Auto Noise Cancel; Auto Noise Cancel Procedure - Minelab MANTICORE Instruction Manual

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 or 'noise'�
The Noise Cancel setting allows you to change the noise
cancel channel� This slightly shifts the detector transmit
frequency to be less responsive to sources of 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 Modes�
Noise Cancel adjustment is local; only the current Search
Mode is affected by changes to this setting�
Auto is the recommended Noise Cancel method�
Perform a Noise Cancel each time the Frequency
setting or Seach Mode is changed�
You can assign Noise Cancel as a Soft Key Action
— see page 35�
