Under certain conditions
WARNING
!
(such as when behind met-
alized or conductive surfaces, shielded
in metal conduit or behind surfaces with
high water content/moisture), "live" wires/
conductors cannot be detected with cer-
tainty. These ranges may be recognized as
metal objects. The signal strength of a "live"
wire/conductor depends on the position of the
cable. Therefore, apply further measurements
in close proximity or use other information
sources to check if a "live" wire/conductor
exists.
• Three-phase wiring is possibly not detected
as "live" conductor.
• Wires that are not "live" may be detected
as metal objects or may not be detected.
This includes solid copper cables, however
stranded copper cables are not detectable.
• Static electricity can lead to inaccurate de-
tection of electrical wires, especially, over a
large range. It may help to put a hand on
the wall next to the detector and measure
again in order to help remove the static
electricity.
Detection values can be

impaired through certain
ambient conditions. These include, but are
not limited to, the proximity of other equip-
ment that produces strong magnetic or
electromagnetic fields, moisture, metallic
building materials, foil-laminated insula-
tion materials or conductive wallpaper or
tiles. Therefore, please also consult other
information sources (e.g. construction plans)
before drilling, sawing or routing into walls,
ceilings or floors.
Before penetrating surface
WARNING
!
(such as with a drill,
router, saw or nail), always shut off the
electrical power, gas and water supplies.
Cutting, drilling, etc. into these items when
operational can result in personal injury.
Temperature Warning
The detector is equipped with a temperature
warning indicator, as accurate measurements
are only possible as long as the temperature
within the measuring tool remains constant.
When the temperature warning indicator g
lights up, the measuring tool is not within the
operating temperature range or was subject
to large variations in temperature. Switch
the detector off and allow it to adjust to the
ambient temperature before switching it on
again.
Warning Function
When indicator b lights up on display 3 and
indication 4 flashes above button 10, the
detection must be restarted. Remove the
detector from the wall and place it on the
surface at a different location.
When indicator b flashes on display 3, send
the detector to an authorized Bosch service
center.
