6 Random Retest
6.1 What is a Random Retest?
To make sure the user stays 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.
 When the Interlock prompts for Retest you will hear a beep
and the yellow light will flash.
 The Interlock display will read “Retest required - PLEASE
BLOW”.
 You will have several minutes to give the test.
 Do not turn off the vehicle to avoid the retest. This will be
recorded as a violation.
The breath sample is given in the same way as the original
test.
6.2 Questions about Random Retests
What happens if I do not hear the retest prompt?
The Interlock XT will start beeping an audible tone
con
tinuously to alert you. Stop the tone by pushing the OK
button and taking the test.
What happens if I do not take the retest in time?
The message “Retest Violation” appears on the display, the
tone
will beep continuously, and the vehicle’s horn may honk
and/or the parking lights may flash. You must turn off the
vehicle to deactivate the horn and lights. The vehicle will not
shut down while you are driving.
What happens if I fail the retest?
Make sure your mouth and vehicle are free of alcohol vapors
an
d smoke. If the alcohol level was above the set-point the
device may go into the Temporary Lockout mode. If this
happens pull over and turn off the engine. Wait for the time to
count down and when prompted to do so, provide a breath
sample.
