Sometimes during detecting you may notice some interference in

the form of erratic noises and movements of the target crosshair

(even without movement of the detector). The NOISE option

enables you to select an operating channel which does not clash

with other detectors or electrical sources in the area. This feature

is also good for metal detecting competitions if several Explorer

IIs are working close to one another. Each detector can be set to

operate on a different channel so interference between detectors

is eliminated.

The factory setting for NOISE is 5.

NOTE It may be useful to select manual sensitivity from the

Smartfind or Digital screen before attempting this procedure.

Sensitivity is covered in Chapter 5: Quickstart, page 49.

To adjust channel for least noise:

STEP 1 Rest detector on the ground. Make sure the detector is not

moved and the area is clear of targets.

STEP 2 Use the shift buttons next to the adjust arrows to select a

channel and listen for interference (or ‘noise’). Adjust the

detector to a new channel and listen again. Do this with

each channel in turn until you locate the channel with the

least noise.

NOTE The number associated with Noise does not denote an

increase or decrease in power. It is simply a channel number

which can be remembered.
