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.
