There is no loss in depth or sensitivity if
the noise cancel channel is changed.
The detector may become noisy or erratic
due to electrical interference from powerlines,
electrical equipment or other detectors
operating close by. This interference is
interpreted as a crackling or popping noise.
Noise Cancel
* allows you to change the noise
cancel channel so that you experience less
interference. Three channels are available,
represented by the numbers -1, 0 and 1 and
are also indicated on the menu scale.
It is best to choose a channel with the coil
in the detection (horizontal) position because
interference received in a vertical position may
be different from the interference received
in the horizontal position.
The coil should be held in the air and away
from large targets when changing channels.
Noise cancel channels = -1, 0, 1
Factory preset noise cancel channel = 0
