Instruction manual
Noise Cancel Channel
11
When I am condent the batteries are sucient to maintain operation, I set the
Noise Cancel Channel. Some X-TERRA models do this manually and others do it
automatically. Refer to your Instruction Manual to learn how this is best accomplished
with your particular detector. If your X-TERRA oers Auto Noise Cancel, use it! The
Auto modes oered by some models of X-TERRA are far more accurate at obtaining
proper operating levels than we are able to accomplish.
Regardless of which model you have, while setting the Noise Cancel Channel, make
sure you hold the coil away from any large metal objects. And, hold it in a horizontal
position as you would while detecting.
Remember, the coil of your detector acts as an antenna for more than just the target
signals. Setting the proper Noise Cancel Channel will minimize the interference you
might receive from electrical equipment, power lines or other metal detectors.
Did you know that the Noise Cancel
adjustment shifts the transmit
frequency by 40 Hz steps for the
7.5 kHz coils?
Here’s an example of how the
frequency changes for the dierent
Noise Cancel Channels for a 7.5 kHz
coil on the X-TERRA 705.
