To determine drilling position
1. With special adhesive on the back, securely position the transmitter at the required drilling point
on the wall or ceiling (see Fig. a).
2. Switch on transmitter and receiver.
3. Move the receiver on the other side of the wall/ceiling (see Fig. b). With red arrows,
the positioning LEDs (7) show the direction of movement. Green squares show that the positions
of the transmitter and receiver are aligned.
4. Positioning is correct when the four green squares light. After marking the drilling point (see Fig. c),
remove the devices from the wall/ceiling and drill the hole.
!
Remove the devices from the wall/ceiling before drilling.
Drilling through the marking aid aperture is at your own risk.

The positioning LEDs (7) are suitable for determining drilling depths
of up to 120 cm.
At depths >120 cm, the drilling point can be set by determining
the minimum drilling depth with the aid of the LC display (9).
To do so, move the receiver over the wall on the X and Y axis and
mark the positions on reaching the minimum drilling depth shown
on the display from all four directions (right, left, top, bottom to
imaginary centre point).
The four markers are on a coordinate cross (X/Y-axis) with its centre
point corresponding to the required drilling position.
