Noise Cancel
Detectors can become noisy due to electrical
interference from power lines, electrical
equipment or other detectors operating nearby�
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� It has a default setting of 0 [zero] for all Search
Mode Profiles�
Noise Cancel adjustment is local; only the current Search
Mode Search Profile is affected by changes to this setting�
Noise Cancel should be carried out whenever the
frequency setting is changed�
CONTENTS
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�
3. Press either the Accept/Reject button or the Minus (–) or
Plus (+) button to initiate the Auto Noise Cancel�
4. The Auto Noise Cancel progress is indicated on the
Discrimination Scale, and by a series of ascending tones�
When this process is complete (after approximately
8 seconds), the automatically selected channel
appears on the Target ID Display, and there are three
confirmation tones�
Note: While Auto Noise Cancel selects the
'quietest' channel based on several criteria, the
selected channel may still have some audible noise�
To try and reduce noise further, consider adjusting
Sensitivity�
