Redundant Buttons
In the event that any of the 3 buttons used to operate the unit becomes inoperable, the
remaining buttons will assume that function, as follows:
• If the LEFT button is not working, use the RIGHT button to scroll all the way around.
• If the RIGHT button is not working, use the LEFT button to scroll all the way around.
• If the TRIGGER is not working at any time, press BOTH the LEFT AND RIGHT buttons at
the same time for TRIGGER functionality.
Personal Identification Number (PIN)
When the unit was installed, you were issued a 4 digit PIN. The purpose of this number is to
confirm timing and coordination and ensure only you or persons that you intend are able to
operate the unit. Before taking any Standing BAC Test (Start, Arrival or Engine Off) you will be
asked to enter your PIN. Depending on how your unit is configured, you may also be asked to
enter your PIN when the unit wakes up.
To enter PIN, use the BACK or NEXT buttons to scroll to the desired digit, then press the
TRIGGER to enter. Repeat for each of the next 3 digits.
Start Test
This menu option is used to take the test that allows you to start your vehicle. To take this test,
press the TRIGGER (See Section 6 for further instructions).
Adjust Volume
This function allows the user to adjust the audio volume when the vehicle is NOT RUNNING. To
adjust the volume, press the TRIGGER from this option, and the use the LEFT (DOWN) and
RIGHT (UP) buttons until the desired volume level is achieved, and then press the TRIGGER to
set the volume to that level.
Select Language
This function allows the user to select the language that will be displayed in the text and played
for the audio. To select another language, press the TRIGGER from this option, and use the
LEFT (BACK) and RIGHT (NEXT) buttons until the desired language is displayed. This unit
offers English and Spanish. When the desired language is displayed press the TRIGGER to set
the language.
Remove Unit
NOTE: AS AN ANTI-THEFT MEASURE, IF THE SAMPLE HEAD IS REMOVED WITHOUT
SELECTING THIS OPTION, THE VEHICLE SIREN WILL SOUND.
This option allows the user to remove the Sample Head from the vehicle if desired. This may be
done for the following reasons:
• To prevent theft.
• To protect your vehicle battery during long periods of inactivity (beyond 5 days), such as
vacation for several weeks.
• To protect the device from extreme cold temperatures.
To remove the Sample Head, press the TRIGGER from this option, and then remove the unit
when instructed to. Do this by grasping the knurled part of the connector barrel only, and pull it
straight back until the connector releases.
