◁
The rotating laser levels itself once the position has been reached. The symbol is displayed
briefly.
▽
If automatic alignment cannot be completed successfully, short signal tones are emitted and the
is displayed briefly.
5.
Double-click the button on the PRA 30G laser receiver.
◁ During automatic alignment: Stops automatic alignment before completion.
5.9 Automatic vertical alignment with surveillance function
The rotating laser is placed or securely mounted in the vertical position (tripod, wall mount, facade or
batter board adapter, or lying on the rear grips). A reference point (A) is marked below the laser head
(e.g. a nail on a batter board or a spot of paint on the floor or ground).
The PRA 30G laser receiver and the rotating laser are paired.
The PRA 30G laser receiver and the receiving side of the rotating laser are facing each other and in
direct line of sight. The best receiving side of the rotating laser is the side at which the battery is inserted.
1.
Press the button on the rotating laser.
◁ The rotating laser levels itself and then projects a stationary downward-pointing laser beam.
2. Position the rotating laser so that the projected laser beam strikes reference point (A) exactly. Please
note: The reference point is not a plumb point!
3. Keep the marking notch on the PRA 30G laser receiver on the plane that is to be set. The PRA 30G laser
receiver should be held steady or secured in place.
4.
Press the button on the PRA 30G to display the AUTO menu. Start automatic alignment with
surveillance function .
◁ The head of the rotating laser pivots to the left and right until the position is reached. An signal tone
is emitted by the laser receiver repeatedly during this procedure.
◁
The rotating laser levels itself once the position has been reached. The symbol is displayed
briefly and the signal tone stops.
◁ The rotating laser switches to the surveillance function. Small deviations due to external influences
are then compensated automatically and the laser beam is kept at the height of the marking notch on
the laser receiver.
▽
If automatic alignment cannot be completed successfully, short signal tones are emitted and the
is displayed briefly.
5. Do NOT remove the PRA 30G laser receiver from the target plane so long as surveillance mode is active.
6.
Double-click the button on the PRA 30G laser receiver.
◁ During automatic alignment: Stops automatic alignment before completion.
◁ If the surveillance function is active: Deactivate (end) the surveillance function.
5.10 Setting the inclination manually
The rotating laser, depending on the application, is mounted or positioned securely.
The PRA 30G laser receiver and the rotating laser are paired.
The PRA 30G laser receiver and the receiving side of the rotating laser are facing each other and in
direct line of sight. The best receiving side of the rotating laser is the side at which the battery is inserted.
