Operating Instructions

SWITCHING ON

Before switching the multi-detector on, make sure that the sensor area 9 is not moist. If required, wipe the multi-detector dry using a cloth.

The multi-detector detects objects that are below the sensor area 9.

If the multi-detector was subject to an extreme temperature change, allow it to adjust to the ambient temperature before switching on.

To switch the multi-detector on, press any button.

When switching the multi-detector on with the wood detection mode button 5 or with the metal-detection mode button 6, it will automatically be in the respective detection mode. After a brief self-check, the multi- detector is ready for operation.

When switching the multi-detector on with the “on/off” button 7 or with the “ZOOM” button 4, it will be in the detection mode last used. After a brief self-check, the multi- detector is ready for operation.

When the multi-detector is in the metal- detection mode, the service readiness is indicated through a check mark behind the “AutoCal” calibration indicator g.

RECOMMENDATIONS FOR

PROPER SCANNING

Avoid wearing jewelry such as rings or watches when using the detector. The metal may cause inaccurate detection.

Move the multi-detector uniformly the surface without lifting it off or changing the applied pressure.

During the scan, all three of felt pads 8 must always have contact with the surface.

Make sure that your fingers of the hand holding the multi-detector do not touch the surface being scanned, which could interfere with the tool’s ability to effectively detect items below the surface.

Do not touch the surface being scanned with your other hand or any other part of part of your body, because the moisture may affect the scanning.

Always measure SLOWLY to achieve maximum sensitivity.

MARKING OBJECTS

Detected objects can be marked as required. For this, remove the pencil 11 from the multi- detector and carry out the scan as usual. Once you have found the limits or the center of an object, simply mark the sought after location through the marking opening 2. It is a good idea to establish a consistent practice of making one type of mark over places in which you do not want to penetrate (drill, nail, cut), such as O, and a different symbol over places in which you do want to penetrate, such as an X.

SWITCHING OFF

To switch the multi-detector off, press the “on/off” button 7.

If none of the multi-detector buttons are pressed for approx. 5 minutes, the multi- detector switches off automatically in order to extend the service life of the battery.

SWITCHING OFF THE SIGNAL TONE

The signal tone can be switched on and off. For this, press the metal-detection mode button 6 and the wood-detection mode button 5 at the same time. When the signal tone is switched off, the switched-off audio signal indicator j appears on the display. The signal tone setting is maintained after switching the multi-detector off and on again.
