Metal Detector VMH3CS – Operation Manual

The lighting diode on the LED-display is shifted either to the left or to the

right according to the mineral concentration of the present soil.

7. Stop pressing button „C“: You will hear one short tone (beep) which

confirms the storage of the achieved data.

3.3.3 Important Notes

NOTE

Start soil compensation only after the detector has adapted itself to the

ambient temperature. In case of more than 15°C difference in temperature

between storeroom and detection place wait for approx. 10 minutes.

NOTE

If the audio signal does not become smaller during the up-and-down-

movement of the search, please check whether a metal object has been

detected.

NOTE

When pressing, by mistake, button “C” during detection longer than approx.

3 seconds, the ground balance will change to another soil condition. You must

repeat the procedure.

NOTE

The program “mineral” adapts the detector to the metallic properties of the

soil. Mines containing metal components with the same electromagnetic

features may be overlooked.

Use program „mineral“ only if absolutely necessary.

Recommendation:

Create a test field in the soil to be detected. This field should contain all mines

to be expected.
