Warning
In some cases, live wires in walls may not be able to accurately indicated because of internal equipment malfunctions
or improper operation, so do not identify the presence of dangerous live wires totally dependent on the instrument, other
evidences, such as construction drawings or visual identification of wiring or pipe entrance, should also be adopted.
Never take any dangerous operation if there is any live wires in the wall. Be sure to turn of f power, gas, and water
before turning holes or studding the wall.
Concrete, brick, and ceramic surfaces have shielding effects on electric field signals of firing line, which means AC
signal detection will be affected.
AC signals can be easier to be detected when the consumer is connected to the required conductor and turned on.
Signals from live wires will spread from both sides of the actual wire, so sometimes the area of live wire alarms looks
much larger than the actual wire.
AC signals come mainly from live wires, and may also come from static or induced electricity of the environment.
Placing your hand on the wall may help eliminate static and inductive electricity.
The signal strength of a live wire depends on the location of the cable. Therefore, please take further measurements
nearby or use other information to check for live wires.
Non-live wires may be detected as metal objects, and thin wires may not be detected.
7.3 Foreign Body Detection(generally for the wooden batten):
Maximum detection depth: Accurate mode: 20mm; Deep mode: 38mm. Long press the button 1 to switch between
Accurate and Deep modes.
The foreign body detection mode is for objects in gypsum drywall, plywood, solid wood, and coated wood walls.
This mode can't detect objects in concrete, mortar, lumps, bricks, carpets, foils, metal surfaces, tiles, glass or any
other non-uniform density materials.
Sensitivity depth and accuracy will vary by moisture, material content, wall texture and paint.
The foreign body detection mode actually detects more than just wood batten. It can also detect metals and other
dense materials.
Figure 7
1.Signal area and center icon. The center icon appears when the signal reaches
Figure 10
maximum.
2.The current maximum depth of detection is 20mm, Long press the button 1 to
switch to maximum depth 38mm.
3.When the center icon is displayed, the properties of the currently measured
object are displayed here, as follows:
indicates that the measured object is a wooden beam
indicates that the subject is an iron nail
indicates that the measured object is light steel keel
indicates that the measured object is cable
indicates can't be distinguished between cable and nail
4.This icon is displayed only when the measured object is detected as cable and
simultaneously detects an AC electrical signal.
1) Press the wood button to enter the foreign body detection mode (as shown in Figure 7), and speaker will indicate
the current detection mode (mute if the sound is turned off).
2) When detecting foreign bodies, the instrument must be vertically attached to the wall and then press the button to
detect. Keep the instrument stay for 1-3s and the instrument calibration will be completed (as shown in Figure 7 and
Figure 8) before conducting the detection operation. Place the sensor on the surface of object and move it evenly
and slowly in the same direction to the left or right, without lifting or applying additional pressure.

Figure 9
3) When the instrument detects foreign matter, the screen displays signal the strength synchronously (as shown in
Figure 9).
4) Continue to move the instrument in the same direction. When the instrument is in the middle of wooden batten, Icons
1 and 3 in Figure 9 will be displayed.
5) At this time, keep moving in the same direction. When the instrument leaves the center of the measured object, the
screen will display the interface as Figure 9. Continue to move the instrument away from wooden block, the signal
gradually decreases until there is no signal. The display screen displays as shown in Figure 9, and the detection
operation is completed.
Note: repeat the detection, the location will be more accurate.
Please note:
Sometimes due to various environmental factors, the instrument may not be automatically calibrated, and there may
be wrong alarm signal, please calibrate manually . Short press the button of foreign body detection mode, and the
screen displays the interface as Figure 9.
If the instrument has just been calibrated on the wooden batten, move the tool out of the wooden batten scope and
only detect it when the wooden batten is tested again.
If you receive erratic results, it may because of moisture in the wall cavity or drywall, or the recent application of
partially dried paint or wallpaper. While moisture may not always be visible, it can interfere with the sensors. Please
let the walls dry for a few days.
For some environmental factors or uneven surfaces, it is dif ficult to detect wood studs with foreign body detection
mode. It may be easier to detect by the metal detection mode, which can locate the nails that hold the material to the
wood nails.
Depending on how close the wire or pipe is to the wall, the instrument can detect them it as same as foreign body
detection. Always be careful when nailing, cutting or drilling walls, floors and ceilings that may contain these items.
8. Maintenance and Cleaning
In order to ensure the good performance of sensor, please follow the instructions below to maintain:
Please do not expose the instrument to extreme cold or hot environment, and do not put external pressure or vibration
on it for a long time.
The product is required to be stored indoors. When it is not in use, please place it in box.
Avoid using the product in the dusty and damp environment. Wipe the dirt of the product by a soft damp cloth to
clean the product. Do not use corrosion, volatile substances, detergent or solvents.
Please replace the battery when the battery status is displayed as low on screen.
Please do not disassemble the instrument without permission to avoid laser damage.
Do not change any optical component of the lens.

Do not put any label or nameplate on the detection area (front and rear) of instrument. Especially do not put any
metal nameplate.
Store and carry the instrument with the attached protective bag.
9. Disposal of Waste
Damaged instruments, accessories and packaging materials must be recovered and reused in an environmentally
friendly manner.
