Powering ON or OFF
Press the power button momentarily to turn the detector ON, with the search coil away from the ground surface and any metal objects. The display shows all segments briefly and after three different audio tones the detector defaults to DISC mode and shows the last used discrimination pattern. For initial use, the detector starts with the discrimination pattern that accepts all target categories. To turn the detector OFF, press and hold the power button until the display goes blank.
Adjusting the Sensitivity
In DISC mode, press the SENS(+) button to increase the sensitivity level or the SENS(-) button to decrease. The sensitivity indicator bars will show the current sensitivity setting. There are 8 steps of sensitivity level. The more bars displayed, the higher the sensitivity level.
If the sensitivity is set too high, excessive noise will make it difficult to locate targets due to the noise from either the ground or external electric interference. Too-high sensitivity is noted by false signals. Lowering the sensitivity will improve performance. Increase sensitivity for increased depth when the ground and external conditions allow.
Adjusting the Volume
The detector provides eight volume levels. In DISC mode, press the VOL(+) button to increase the volume level or the VOL(-) button to decrease based on your preference and environmental conditions. The volume icon and the volume indicator bars will be displayed briefly to show the current volume level. The number of indicator bars is proportional to the volume level.
Turning the Backlight ON or OFF
The detector has a backlit display option for use in low-light conditions. Backlight use will reduce battery life but may be necessary in some conditions. During use, you can press the settings button to turn the backlight ON or OFF.
Customizing the Discrimination
The detector features a Discrimination Setting mode, allowing you to create a personalized discrimination pattern. In this mode, you can set the detector to accept or reject specific target categories. If a target category is set to be rejected, targets within this range will not produce any tone when detected.
To customize a discrimination pattern:
1. Press the settings button to enter Discrimination Setting mode. A flashing selection cursor will appear on the display.
2. Use the VOL(+) and VOL(-) buttons to select a target ID icon you want to modify. The VOL(+) button moves the selection cursor to the right, and the VOL(-) button moves it to the left.
3. Press the 
button to toggle between accepting and rejecting the selected target category. A visible target ID icon frame means the category is accepted; a hidden frame means it is rejected.
4. Press the settings button again to exit Discrimination Setting mode and save your settings. The following shows an example of discrimination setting, and it tells us that:
·The fork, iron, 10¢ and quarter categories will not produce any tone when detected.
·All other target categories will produce a tone when detected.
