34NOISE CANCEL

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. Five channels are available, represented by the numbers -2, -1, 0, 1, 2, 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 Noise Cancel channels.

There is no loss in depth or Sensitivity if the Noise Cancel channel is changed.
