button to reduce electrical interference. The tuning
process takes approximately 60 seconds. Do not move the
coil or pass metal objects near the coil during the tuning
process.

Whilst lowering and raising the coil between 25mm and
100mm (1" and 4") from the ground, change the Ground
Balance switch to Tracking. Any variations in the Threshold
will smooth out within 3-5 seconds.
(pg. 40)
Adjust the Threshold to a very faint but still audible level.
It should be smooth with only minor fluctuations.
