Hoekmetingen
1.
Place a wedge under the transmitter TX and under the receiver RECV and make sure that the centre
line of both devices points in the direction of the required drilling point (see Fig. l).
2.
Drill the hole (see Fig. m).
If accurate positioning and alignment are not possible, for example when drilling in corners, the device
can be aligned using two identical wedge-shaped supports. The angles of the wedges must match the
required drilling angle.
Different wedge angles can result in misplaced holes. Always use identical wedges.

Information on maintenance and care
Clean all components with a damp cloth and do not use cleaning agents, scouring agents and solvents.
Remove the battery(ies) before storing for longer periods. Store the device in a clean and dry place.

Multipoint measurement
1.
Mark at least two, preferably four, reference points at precisely the same distance from the intended
drilling point (see Fig. j).
2.
The corrected drilling point is located at the geometric centre point of the reference points (see Fig. k).
Operation in increased tolerance mode slightly reduces the accuracy of drilling point positioning.
!
Tip:
Interference caused by metal can prevent the drilling point being located. In these rare cases, the four
square LED indicators will not light up at any point. The tolerance of the receiver RECV can be increased
by briefly pressing the ON/OFF button (11). The setting is confirmed by a longer acoustic signal. The device
reverts to normal operating mode by pressing the ON/OFF button (11) again or switching off the device.
