Note A wall bracket or tripod may be used as mounting devices. The angle of inclination of the surface on which it stands should not exceed ± 5°. 5.5 Manual horizontal alignment Note The rotating laser is mounted on the PRA 90 automatic tripod. The PRA 30 laser receiver, the rotating laser and the PRA 90 automatic tripod are paired.

5.9 Setting the inclination using the PRA 79 slope adapter Note Depending on the application, the PRA 79 slope adapter can be mounted on a tripod. The angle of inclination of the PRA 79 slope adapter is set to 0°. 1.
Page 17
◁ If no button is pressed within 3 seconds, the rotating laser levels itself to the previously set value. The inclined plane mode LED lights. Note A long press of the button causes the entered value to change rapidly. Note When the angle of inclination is set manually, the rotating laser levels the laser plane once and then fixes it.
Page 18
Note If the rotating laser begins the automatic search in the wrong direction, press the button to change the search direction. 5.12 Alignment using electronic inclination alignment (e-targeting) Note Electronic inclination alignment optimizes manual alignment of the rotating laser. The electronic method is more accurate.
