Power Cable
When a live conductor is detected, the display 3 also indi-
cates a . The LED 2 flashes red and the signal sounds with
a quick tone sequence.
Notes:
"Live" conductors are indicated in any operating mode.
"Live" conductors can be detected easier when power con-
sumers (e.g. lamps, machines) are connected to the sought
conductor and switched on.
Under certain conditions (such as below metal surfaces or
behind surfaces with high water content), "live" conduc-
tors cannot be securely detected. The signal strength of a
"live" conductor depends on the position of the cable. There-
fore, apply further measurements in close proximity or use
other information sources to check if a "live" conductor exists.
Static electricity can lead to electric lines being indicated in-
accurately, e.g. over a large area, or not at all. To improve the
indication, place your free hand flat on the wall next to the
measuring tool, in order to remove the static electricity.
 Hold the measuring tool only at the intended grip area
10, so as not to influence the measurement.

Maintenance and Service

Maintenance and Cleaning

 Check the measuring tool each time before use. In case
of visible damage or loose components inside the measur-
ing tool, safe function can no longer be ensured.
Keep the measuring tool clean and dry at all times to ensure
proper and safe working.
Do not immerse the measuring tool in water or other fluids.
Wipe away debris or contamination with a dry, soft cloth. Do
not use cleaning agents or solvents.

Marking Objects
If required, detected objects can be marked. Perform mea-
surement as described. Once you have found the boundaries
or the centre of an object, mark the sought location at the top
marking aid 1 and the side marking aid 4. Connect both points
with a vertical and horizontal line. The object is located at the
intersection of the lines.

Working Advice

Temperature Control
Note: If the device is lifted off the wall, a signal may be shown
temporarily.
When the temperature control indicator e lights up, the bat-
tery of the measuring tool is not within the operating temper-
ature range or was subject to large variations in temperature.
Change the battery or wait until it has once again reached
the operating temperature range.
Warning Function
When the display 3 indicates f and g send the measuring tool
to an authorised customer service agent. The measuring tool
is no longer functional.
Cause
Battery pack empty
Batteries empty
Measuring tool has a fault
In order not to affect the measuring function, decals/stickers
or name plates, especially metal ones, may not be attached in
the sensor area 14 on the front or back side of the measuring
tool.
If the measuring tool should fail despite the care taken in man-
ufacturing and testing procedures, repair should be carried
out by an authorised after-sales service centre. Do not open
the measuring tool yourself.
In all correspondence and spare parts orders, please always
include the 10-digit article number given on the type plate of
the measuring tool.

Corrective Measure
Charge battery pack
Replace batteries
Remove and reinsert rechargeable
batteries/batteries
Send measuring tool to customer ser-
vice agent
Wait until the permitted temperature
range of the battery has been reached
or change the battery
If possible, remove the interfering ra-
dio waves, e.g. WLAN, UMTS, radar,
transmitter masts or microwaves.
