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.
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.
