HNote:

If the reference echo symbol does not appear, no refer- ence echo was recorded. Possible reasons are:

•The reference echo is outside of the monitor gate.

•The amplitude of the refernce echo is either too low or too high.

Correct the settings correspondingly and record the reference echo again.
