If the Intoxilyzer 9000 shows a residual error, how should an operator proceed?

When the Intoxilyzer 9000 displays a residual error, the operator should follow the troubleshooting guide. This guide is designed specifically to assist in resolving errors such as this one by providing step-by-step instructions on how to identify the source of the problem and rectify it.

Following the troubleshooting guide ensures that the operator addresses the issue systematically and thoroughly, reducing the risk of incorrect readings that could arise from skipping steps or attempting to resolve the error without proper guidance. Using the troubleshooting guide can help determine whether it's a temporary glitch or a sign of a more significant issue that requires maintenance or calibration of the device.

Continuing testing as normal or attempting to clear the error and retry could compromise the integrity of the testing process and lead to unreliable results. Seeking technical assistance immediately, while sometimes necessary, may not be the first course of action, especially since operators are trained to address many common issues themselves before escalating the problem.
