How to Troubleshoot RF Air Temperature Warning Detected Error Messages See Long Description The errors shown below is stopping the customer from scanning. This type of error is new for Discovery MR750. We need information on how to approach troubleshooting this type of error. For example, where is the sensor located that is triggering the error? What temperatures would trigger the error? Could facility coolant or ambient air temperature be responsible? What system hardware could be responsible for the error?
