Reattempt to do a breath test and wait a little while longer for the unit to warm up. If this failure persists, contact Bedfont or a distributor for support.

Try pressing the retry button. If the error occurs more than 3 times, please restart the unit. If failure persists then please contact [your local distributor](https://www.bedfont.com/find-my-distributor/) for support.

This could also be an issue that occurs when there is a loose connection to the bench/PCB. Contact [your local distributor](https://www.bedfont.com/find-my-distributor/) for support.
