3. Preparing the unit for first time use

Activating the sensor

Before first use, or after an extended period of storage without

use you must activate the sensor.

1) To activate the sensor you need an alcoholic liquid of 5-7% volume. In the

UK pre-made drinks of this volume are difficult to find. We suggest the

mixing a small amount of white wine and water in a ratio of 1 part wine to 1

part of water.

2) In the box there is a small plastic cap. Put a small drop of the liquid you

have mixed in step 1 in to the cap. Place the cap into the blow tube hole

on the AlcoSense Lite as shown in the diagram below.

3) If you have inserted batteries already, remove them from the back of the

unit, press the power key once, then re-insert them. The ASC (Auto Sensor

Clean) will start. Do not press any keys as this will cancel the ASC.

4) Put the unit down and wait 10 minutes. Two beeps will be heard to

indicate the start of the ASC. After 10 minutes the AlcoSense Lite will beep

meaning that the ASC is finished.

5) When the ASC is complete, leave the cap in the breathalyser and press

the power key as if you were performing a breath test (see page 8 of the

manual). When the AlcoSense Lite displays Blow on the screen, hold down

the Blow button for 5 seconds, until a beep is heard.

If the result shown on screen is 0.2 or higher, or just HI then the

sensor is activated and the unit is ready to be used. Remove the cap from the

breathalyser and you can use the pipette to blow fresh air through the

breathalyser blow hole. PLEASE NOTE that the breathalyser may

temporarily read slightly high for a couple of hours after activation, for

example you may see a positive reading when you haven't drunk any alcohol

- this will pass after a couple of hours.

If the result is ERR, please repeat step 5 again. This could be caused by

pressing the blow key too late or not for long enough.

If the result is LO please perform an Auto Sensor Clean (see page 7 of

the manual), then repeat the above steps to activate the sensor again. If

it is still showing LO after repeating the process please call us on 0800

Automatic Sensor Clean (ASC) Function

The ASC Function cleans the sensor inside the system and removes any

contaminants from it (for example, oxidisation if it has not been used for a

period of time or residue left from previous tests). We recommend you

perform an ASC every 4 weeks. To perform an ASC please do the

following:

1. In a clean air environment, remove the batteries from the back of

the unit, wait 5 seconds and re-insert them. The ASC will automatically

start. Do not press any keys as this will cancel the ASC.

2. Put the unit down and wait 10 minutes. Two beeps will be heard to

indicate the start of the ASC and ASC will flash on the screen. After

10 minutes the AlcoSense Lite will beep meaning it is finished.
