Bosch Power Tools
Depending on the size and depth of the object located within
the sensor range, it may not be possible to determine with
complete certainty whether the object is live. If this is the
case, the symbol
?
appears on the display
(n)
.
Live cable (see figure C)
A live, metal object, e.g. an electrical cable, is located within
the sensor range. The permitted drilling depth is 1.5 cm. The
measuring tool emits the warning signal for live cables as
soon as the sensor detects an electrical cable.
Iron rod (see figure D)
A magnetic object, e.g. an iron rod, is located within the
sensor range. Other objects that are outside the sensor
range are located to the left and right of the object. The per-
mitted drilling depth is 8.8 cm. The measuring tool emits an
audio signal.
Copper pipe (see figure E)
A metal object, e.g. a copper pipe, is located within the
sensor range. The permitted drilling depth is 4 cm. The
measuring tool emits an audio signal.
Plastic or wooden object (see figure F)
A non-metal object is located within the sensor range. The
object is plastic or wooden and is located close to the sur-
face. The measuring tool emits an audio signal.
Large flat object (see figure G)
A large, flat metal object, e.g. a metal plate, is located within
the sensor range. The permitted drilling depth is 2 cm. The
measuring tool emits an audio signal.
Numerous unclear signals (see figures H–I)
If numerous objects are shown on the default display screen,
the wall probably contains a large number of cavities (hollow
blocks). Switch the operating mode to
<Hollow block>
to
suppress most of the cavities. If the measuring tool contin-
ues to display too many objects, take multiple vertically off-
set measurements and mark the displayed objects on the
wall. Offset markings are an indication of cavities, whereas
markings in a straight line indicate an object.

ing lower two wheels stay in contact with wall; on un-
even surfaces, place thin piece of paper between wheels
and wall

and move measuring tool slowly
over wall
<Temperature over range>
Wait until it reaches the permitted temperature range

Wait until it reaches the permitted temperature range
<Strong radio signal detected>
Measuring tool switches off automatically. If possible,
remove the interfering radio waves, e.g. WLAN, UMTS,
radar, transmitter masts or microwaves, then switch the
measuring tool on again.
