5.1. MODE SELECTION
When scanning for studs, there are three scan modes to choose
for properly thick of the scanning surface:
1/2" Scan Mode scans through surfaces up to 1/2 inch thick.
1" Scan Mode scans through surfaces up to 1 inch thick.
1-1/2" Scan Mode scans through surfaces up to 1-1/2 inch thick.
If the thick of the scanning surface is unknown, you can start with 1-1/2"
Scan Mode. And then choose more suitable Scan Mode to verify the
centre of studs again.
When scanning for metal pipes or rebar, select Metal Mode.
When scanning for electrical wires, select AC Mode.
5.2 HOW TO USE
IMPORTANT OPERATING TIPS,PLEASE READ CAREFULLY
Tool Position: For proper use, always place scanner flat against the surface
before turning on power.

Power: Depress and hold in the Scan button continuously while in use.
Calibration: Place unit flat on wall. Press and hold the Scan button. Do not
move the unit until calibration is complete (1-2 seconds). When calibration is
complete, the unit will sound a short beep and the bars will be cleared.
Operation: Move the unit slowly, while keeping it flat against the wall. Do not
rock or lift it.
5.3. SCANNING IN STUD MODE
After calibrating (see2), continue to hold the scan button and slowly
slide the unit across the surface. As you approach the edge of a stud,
bars on the display will indicate you are getting close. Continue moving the
scanner slowly until the display indicates the EDGE of the stud, (see the picture
below).
Continue moving the scanner slowly. The audio signal and display
will indicate the CENTER of the stud.
Continue in the same direction to find the other edge.
5.4. SCANNING IN METAL OR AC MODE
AC Wire Warning
Always verify the unit is in good working order before use.
You can test it in a known correctly wired socket or distribution board.
For your safety, AC Wire Warning works continuously in all modes.

Caution: Wires deeper than 2in.(51mm),in conduit, or behind plywood
shear wall may not be detected. Use extreme caution under these
circumstances or whenever hot AC wires are present. Always turn off power
when working near electrical wires.
Select mode. After calibrating (see 2), continue to hold the scan button and

slowly slide the unit across the surface. Mark the spot where the display bars
peak and a steady tone sounds. Continue in the same direction until display bars

that direction. The midpoint of the two marks is the approximate center of the
object, (see the picture below)
