordance with the instructions in this manual
and – in particular - must not be allowed to get wet.
This product is intended to provide the user with an indication of alcohol on the
breath. However, neither the manufacturer nor the supplier gives any warranty
(express or implied) that the product can give any indication of blood alcohol
level.
A person’s BAC (Blood Alcohol Concentration) can only be accurately measured
by the administration of a blood test. This product only measures breath alcohol
content which, in turn, only gives an approximately indication of blood alcohol
concentration.
In these circumstances the user of this product should not rely on the
information provided thereby as an accurate indication of his blood alcohol
concentration or of his level of intoxication or of his fitness to drive and in
particular should not take any action in reliance on such information as the
product can provide no more than an indication of alcohol on the breath.
If the user of this product makes any decision or takes any action based on the
use of the product such decision or such action shall be at the sole risk of the
user and neither the manufacturer nor the supplier assumes any responsibility
for such decision or action.
In particular, neither the manufacturer nor the supplier shall be in any way
liable if the user of the product asserts that the product led him to believe that
he was fit to operate a motor vehicle and is subsequently found not to be so fit.

Recalibration & Service
The AlcoSense®Nexus uses a fuel cell sensor to measure breath alcohol levels.
Depending upon the amount of alcohol registered by the sensor after a period of
time, it will require recalibration.
Andatech recommends the AlcoSense®Nexus to be calibrated every 6 months
or after 500 uses, whichever comes first. To maintain it to Australian Standards,
calibration every 6 months is required.
Warnings
a. Allow at least 20 minutes after eating or drinking before testing. Any type of
alcohol remaining in the mouth of saliva may interfere with proper testing
and requires about 20 minutes to disperse. This includes alcohol-based
mouthwash or similar products.
b. Avoid testing in high wind conditions or in poorly ventilated or enclosed spaces.
Poor ventilation may also lengthen the time required for warm up between tests.
c. Do not blow smoke, saliva or other contaminants into the mouthpiece, as the
sensor may become damaged. Wait at least 20 minutes after smoking before
conducting a test.
d. Do not use the breathalyser as a tool to drink and drive.
e. Do not blow fluid into the instrument as it will damage the sensor and void your
warranty.
f. Do not store in an extreme environment where high temperature or high
humidity exists. Keep out of the reach of children.
g. To maintain accuracy, we recommend professional recalibration every 6 months.
h. Blood alcohol concentration can continue to rise for up to 2 hours after the
cessation of drinking. If a caution result or a result is close to the designated
BAC, it is recommended to wait and retest after 20 minutes.
i. It can take 10 hours or more for the alcohol level to return to a zero after a high
blood alcohol level has been reached. A further test should be carried out later
in the day of the following morning.
