We have an ancient machine and no user manual if any kind. How are we supposed to interpret the SQI squares in the top right corner of the screen? The 4 boxes that are either green, yellow, or red?

SQ squares
Fri May 28 2021Reply from Ray Brown, CBET

The SQI is the Signal Quality Indicator. As copied from the operators manual:
Level 1 (Green) Normal All aspects of the signal are optimal
Level 2 (Green) Intermediate Indicates a moderately compromised signal
Level 3 (Yellow) Poor Indicates poor signal quality
Level 4 (Red) Unacceptable Indicates severe problem with one or more aspects of signal quality.
