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.

DRAEGER INTERLOCK® XT
USING THE INTERLOCK
Turning on the System:
• Put out your cigarette (if applicable) and remove chewing tobacco, candy, gum, or any other
food product from your mouth.
• Always use a clean, dry mouthpiece.
• Make sure the mouthpiece is inserted properly as shown in Figure 1.
• Insert key into the ignition switch.
• Turn key to the “ON” position (usually two clicks).
Turn key back to the “OFF” position.
The Interlock will display "Warming Up - PLEASE WAIT" on the screen as shown in
Figure 2.
• When the Interlock is ready for the BAC test, it will display "Ready for Test - PLEASE BLOW"
on the screen as also shown in Figure 2 and the yellow light will ash.

DRAEGER INTERLOCK® XT
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.

User Manual • October 2004 Page 7
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.

DRAEGER INTERLOCK® XT
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.

User Manual • October 2004 Page 11
DRAEGER INTERLOCK® XT
SERVICE REQUIRED
You must take your car to the Service location:
• When Service is required.
• When the device displays "Service Lockout".
The Service Provider will collect the stored information and:
• Log the odometer reading.
• Inspect the Interlock for evidence of tampering.
• Check the wiring and connections.
• Calibrate the Interlock at the State- or Manufacturer-specied interval.
• Schedule your next appointment.
VIOLATION RESET
The Interlock is programmed to require servicing earlier than usual if it detects violations.
"VIOLATION RESET" might be caused by:
• A failed Breath Alcohol Test.
• A skipped Retest.
• A failed Retest.
• Tampering with the Interlock.
• Trying to circumvent the Interlock.
If you see "Service Lockout in XX day(s)", and you know that you are more than about a
week from your next appointment, you should contact your Service Provider and make an
appointment for service.
IMPORTANT
The device will lock out permanently if not serviced when required and you will not be able
to start your vehicle.

User Manual • October 2004 Page 12
DRAEGER INTERLOCK® XT
LOCKOUT RESULTING FROM MISSED SERVICE
What happens if the Interlock locks out from lack of service?
• If you do not get the device serviced, it will go into permanent lockout.
When you try to start your vehicle, you will see "Service Lockout" (Figure 7).
If the device is in permanent lockout, you must:
• Tow the vehicle to the Draeger-authorized service
location of your choice at your expense.
PROPER INTERLOCK CARE
Keep it dry
• Like a radio or cellular phone, the Interlock cannot work properly when it is wet.
• Keep the Interlock on the Hook and Loop Tape attached to you car interior console.
• Make sure your windows are always closed when you are away from your vehicle.
• DO NOT spill anything onto or into the Interlock.
If you spill something onto or into the Interlock, contact your service technician immediately.
DO NOT turn the key to the “ON” position to start a breath test.
NOTE:
You must pay the costs to replace or repair the Interlock if it gets wet.

Exterior Care
• Use a lightly dampened cloth to wipe off dirt if the outside of the Handset becomes dirty.
• Never use a cleaner or soap on the Handset.
• For a very soiled or dirty Handset, request that the service technician clean it for you at
your next Service appointment.
Misuse, Abuse and/or Neglect
• Take care of the Interlock while it is in your possession.
• Treat the Interlock as you would a cellular phone or other portable electronic device.
• Always place the Handset on the Hook and Loop Tape when not in use.
• You will be held liable for damage for which the Service Provider, Service Technician
or Manufacturer believes has been caused by misuse, abuse and/or neglect of the Interlock.
DISCONNECTING THE HANDSET
(Only if and when Pre-approved)
IMPORTANT
With authorization only, you may be instructed to remove the handset only when temperatures
are extreme. The handset must not be disconnected while driving, or while the interlock is
requesting a retest. If the Handset is disconnected at these times, it will result in a Violation.
Extremely cold temperatures can increase the time
for the Interlock device to allow a breath test. To
lessen wait times in extremely cold temperatures,
the handset should be disconnected and taken out
of the car. The Interlock should be placed in a
location where the temperature is roughly room
temperature.
In extremely hot temperatures, the unit may not
start until it is cooler. Therefore, if approved, you
must temporarily remove the handset from the
vehicle and place it in a location where the
temperature is roughly room temperature.
Figure 8
Disconnecting the
Handset
To remove the Handset
from the vehicle, unplug the
modular plug cable that is
located at the bottom of the
handset by pressing down
on the lever and gently
pulling the cord out of the
handset.
