1.
The TAB will turn “ON” automatically, when the display shows “Fit Mouthpiece, Give Sample”
follow the same procedure to provide a breath sample as described on page 2.
2.
The TAB analyses the breath sample as before and the VBS records the result.
Should the “Random Testing” option be selected at installation, while the vehicle is on route, the VBS buzzer
will sound as a request for a random breath sample. (This will be randomly repeated at any stage of the
journey).
RANDOM “ON THE ROAD” TESTING
Should no breath sample be supplied within a preset period, the buzzer will stop and the RED LED will start to
flash at a faster rate continuously until a valid sample is presented.
NOTE : Failure to provide a breath sample for analysis during random testing or providing a
sample that exceeds the predetermined level, will not cause the vehicle to stop, however, failure to
provide a breath sample or providing a sample that exceeds the predetermined level will cause a
non event to be presented at the GSM output to be sent if the GSM module is connected (Optional).
If the vehicle is stopped and the ignition turned off, it will be blocked immediately.
DRIVER CHANGING
Should a new driver be required to take over driving responsibilities, the
following procedure needs to be followed:
1. As the new driver takes over, the Driver Change Button must be pressed.
2.
The VBS buzzer will sound to request a new breath sample.
3.
The TAB will turn “ON” automatically, when the display shows “Fit Mouthpiece, Take Sample” follow
the same procedure to provide a breath sample as described on page 2.

The TAB analyses the breath sample as usual, the VBS records the result and the driver test timer is
reset.

If the TAB displays
"FAIL”
then it has detected alcohol in the breath at a level
in excess of the preset limit. If you have observed the points shown in the
"Before Providing a Sample" section of these instructions, then you have a
breath alcohol level above the pre-set limit. The RED LED will flash rapidly, and
the Blocking System will remain blocked, the RED LED will continue flashing
and the vehicle will not start. This event will be recorded by the VBS with date
and time. (If the optional GSM module is connected an SMS message will be
automatically sent to a mobile phone or the control centre that a failure as taken
place)
The system may also be linked to a fleet management system - ask
your service/installation centre.
You should wait for approximately 30 minutes and then provide a
further sample, by which time your body
may
have metabolised the
alcohol and reduced the level below the preset limit.
2.
If the TAB displays
"Insufficient Sample"
then one or more of
the following could be the cause of the problem.
Insufficient length of blow (Volume).
Incorrect force of blow (Too hard or too soft).
If
“Insufficient Sample”
is displayed after providing a breath sample when
the tone was heard, it will most likely be an indication of an incorrectly
positioned mouthpiece.

BASIC MAINTENANCE
Cleaning the TAB
If and when required, simply wipe over with a lightly
dampened cloth.
Calibration and Services
