Threshold
Threshold ranges from -9 up to 0. All positive target response signals are audible. When using a negative
threshold, the value is subtracted from the target signal. A Threshold of zero does not affect the signal. To
increase the ability to hear faint signals, it is recommended to set the TrH to -1 or 0. If the detector becomes too
noisy, and quiet work is desirable, a more negative threshold may be used to reduce detector chatter.
