What corrective action is needed if "Inhibited RFI" is displayed?

When "Inhibited RFI" is displayed on the Intoxilyzer 8000, it indicates that radio frequency interference (RFI) is affecting the device's ability to obtain an accurate reading. This interference can come from various electronic devices, such as walkie talkies, radios, or cell phones.

To resolve this issue, it is essential to minimize or eliminate any sources of RFI in the vicinity. By turning off or removing these devices from the room, you can significantly reduce the electromagnetic interference and allow the Intoxilyzer to function properly. This ensures the integrity of the test results and maintains the reliability of the data collected by the device.

Other options like restarting the device or waiting for a cooldown period do not address the root cause of the interference, which is the RFI itself. Checking the breath sample is also not relevant in this context as the issue lies with the device's environment rather than the sample being tested.
