Noise Cancel - Minelab EQUINOX 600 Instruction Manual

Contents

Noise Cancel

Noise Cancel reduces the effect of environmental electromagnetic noise from sources
such as power lines, mobile phone towers, and other metal detectors.
Detectors may become noisy due to electrical interference from
power lines, electrical equipment or other detectors operating
close by. The detector interprets this interference as inconsistent,
erratic detections.
The Noise Cancel setting allows you to change the noise cancel
channel. This slightly shifts the detector transmit frequency to be
less responsive to the source of the noise.
Noise Cancel affects both the audible detection noise level and
pinpointing performance.
The Noise Cancel setting has 19 channels with a range from -9 to 9
with a default setting of 0 for all Detect Mode Search Profiles.
Noise Cancel adjustment is local; only the current Detect
Mode Search Profile will be affected by changes to this setting.
Auto is the recommended noise cancel method.
Noise Cancel should be carried out whenever the
frequency setting is changed.
Auto Noise Cancel
Auto Noise Cancel automatically scans and listens to every
frequency channel and then selects the one with the least
interference.
1. Hold the coil stationary and away from the ground.
2. Press the Settings button to navigate to the Noise Cancel
setting in the Settings Menu.
3. Press the Accept/Reject button to initiate the Auto Noise
Cancel process.
Auto Noise Cancel can also be initiated on the EQUINOX 600 by
pressing the Minus (–) or Plus (+) buttons.
4. During the Auto Noise Cancel process the Discrimination Scale
will show the progress of the operation, and there will be a
series of ascending tones (approximately 8 seconds).
When this process is complete, the automatically selected
channel will appear on the Target ID Display and three
confirmation tones will sound.
5. Press either the Detect Mode button or the Pinpoint/Detect
button to return to the Detect Screen.
6. The new Noise Cancel channel will be saved for the current
Search Profile.
Manual Noise Cancel*
The Manual setting allows you to listen to each channel so you can
manually select the one with the least interference.
This can be useful when detecting in close proximity to other
detectors, or in locations with lots of electrical interference.
1. Hold the coil stationary and away from the ground.
2. Press the Settings button to navigate to the Noise Cancel
setting in the Settings Menu.
3. Press the Minus (–) or Plus (+) buttons to change the channel.
The channel is shown on the Target ID Display. Pause and
listen to the interference being received. Keep the detector still
during this process.
4. Once the channel with the least interference has been found,
press either the Detect Mode button or the Pinpoint/Detect
button to return to the Detect Screen.
5. The new Noise Cancel channel will be saved for the current
Search Profile.
The current Noise Cancel channel is shown
on the Target ID Display. Press the Accept/
Reject button to initiate Auto Noise Cancel.
Auto Noise Cancel complete. The
automatically selected channel is shown
on the Target ID Display (e.g. 9)
Noise Cancel | 39
The Target ID Display animates, and the
Discrimination Scale indicates progress.
Auto Noise Cancel
selects the
'quietest' signal
channel based on several
criteria. However,
sometimes this selected
channel may still have
some audible noise
present.
