DRAEGER INTERLOCK® XT
OVERVIEW
What does the Draeger Interlock do?
• It allows you to start your vehicle when you blow a breath sample without alcohol.
• Use it correctly and you can continue to drive your vehicle.
How does it work?
• The system measures and records your BAC level before you start your vehicle. When
your BAC level is below the set limit, your vehicle will start. If your BAC level is too
high, your vehicle will not start.
• The system will also require you to submit additional breath tests while you drive.
• The Interlock records all BAC readings, vehicle starts, engine shut-offs, violations, etc.,
as well as the date and time of each event. A computer records these events each time
you go to the service center for a service check.
Does the device have to be serviced after installation?
• Yes! The Interlock will indicate when service is due. You will not be able to start your
vehicle if you do not have the device serviced as required.
• Make sure you get the device serviced as required. See back inside cover for your service
requirements.
IMPORTANT DO’S AND DONT’S
For correct operation of the Interlock:
• DO keep the unit clean and dry at all times.
• DO use a clean, dry mouthpiece when providing breath tests.
• DO contact your Service Technician with any questions or concerns.
• DO NOT consume alcohol, use alcohol-based products (such as mouthwash), or smoke
for 15 minutes before using the Interlock. Alcohol remaining in the mouth shortly after
drinking can produce high readings.
• DO NOT place the Interlock unit on the vehicle oor. If the device is not secured, it may
interfere with the pedals and the safe operation of the vehicle.
• DO NOT use the Interlock while driving if you are at all unsure about your safety. If you
are asked for a breath test while driving, you will have enough time to pull over, stop the
vehicle and present the breath test.
• DO NOT attempt to disable the Interlock, or fail to undergo a proper Retest. This will
shorten the service interval and these actions are recorded in memory.
• DO NOT tamper with, abuse, misuse and/or neglect the Interlock device.
NOTE:
BAC = Breath Alcohol Concentration
WARNING
Leave the tamper-evident label in place.
Any attempt to remove the label is a
violation!
WARNING
To ensure a valid breath test, you must abstain from eating, drinking any uids (with
the exception of water) or smoking for at least 15 minutes prior to providing an initial
breath test. The same deprivation period applies to the use of mouthwash, cough syrup,
other alcohol containing medication, perfumes and colognes. Because the Interlock
might require a rolling retest, you should not eat, drink (with exception of water) or
smoke while driving the car.

TAKING A BREATH TEST
At the "Ready for Test - PLEASE BLOW" prompt, take a few normal, even breaths, then….
• Take a deep breath and put your lips around the mouthpiece.
• Provide a steady blow into the mouthpiece (exhaling normally).
• As you blow into the Interlock, the buzzer will sound.
This means you are blowing correctly, so DON’T STOP.
• When the buzzer sound stops (you may hear a "click") , give an immediate short, sharp
suck back.
• Do not pause between the blow and the suck back.
The Interlock will display "Test Passed" or "TEST FAILED" if the blow pattern was correct.
TEST PASSED: If little or no alcohol is detected in the breath test, the message "Test Passed"
will appear (Figure 3). The vehicle will now start.
TEST FAILED: If alcohol is detected in the breath sample, the message "TEST FAILED" will
appear (Figure 4). The vehicle will not start.
NOTE:
You have at least a minute to start the vehicle after passing a breath test. If you
do not start the vehicle within this free start time, you must pass another test. The free start time
remaining to start the vehicle is displayed on the handset.
Do not disconnect the handset while you are driving the vehicle or while the engine is on;
this action is a violation!
DO NOT smoke
during a breath test.
Keep the handset at least
12" from radio, cell phone
or pager.

NOTE:
If you turn the vehicle's key to the "ON" position just to get enough
power to roll up your window (with no plan to drive) and you see
"PLEASE BLOW", you do not need to take the test. Simply turn key
to the "OFF" position. The initial test will be aborted.

DRAEGER INTERLOCK® XT
WHAT HAPPENS IF I FAIL THE BREATH TEST?
• If the screen shows "TEST FAILED" after the breath test, the vehicle will not start. The
screen will then display a countdown of the time before another breath test can be taken.
• If the alcohol content of your breath was very high, the device may be disabled (temporary
lockout) longer.
• Once the temporary lockout has been completed, return the ignition key to the "ON"
position. The device will prepare for another test.
• When the yellow light starts ashing and the display shows "Ready for Test - PLEASE
BLOW", try the test again.
NOTE:
Do not use mouthwash or any product containing alcohol for 15 minutes before testing.
Repeated failed tests may also result in the device going into "Temporary Lockout".
TEMPORARY LOCKOUT
What happens if the device goes into the "Temporary Lockout" mode before I start my vehicle?
• If you failed your breath test, the Interlock may enter the "Temporary Lockout" mode.
• The display will show you how much time (hours, minutes and seconds) remain in the
"Temporary Lockout" period as shown in Figure 5. The red LED light will also be on.
• After the "Temporary Lockout" is over, the device will turn itself off. If you want to try
another breath test, turn the ignition key to the "ON" position.

ROLLING RETEST
What is a Rolling Retest?
To make sure you stay sober while driving, the Interlock requires you to take additional tests
while you drive. You must give additional breath tests at random intervals – perhaps several times
before you turn off your vehicle. (See back cover for how often you will take the Retest.)
• When the Interlock prompts for a Retest, you will hear a beep and the yellow light will ash.
• The Interlock will display "Retest required - PLEASE BLOW".
• Take the breath test exactly as you do when you start your vehicle.
• Give the Retest within the specied time.
• When you see "TEST PASSED", put the device back on the Hook and Loop Tape and
continue your trip.
• The "Drive Safely!" message will return to the display and remain on the display for the
duration of the trip or until the next random Rolling Retest.
What happens if I just turn my vehicle off during the Retest?
• Once the device asks for a Retest, you must take the Retest.
• A violation will be recorded if you don’t take the Retest in the time allowed.
What happens if I don’t hear the Retest prompt?
• At certain times, the Interlock's buzzers will start beeping continuously to alert you.
• To stop the buzzers, press the OK button and take the Retest.
What happens if I don’t take the Retest in time?
• The message "Retest VIOLATION" will be displayed.
• The Interlock's buzzers will beep continuously.
• The vehicle’s horn may repeatedly honk and/or the headlights may continuously ash.
• You must pass the Retest or turn off the vehicle in order to deactivate the horn and/or lights.
REMEMBER
You have several minutes to take the Retest. If you are in heavy trafc or on a
dangerous section of road, wait to take the test until you can safely follow correct testing
procedures. For safety reasons and certain road laws, you may choose to pull over
at the Retest prompt, and park the vehicle off the road (away from trafc in a safe position).
Leave the motor running during the Retest.

User Manual • October 2004 Page 10
DRAEGER INTERLOCK® XT
What happens if I fail the Retest?
• Don’t panic! Make sure your mouth and vehicle are free of alcohol vapors and smoke.
• If the alcohol level was low, the device will automatically start another Retest.
When you see "Retest Required - PLEASE BLOW" and the yellow light is ashing, take the
breath test as before.
• If the alcohol level was high, the device may go into the "TEMPORARY LOCKOUT" mode.
If you see "TEMPORARY LOCKOUT", you must pull over and turn the engine off.
Wait for the "TEMPORARY LOCKOUT" timer to count down, then take the breath test again.
SERVICE REQUIRED
The Interlock:
• Must be serviced periodically. (See inside back cover to see how often you need to bring
the vehicle back to the service location so that the Interlock can be serviced).
• Will remind you of an upcoming service appointment after you switch the ignition key
to the “ON” position.
• Will display "Service Required in XX day(s)" a few days before your next appointment.
You will see it each time you switch the ignition key to the “ON” position to begin an
initial test. If you see this message and you have not made an appointment for service,
call your technician to make your appointment.
• Will remind you before it locks out permanently.
• Will display "Service Lockout in 1 day" on the last day before it disables the vehicle for
lack of service.
NOTE:
The message "Service Lockout in 1 day" means that the device will lock out at 12:00 AM (midnight).
You MUST have the device serviced that day or else you will be required to have your
vehicle towed to the service center at your expense.
