IMPORTANT INFORMATION
If you do not follow the instructions for use your test results may be
inaccurate and your warranty may become void.
For most accurate results, it’s important to wait at least 20 minutes after smoking, eating or drink-
ing before testing. This is a universal principle for all breathalysers, not just yours. The reason being
is that if you have recently consumed alcohol, the residual alcohol in your mouth is very high and
can cause a false reading. Additionally, waiting 20 minutes allows the alcohol to be absorbed from
your stomach into your bloodstream, contributing to more accurate test results.

PARTS OF YOUR BREATHALYSER
AlcoLimit’s Flow Control Technology checks the ow rate of your breath. An
adequate air sample must be received before it will provide you with a reading.
This is just one of the safety measures built into the AlcoLimit range.
AlcoLimit’s Intelli-sensor Recognition Technology checks the sensor condition
every time you use your breathalyser. Stability of the sensor is analysed and an
indication will be given if the sensor needs recalibration.

USAGE
First, place 2xAAA batteries (supplied) into your ALCOLIMIT DEFENDER.
Slide the rear tab across to release the
battery compartment cover and slide it
downwards to remove.
Ensure the batteries are inserted in
the correct direction.
1. To turn your ALCOLIMIT DEFENDER on, depress the ON/OFF button for 2 seconds until
the screen turns on.
2. The unit will commence a warm-up process.
Purge cycles and circuit tests are taking place during this time. This process generally takes 30
seconds but can last 2 minutes.
3. The unit is ready when two beeps sound and the word bLo will appear on the display.
If you don’t blow into the breathalyser within 20 seconds it will turn off.
4. Attach the mouthpiece tube and blow one consistent deep breath into the
sensor. There will be a beeping noise while you are blowing.
A full lung of air is required. Once your ALCOLIMIT DEFENDER has received enough air-
flow you will hear a double click signalling you to stop.
If inadequate airflow is received, the word FLo will appear on the screen. Do not block the air
hole on the opposite side of the mouthpiece while testing as this will affect the airflow.
5. A circling line will appear on the display while the breathalyser is analysing your breath
sample. Your %BAC result will then be displayed on the screen.
The display shows only 3 digits to the right of the decimal place.
For example ‘050’ indicates ‘0.050%BAC

0.400 upwards ‘HOT’ will appear on the screen indicating the maximum level

RETESTING
Press the ON/OFF button as soon as the Red or Green LED light turns o. The breathalyser
will then start the countdown for the next test.
To retest, if your AlcoLimit DEFENDER has turned itself o, depress the on/o button, and
wait for it to warm up again.
When high alcohol readings are received, retesting should be spaced 3 minutes apart to
allow all alcohol vapour to be eliminated from the sensor.
DISPLAY & INTERPRETATION
Your %BAC will be displayed on the screen for 20 seconds after which your ALCOLIMIT
DEFENDER will turn itself o.
This device is a 0.05% BAC device (0.05%BAC is equal to 0.05grams of alcohol per 100ml of
blood).
Australian & New Zealand Customers: The drink driving cut-o for people on a full licence
is 50mg per 100ml of blood. This equates to 0.05%BAC.
This is current as at April 2015. The Australian & NZ Govts. may change this level in the future
so please check before driving.
PLEASE NOTE: Alcohol vapour on your breath will cause a higher reading. We recommend
having a glass of water prior to testing and waiting at least 20 minutes after your last drink
for accurate results. Not waiting the required 20 minutes will saturate the sensor unneces-
sarily and may cause sensor damage. This is not covered under your warranty.
Please always wait 20 minutes after consuming any alcohol to avoid this problem.

RECALIBRATION
The calibration period of ALCOLIMIT DEFENDER is 1 month or 500 uses, whichever comes rst.
A specially calibrated alcohol simulator is used to recalibrate the ALCOLIMIT DEFENDER and the
electronics need to be reset during recalibration, do not attempt to service it yourself.
If you receive erratic or high readings your breathalyser may need recalibration.
If you have any doubt about the readings you are receiving from your ALCOLIMIT DEFENDER then your
breathalyser may need recalibration.
Periodic recalibration is required because over time breath alcohol testing devices may drift from their
calibration setting even when not used.
Your ALCOLIMIT DEFENDER is a sensitive instrument. Unlike other electronic devices, your breathalyser
shouldn’t be ignored for long periods of time. The sensor inside it is delicate and can dry out if left un-
used for too long. In order to keep it in good working condition, we recommend that you blow into it at
least once a month, even if you don’t plan on using it. Breathing into the unit regularly keeps the sensor
moist and in good working order. Sensors that dry out can sometimes require more frequent calibration.
