Threshold
This control adjusts the audio tone volume of the background noise, commonly called
‘threshold’. To adjust this to optimum, the sound should be barely audible. When using
headphones, the control will be set lower than when using the speaker. It may be necessary when
using the speaker where the environment is noisy to use a higher setting. Generally, the lower the
setting, the deeper the detection.
Signal Balance
This control adjusts the Signal Balance or detection depth of the detector. The best position is in
the NORMAL range of the control for most searching conditions. This will provide more than
adequate depth with the most stability. If ground or interfering radio/electrical signals cause
erratic behaviour (extreme fluctuations of the threshold tone) the SIGNAL BALANCE control
should be set towards the MIN setting. If greater depths are required, the SIGNAL BALANCE
control may be advanced further clockwise. Caution should be exercised when increasing beyond
the NORMAL range. If the detector operates erratically because of higher setting, the response of
deeper targets may be missed. The NORMAL range offers the optimum setting which will give
smooth operation allowing deep targets to be heard clearly.
