The Little Wizard can easily be fine-tuned or adjusted to your environmental conditions. Follow this procedure if your Little Wizard is displaying any of the following problems:
Doesn't Beep
Continuously Beeps
Works Intermittently
Doesn't Detect Metal
Cannot Adjust Working Point

First, make sure you are using a good battery. Battery problems account for the vast majority of problems seen with the Little Wizard.

1. Remove the battery cover and battery.
2. Remove the Cover Retaining Screw, located in the center of the underside of the unit. Use a small phillips head screwdriver (Figure 1).
3. Remove the cover, by lifting slowly from the battery end.
4. Locate the internal Fine Adjustment screw, located near the battery end of the circuit board. It is a round white knob with a cross shaped in the middle (for a phillips head screwdriver). (Figure 2)
5. Attach a good working battery.
6. Support the battery and the unit in one hand, and hold the unit away from any metal.
7. Turn the unit on by rotating the on/off/adjustment dial about half way.
8. If the unit IS beeping, rotate the internal adjustment screw counter-clockwise until the beeping just stops. (Figure 3)
9. If the unit IS NOT beeping, rotate the internal adjustment screw clockwise until the beeping starts, then back off just to where the beeping stops.
10. Test the unit by passing the detector head over a piece of visible metal.
11. Turn the unit off, and disconnect the battery.
12. Replace the cover: Connect the cover to the base at the detector head end first, then close the cover. Tighten the cover retaining screw.
13. Re-connect the battery and replace the battery cover.

The unit is now fine-tuned for your environmental conditions.
