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 for
the 305, represented by the numbers –1, 0
and 1 and are also indicated on the menu
scale. Five channels are available for the 505,
represented by the numbers –2, –1, 0, 1 and 2.
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.
