Noise Cancel

Minimizing electrical interference.
Noise Cancel is a function which
reduces the effects of some types
of electrical interference, such as
power lines, or other nearby
metal detectors. During Noise Cancel, the
detector automatically searches for and selects
the quietest operating channel.
If the detector is noisy when held stationary,
use Noise Cancel to reduce interference.
To operate Noise Cancel, follow the steps
below:
1. Hold the coil stationary and away from the
ground.
2. Press and release the Noise Cancel button.
3. Wait for the Noise Cancel process to finish.
4. Commence detecting.
The Noise Cancel process will take
approximately 50 seconds to complete.
A series of beeps will be emitted during
the process, followed by 4 single beeps at
completion.
Threshold
Adjusting the background audio level.
Threshold is the constant audible
background tone produced by
the detector. When a target is
detected the threshold changes
in both volume and pitch. The Threshold level
could be considered an audio reference point.
Small targets or large deep targets may not
produce a distinct target signal, but may cause
only a small variation in the Threshold.
Therefore it is important to set the Threshold
so it can be heard. If the Threshold level is set
too high or too low, these small variations may
not be heard.
There are nine Threshold levels available on
your SDC 2300. Each press of the Threshold
button will increase the Threshold by one
setting as indicated by the LEDs. If the
Threshold is already at the maximum setting,
then pressing the button will cycle back to the
quietest setting.
