Noise Cancel - Reducing Electrical Interference - Minelab Explorer SE Quick Start Manual

MAIN MENU > OPTIONS > NOISE
56 NOISE CANCEL - Reducing
Electrical Interference
The detector may become noisy
due to electrical interference from
powerlines, electrical equipment or
other detectors operating close by. The
detector interprets this interference as
inconsistent, short beeps, and erratic
movement of the Target Crosshair
on the Smartfind display, or erratic
changing of FER COND numbers in the
Digital display.
The Noise Cancel channel can
be changed so that the detector
experiences the least interference for
the current environment. The channel
can be changed automatically by the
NOISE CANCEL shortcut button, or
manually in the NOISE CANCEL screen
via the menu.
The NOISE CANCEL button instructs
the detector to automatically listen to
every channel and select the quietest
channel. Automatic Noise Cancel may
take up to 30 seconds.
The NOISE CANCEL screen, accessed via
the menu, allows you to manually select
and listen to every channel for the least
interference.
Once a channel is selected, most
audio responses to electromagnetic
disturbances (e.g. powerlines) will be
eliminated.
Range: 1 to 11
Factory Presets: 5
Noise Cancel is handy for metal
detecting competitions when several
Explorer SEs are working close to
one another. Each detector can be
set to operate on a different channel
so interference between detectors is
eliminated. In this case it is best to select
the channels manually.
If you would like to know what channel
has been chosen after an automatic
Noise Cancel, access the NOISE CANCEL
screen and check the channel displayed.
It is best to select a channel with the coil
in the detection position, 30cm away
from the ground and as still as possible.
This gives the detector the best chance
of hearing all surrounding interference
(not from the ground or targets) and
selecting the quietest channel.
It may be useful to switch to Manual
Sensitivity from the Smartfind or
Digital screen before attempting to
perform Noise Cancel.
The number associated with Noise
Cancel does not denote an increase or
decrease in power. It is simply a channel
number which can be remembered.
If you perform an Auto Noise Cancel
while in the NOISE CANCEL screen, you
will have to exit and return to the screen
for the new channel to be displayed.
To automatically select a
Noise Cancel channel:
1 Hold the detector 30cm above the
ground, making sure there are no
large targets or obvious electrical
interferences close by.
2 Press the NOISE CANCEL button.
Keep the detector completely
still during the automatic channel
selection. This may take up to 30
seconds.
The detector will select the quietest
operating channel.
To manually select a
Noise Cancel channel:
1 Hold the detector 30cm above the
ground, making sure there are no
large targets or obvious electrical
interferences close by.
2 Access the NOISE CANCEL screen via
the menu.
3 Use the shift buttons next to the
adjustment arrows to select a channel
listening for interference (or 'noise').
Adjust the detector to a new channel
and listen again. Listen to each
channel and select the one with the
least amount of noise.
