CH4 Sensor Failure On GastroCH4ECK

Why does my GastroCH4ECK have a red cross next to a pink circle?

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 Bedfont or their distributor for support.

This could also be an issue that occurs when there is a loose connection to the bench/PCB. Contact Bedfont or a distributor for support.

If the problem persists or has not been resolved by the information provided above, please contact Bedfont or your local distributor for more advice.
