Which of the following is NOT a feature of the Intoxilyzer 9000?

The Intoxilyzer 9000 is designed with several advanced features to enhance its functionality and reliability in alcohol testing. One notable feature is automated testing, which allows the device to perform the testing process with minimal manual input from the operator, increasing efficiency and reducing the likelihood of human error. The built-in printer is another important feature that enables immediate printing of results after the test is completed, providing a tangible record for law enforcement and legal purposes. Additionally, tamper resistance is a critical aspect of the device, as it ensures the integrity of the test results by preventing unauthorized modifications or tampering with the instrument.

In contrast, mouthpiece recycling is not a feature of the Intoxilyzer 9000. This device is designed for single-use mouthpieces to ensure hygienic and accurate testing practices. Using single-use mouthpieces helps eliminate the risk of contamination and cross-sampling, thereby maintaining the reliability of the results. Hence, mouthpiece recycling does not align with the operational focus of the Intoxilyzer 9000, making it the correct choice for this question. Understanding these features is crucial for ensuring proper operation and adherence to protocols during alcohol testing.
