Sample-Free Restart Process:
When the vehicle is shut off after being started, a sample-free restart shall be allowed for 3 minutes by default.
If the device is shutdown when it is awaiting a rolling retest, the sample-free restart shall not be allowed. In
this case, the device would continue the rolling retest process if the vehicle is restarted within the time specified
for the stall time. If the vehicle is started after the specified time, the device will proceed to the initial testing
process.
Mouthpiece:
The mouthpiece is designed to be a moisture trap. It may be washed and reused. Insure mouthpiece is dry before
inserting back into interlock. Mouthpieces that are worn can be replaced by your service center.
Do not use alcohol to clean the mouthpiece. Any alcohol in the mouthpiece will cause a very high reading when
taking a test.
Blood Alcohol Content:
The ignition interlock measures the intended driver’s blood alcohol content. If the driver’s blood alcohol
content is greater than the preset limit, the interlock will not allow the vehicle to start.
Alcohol in the blood takes time to burn off (metabolize). The rate at which alcohol is metabolized is
the same for virtually everyone regardless of their height, weight, sex, race or other such characteristics.
Alcohol is metabolized at the rate of .015 of blood alcohol concentration (BAC) every hour. 1Thus a
person with a very high BAC of .15 will have no measurable alcohol in the bloodstream after ten hours
(.15 divided by .015 = 10). Here are some other examples:
Time Needed for Testing
Completing the test generally takes a few seconds. However, it may take longer for the display to show
startthe test. This increased time may be the resultof:
Alcohol still present from a previous test
The results of the test are immediately shown on the display and recorded in the device’s memory for later use in
performance monitoring. Any attempt to bypass the system isrecorded.
Alcohol in the mouth from any product such as mouthwash, cough medicine, flavoring, etc., may also be indicated
on the system. CAUTION: Normal use of these products may show a blood alcohol content; use extreme
care when using these products. An immediate blow after using these products could result in a failed test.
