Inserting/replacing batteries
Open the lid of the battery compartment (12) at the back. Insert a 9 V block battery (not included
in the delivery) with the correct polarity into the battery compartment (observe plus / + and
minus / -), close the battery compartment.
Change the batteries if the battery status indicator (A) no longer shows a dash or the display
contrast is very low. When the batteries are completely empty, only the edge of the battery
status indicator (A) flashes and the detector will automatically switch off.
On/off switch
Grab the detector on the left and right sides of the housing. Hold it in the air in front of you so
that the round sensor area (11) is exposed.
Press the button "5" briefly to switch on the detector. The detector will emit a short beep, the
display will appear, and the backlight will turn on. The green LED (3) will shine.
When switching on the detection mode
You can then select one of the functions or start measuring, see the following chapters.
Briefly press the button "5" to switch off the detector.
If no button is pressed, the detector switches off automatically after a few minutes to
save power.
Switching the tone signal on/off
During the detection process and while operating the buttons, a beep serves as additional
control. This beep can be switched off.
To turn the beep on or off, press buttons (6) and (8) simultaneously for approx. 2 seconds.
If the detector is switched off and then switched on again, the beep is automatically
reactivated for safety reasons.
Select detection mode
"Metal" detection mode
This mode is preset automatically after switching on.
If the detector is in a different detection mode, briefly press the button (8) once, until the
symbol
(C) appears on the display.
Detection mode "AC voltage"
Press the button (8) twice, until the symbol (B) appears in the display.
Detection mode "Wood"
Briefly press the button (6), until the symbol

Performing the detection
a) General
Keep in mind that the device cannot guarantee 100% detection of hidden compo-
nents or power cables. The results of the device should therefore only be used as
additional information!
To avoid danger as far as possible, before any drilling/screwdriving or other masonry
work be sure to consult other sources of information such as construction plans,
photos from the construction phase, etc.
Proper detection can be hindered by various influences. Masonry, moisture in the
wall (or in wooden beams), metallic building materials, metal foils on insulation ma-
terials or similar can have a significant influence on the detection process.
When trying to detect power lines (AC voltage), it is necessary that the power is
turned on. If the lines are de-energised, the detector would only react to the metal in
the lines, resulting in much lower detection performance.
Damping material between wooden beams (e.g., in prefabricated houses) may
make the detection of wooden beams more difficult or even impossible depending
on their condition.
Before making measurements with the detector, remove rings as well as any watch
or bracelet from your hand. Metal parts in the vicinity of the detector influence the
measuring process and cause faulty signals.
Only hold the detector by the left and right sides during calibration and measurement
(as far down as possible, away from the sensor or buttons), otherwise the measure-
ment will impair the reading.
The detector has a special manual calibration function and a signal strength display using a
bar graph (I) and% value (K).
Using the manual calibration function, a given reference value (actual state) can be used as
the basis for further measurements and their display. By repeated calibration during a detection
process, even small changes in the wall can be detected!
The bar graph gives a good estimate of the location of metal parts, wooden beams or power
lines in the wall.
b) Performing the first calibration
K
The detector performs the first calibration directly after turning on (automatic measuring mode)
or when another measuring mode is selected. This means that if you hold the detector in front
of you and you switch it on (or you choose a different detection mode), then the "empty" space
is stored as a reference value. The green LED (3) shines.
For example, if you place the locating device on a wooden board and then select the detection
mode "wood", the measuring signal of the surface is saved as a new reference value.
If you want to find a metal pipe or a mains power line, place the locating device in a spot on
the wall where definitely no metal pipe and no power line is located. Then select the detection
mode "metal" or "AC voltage". The detector now takes the wall as a new reference value.
c) Performing detection process
When searching for a wooden beam, a metal pipe or a mains voltage power line, the detector
compares the reference value (see above, section b) with the current measured value. Devia-
tions are then displayed by bar graph, signal strength value, LEDs and a beep.
Hold the detector vertically or horizontally.
Move the detector along the wall.
Notches on all 4 sides of the detector will
indicate the centre of the sensor area (11)
(dashes in the image on the right).
In addition, you can make marks on the
wall in the notches using a pen, if some-
thing was found.
The more bars appear in the bar graph and
the higher the signal strength, the stronger
the signal, and the more likely it is to find a
wooden beam, metal tube, or power line (depending on the location mode selected).
In addition, 3 LEDs and a beep are used as an additional display during the detection process:
• Green LED (3) shines = no detection or reference value, no sound signal
• Yellow LED (2) shines = slight deviation from the reference value; wooden beam/metal pipe/
power line nearby (depending on the selected locating mode); continuous beep audible
• Red LED (1) shines = strong deviation from the reference value; wooden beam/metal pipe/
power line nearby (depending on the selected locating mode); continuous beep audible, as
well as a cross-hair pointer
If the red LED (1) flashes and the detector beeps (instead of a continuous tone), very
large deviations from the reference value have been detected (overridden). Perform
a recalibration.
In detection mode "metal", the depth of the object in the wall is displayed (F). The
symbol
appears for non-ferrous metals (e.g., aluminium).
