The measuring tool may not be 100% accurate for technological
reasons. For this reason and to eliminate hazards, familiarise
yourself with the area using other sources of information, such as
building plans and photographs taken during construction, etc.
before carrying out any drilling, sawing or milling work on walls,
ceilings or floors. The accuracy of the measuring tool may be affected
by environmental influences, such the level of humidity or there being
otherelectronicdevicesnearby. The structure and conditionofthewalls
(e.g. damp, building materials containing metal, electrically conductive
wallpaper, insulating materials, tiles) and the number, type, size and po-
sition of the objects may distort the measurement results. Inaccurate
readings may be caused, for example, by the building materials (espe-
cially plaster and tiles) being made damp through high humidity.
These influences may result in the indicator LED lighting up green de-
spite there being an object within range of the sensor, or in the indica-
tor LED lighting up red despite there not being an object within range
of the sensor.
Make sure that you are properly earthed when taking measure-
ments. If you are not properly earthed (e.g. by wearing insulating foot-
wear or by standing on a ladder), it will not be possible to locate live
cables.

Operation
Initial Operation
Protect the measuring tool against moisture and direct sun light.
Do not subject the measuring tool to extreme temperatures or var-
iations in temperature. As an example, do not leave it in vehicles for
a long time. In case of large variations in temperature, allow the meas-
uring tool to adjust to the ambient temperature before putting it into
operation. In case of extreme temperatures or variations in tempera-
ture, the accuracy of the measuring tool can be impaired.
Avoid heavy impact to or falling down of the measuring tool.
Switching On and Off
Before switching the measuring tool on, make sure that the sensor
area 7 is notmoist. Ifrequired,drythemeasuringtool using a softcloth.
To switch on the measuring tool, slide the On/Off switch 3
downwards.
Afterashort self-test, the tool isreadyfor use. The readiness ofuseis indi-
cated when the signal LED 2illuminates. If the signal LED 2fails to illumi-
nate after switching on the tool, you must replace the batteries.
To switch off the measuring tool, slide the On/Off switch 3
upwards.
When no measurements are carried out for approx. 10 minutes, the
measuring tool switches off automatically in order to extend the service
life of the batteries.
Note: The on/off switch 3will remain in the “on” position when the
measuring tool switches itself off automatically. To switch the measuring
tool back on, switch it off first before switching it on again.

Operating Modes
The measuring tool detects objects below the sensor area 7.
Detecting Metal Objects
After switching on, the signal LED 2lights up green.
Position the measuring tool on/against the surface being detected and
move it sideways.
– If no metal object is visible in the base material, then the signal LED 2
continues to illuminate green and no signal tone sounds.
– When the measuring tool comes closer to a metal object, the signal LED
2firstlightsupyellowandchangestored the closer it comestothemetal
object. As soon as the signal LED lights up red, a signal tone is also emit-
ted, the pitch of which rises the closer it comes to the metal object.
– Over a metal object, the signal LED 2illuminates red and a signal tone
is emitted at maximum pitch.
Even with a yellow signal LED 2, a metal object may be located be-
low the sensor area. Small or low-lying metal objects are located in
the vicinity of the sensor or the wall material impairs the measurement
results.
Signal LED Explanation
green no object detected
yellow – metal object in the vicinity of the sensor
– small or low-lying metal object within
the sensor area or
– impairment of the sensor due to unfa-
vourable wall material
red and continuous tone metal object detected in the sensor area
red flashing (fast) and
intermittent sound “live” wire/conductor detected

Bosch Power Tools 1 609 92A 3FC | (4.8.16)
After moving over the surface the first time, the posi-
tionof the metal object is only roughly indicated. If you
move the measuring tool over the metal object several
times, the object detection will become increasingly
precise. After moving over the metal object several
times (without lifting the measuring tool from the base
material), its position can be indicated very accu-
rately: if the signal LED 2illuminates red and the signal
tone sounds, the metal object is below the sensor area. When the pitch of
the signal tone is highest, the metal object is located below the centre of
the sensor.
Scanning for “Live” Wires
The measuring tool indicates wires, which carry voltage between 110 V
and 240 V and a frequency corresponding to the widely used standard
(AC with 50 or 60 Hz). Other wires (carrying DC, higher/lower frequency
or voltage) as well as non-“live” wires/conductors cannot be found relia-
bly, but are possibly indicated as metal objects.
The detection for “live” wires/conductors takes place automatically with
every measurement. When a “live” wire/conductor is detected, the signal
LED 2flashes red and an intermittent signal tone sounds with rapid tone
sequence. Move the measuring tool repeatedly over the surface to locate
the “live” wire/conductor more precisely. After moving over the surface
several times, the position of the “live” wire/conductor can be indicated
very accurately.
Itiseasiertofindlivecables if electricity consumers(e.g.lights,appliances)
are connected to the cable being searched for and are switched on. Switch
off electricity consumers before drilling, sawing or milling into the wall.
Note: Always ensure that you hold the measuring tool firmly without
gloves to enable a good grounding. Also ensure that ladders/scaffolding
must be grounded. Avoid ladders/scaffolding whose supports have plas-
tic caps underneath them. Do not wear insulating footwear.
It may not be possible to find live cables in certain conditions (e.g. behind
metal surfaces, behind surfaces that are very dry or very damp). If the in-
dicator LED 2lights up yellow or red over a large area, the material is elec-
trically shielded and you will not be able to find live cables accurately.

Working Advice
To avoid affecting the measurement, do not hold the measuring tool within
range of the sensor. This will enable you to obtain more accurate measure-
ment results.
Marking Objects
Detectedobjectscanbe marked as required. Theouteredgesofanobject
are indicated by the colour change of the signal LED 2from yellow to red.
The centre of the metal object can be determined by the pitch. Using a
pen, mark the sought after location at the top and the side marker aids 1.
Continuous Flashing Green/Yellow/Red
Ifthe signal LED 2flashesalternately green, yellow and red,even when no
metal object or no “live” cable is in the vicinity, the measuring devicemust
be sent in for service.
Maintenance and Service
Manual Calibration
If the signal LED 2illuminates red or yellow, even when no metal is in the
vicinity of the measuring tool, the tool must be recalibrated.
– To do this, switch the measuring device on using the On/Off switch 3.
– Remove a battery from the switched on measuring device.
– While the battery is removed, switch the measuring device off using
the On/Off switch 3.
– Reinsert the batteries into the measuring device (pay attention to the
polarity!).
– Now remove all objects in the vicinity of the measuring device (includ-
ing wrist watches or rings of metal) and hold the measuring tool up in
the air.
– SwitchthemeasuringdeviceonusingtheOn/Offswitch 3and off again
within 3 seconds. The signal LED 2of the measuring device will flash
red in slow succession during the 3 seconds to indicate that it is ready
to calibrate.
– Switch the measuring device back on within 0.5 seconds. The calibra-
tion is initiated and takes about 6 seconds. The signal LED 2will flash
green for 6 seconds in quick succession, the calibration is being per-
formed. Now the device is once more ready for operation and the
signal LED 2illuminates solid green.
