Operation
INSERTING/REPLACING THE BATTERY
Use only 9Vbattery. Insert the battery into the battery compartment (13) in accordance with the symbols in the battery com-
partment. Remove the batteries if the unit will not be used for a long period. The battery can be corroded or discharged over
long periods.
SWITCHING ON AND OFF
Protect the measuring tool against moisture and direct sun irradiation. Before switching the measuring tool on, make sure that
the sensor area 12 is dry. If required, wipe the measuring tool dry using a cloth.
If the measuring tool was subject to an extreme temperature change, allow it to the adjust to the ambient temperature before
switching on. Press ON/OFF button to switch on the instrument. After a short test the detector is ready for operation.
The measuring tool automatically enter the function mode of metal detection.
SCANNING
Put the tool on the surface of the object. Choose the correct operating mode and always move the tool in a straight line
(as shown on the picture).

When the tool is on the surface of the object, the illuminated ring lights up green.
Measuring indicator i indicates maximum amplitude above the center of the object. Illuminated ring (1) lights up red and audio signal
sounds. For small and deeply embeded objects ring (1) can continue to light up yellow while there is no audio signal. To localize the
object more precise, move the measuring toolo repeatedly (3x) back and forth.

DETECTION OF OBJECTS
The detection of metal objects
Press button 9 to detect metal objects. Illuminated ring (1) and indication above the button (4) light up green. Symbol
(the metal detection indicator) or is indicated on the display.
Note: Scale “i” will show all scale for reinforcement steel mesh and steel in the examined base material. Illuminated ring lights
up green.
Place the measuring tool onto the surface to be scanned and move it sidewards, when the measuring tool comes close to a metal
object, the amplitude of the measuring indicator “j” increases. When it moves away from the object, the amplitude decreases,
at the position of maximum amplitude, the metal object is located below the center of the sensor. Indicator k is displayed on the
display.
Indicator “i” (detection depth value) is displayed on the display when scanning metal objects. The accuracy of depth value is a
relation of shape and position of scanning metal objects. Symbol e/d shows whether metal is magnetic or not. Illuminated ring
lights up yellow.
Note: If examined objects are small and deeply embedded, move the detector in horizontal and vertical direction. Pay
attention to the indication “i” and “j” for accurate detection.
Multi-functional wall detector mode
Choose this mode for operation. The detector can indicate following items in the wall (except wooden beam):
- magnetic metal
- non-metal, e.g. beam, plastic pipes that are full of water.
- charged object, e.g. electric wire.
Press button 10. Illuminated ring and indicator above the button light up green. The detector can detect wooden beam as metallic
object when scanning the metallic objects, nails, screws. In that case place the instrument on another place of the examined object
and restart the measuring procedure.

In rear cases the detector can’t detect examined object, because the sensor area and type plate are solid and dirty. Just clean the
measuring tool with dry and soft cloth and restart the measuring procedure.
Scanning for “live” wires
This mode is suitable for detecting “live” conductors (110-230V). Press button 8 to activate Charged wire mode. Illuminated
ring and indicator above button 8 light up green. When a live conductor is detected, indication f appears on the display. Move
the detector above the measuring area several times to detect live wires. When the measuring tool is very close to the conductor,
the illuminated ring ashes red and audio signal beeps swiftly.
Under certain condition (such as below metal surfaces or behind suefaces with high water content) “live” conductors cannot
be securely detected.
Static electricity can lead to inaccurate indication of electric lines, e.g. over a large range. In that case place your free hand at
on the wall next to the measuring tool, in order to remove the static electricity.
Temperature control
The detector is equipped with a temperature control indicator . When the temperature control inducator lights up, the mea-
suring tool is out of the operating temperature range or there are signicant variations oin temperature. Switch the tool off and
allow it to adjust to the ambient temperature before switching it on again.
Operating Instructions
In accordance with the principles of tool operation, the measuring values can be impaired through certain ambient
conditions. These include, e.g. the proximity of other equipment that produce strong magnetic or electromagnetic elds,

moisture, metallic building materials. Foil-laminated insulation materials or conductive wallpaper. Therefore, please also
observe other information sources (e.g. construction plans) before drilling, sawing or routing into walls, ceilings or oors.
Maintenance and service
Wipe away debris or contamination with a dry, soft cloth. Do not use cleaning agents or solvents. In order not to affect
the measuring function, decals/stickers or name plates, especially metal ones, may not be attached in the sensor area on
the front or back side of the measuring tool. Do not remove contact pads (11) on the back side of the measuring tool.
Disposal
Measuring tools, accessories and packaging should be sorted for environmental-friendly recycling.
Only for EC countries:
Do not dispose of measuring tools into household waste! According the European Guideline 2002/96/EC for Waste
Electrical and Electronic Equipment and its implementation into national right, measuring tools that are no longer usable
must be collected separately and disposed of in an environmentally correct manner.
Battery packs/batteries: Do not dispose of battery pack/ batteries into household waste, re or water. Battery packs/
batteries should be collected, recycled or disposed of in an environmental-friendly manner.
Only for EC countries:
Defective or dead out battery packs/batteries must be recycled according the guideline 91/157/EEC.
