Power Switch
The Power switch controls the power supply from the battery to the control box. Always switch the control box “Off” before connecting or disconnecting the coil or battery, and when not in use.
Threshold
The Threshold control is used to adjust the loudness of background sound. Minelab recommends a soft audible headphone signal that is comfortable to listen to for extended periods.
Tone
The Tone control can be adjusted to suit an individual’s hearing by changing the pitch of the background threshold tone.
Tune
The Tune control is used to lower the effects of electromagnetic interference from sources such as power lines, radio transmitters and other metal detectors.
