– In certain conditions (such as behind metal surfaces
or behind surfaces with high water content), live
wires cannot always be detected. The signal strength of
a live wire depends on the position of the cable. There-
fore, take further measurements in close proximity or use
other information sources to check if a live wire is
present.
– You can detect non-live wires as metal objects in the
Metal operating mode. Solid-wire cables are not detected
(as opposed to stranded-wire cables).
– Static electricity can cause wires to be detected inaccur-
ately (e.g. over a large area) or prevent them from being
detected at all. To improve the detection, place your free
hand flat on the wall next to the measuring tool, in order
to remove the static electricity.

Working Advice

Marking objects
If required, detected objects can be marked. Perform a
measurement as usual.
Once you have found the boundaries or the centre of an ob-
ject, mark its position through the marking hole (2).
Temperature monitoring
The measuring tool features temperature monitoring, as an
exact measurement is only possible as long as the temperat-
ure inside the measuring tool remains constant.
If the temperature monitoring indicator (f) lights up, the
measuring tool is outside of the operating temperature
range, or has been subjected to large fluctuations in temper-
ature.
Switch the measuring tool off and allow it to adjust to the
ambient temperature switching it back on.
Warning function
If the warning indicator lights up in the display (b), you must
restart the measurement. Remove the measuring tool from
the wall and place it elsewhere on the surface.
If the warning indicator (b) flashes on the display, send the
measuring tool in its protective bag to an authorised Bosch
after-sales service centre.
Recalibration
If the measuring indicator (h) indicates a continuously high
amplitude, even though there is no object near the measur-
ing tool, the measuring tool can be manually recalibrated.
– Ensure that the battery indicator (g) still shows a ca-
pacity of at least 1/3.
– Switch the measuring tool off.
– Remove all objects near the measuring tool that could be
detected (including watches or metal rings).
Hold the measuring tool up horizontally so that the rear
side of the measuring tool is pointing towards the floor.
Avoid bright light sources and prevent direct sunlight
from shining on the rear side of the measuring tool,
without covering this area.
– Switch on the measuring tool. As soon as the measuring
tool starts, immediately press and hold the on/off
Bosch Power Tools
button (4). Do not release the on/off button until the
light-up ring (1) flashes slowly and therefore indicates
calibration of the measuring tool.
– If the calibration was successful, the light-up ring (1)
lights up green and the measuring tool is automatically
ready for operation again.
Note: If the measuring tool does not start automatically, re-
peat the recalibration. If the measuring tool does not start,
send it to an authorised Bosch after-sales service centre.

Maintenance and Service

Maintenance and Cleaning

Check the measuring tool before each use. If the meas-
u
uring tool is visibly damaged or parts have become loose
inside the measuring tool, safe function can no longer be
ensured.
Always keep the measuring tool clean and dry to ensure op-
timum, safe operation.
Never immerse the measuring tool in water or other liquids.
Wipe off any dirt using a dry, soft cloth. Do not use any de-
tergents or solvents.
Do not remove the contact pads (6) on the rear side of the
measuring tool.
