USAGE
First, place 2xAAA Alkaline 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
