NOTES:
1. The stud detection can be carried out normally on wall-papered
walls. However, it may not function on some types of foil backed
or metallic fabric surfaces.
2. If by chance the unit is placed over the wall batten or stud to
process calibration, the GREEN LED will go off and BUZZER will
cease when the edge of batten or wall stud is under the groove of the unit.
3. A double width may be found around door and window frames due to double batten or stud
encountered.
4. A solid wood header may exist in some doors or windows. The stud location will not be found if
the unit is calibrated on normal wall first and then moved to the header area, it will indicate the
presence of a header.
5. It is advisable to take several readings along the vertical batten or stud as a nail may change
the apparent centre position.
6. Frequent re-calibration can help to avoid any false readings.
7. We recommend to carry out metal/voltage detection to make sure the detected batten or wood
stud is not a pipe or cable. Please note that some small securing screws or nails may be
detected.

OPERATION WOOD FRAME
DETECTION PROCEDURE
WOOD FRAME DETECTION PROCEDURE:
Locating vertical battens or wall studs, refer to the following
procedures:
1. Hold the unit vertically as shown (fig.6) and turn the adjusting
dial fully downwards.
2. Move the selector switch to STUD DETECTOR position.
3. Turn the adjusting dial upwards until the RED LED and
BUZZER come on.
4. Reverse the adjusting dial gently until the GREEN LED comes
on and BUZZER sound changes to a low pitch.
5. If the unit cannot be set accordingly, it needs to be adjusted.
For details please refer to ‘UNIT ADJUSTMENT’ (see section on
“Accuracy/Calibration”).
6. Move the unit horizontally across the wall (fig.7). Make sure
that the detection face marked with “STUD” is placed against
the wall, otherwise, the GREEN LED will go out and calibration
procedures need to be carried out from the beginning.
7. When the edge of batten or wall stud is under the groove of
the unit, the RED LED will come on and buzzer sound will
change to a higher pitch. Mark this position on the wall (fig.8).
8. Resume the movement of the unit. When the GREEN LED
comes on and BUZZER sound changes to a lower pitch, mark
this position also. These marks indicate the edges of the
batten or wall stud. The middle point between two marks will
be the centre of the batten or wall stud.
Locating horizontal battens or stud braces, refer to the following
procedure:
1. Place the unit horizontally against the wall (fig.9).
2. Use the same method of locating vertical battens or wall studs
