6.6.2 Alignment using the PRA 90 automatic tripod
NOTE
This function is available only with the PRA 90 automatic tripod.
When used for the first time, the PRA 300 laser receiver must be paired with the tripod (see 6.9.2).
With the optional PRA 90 automatic tripod you can set the height of the laser plane to the desired level manually or
automatically.
1. Mount the tool on the PRA 90 automatic tripod.
2. Switch on the rotating laser, the automatic tripod and the laser receiver. Set the height of the laser plane manually
(see 6.6.2.1) or automatically (see 6.6.2.2).

6.6.2.2 Automatic alignment 6 12
1. Hold the laser receiver at the desired height with the detection area facing the PRA 90 control panel. Hold the
laser receiver still while alignment is taking place and take care to ensure that the line of sight between the laser
receiver and the tool is not obstructed.
2. Press the "Automatic alignment" key
the key again to complete the procedure.
The laser plane alignment process is then started, i.e. the tripod elevates or lowers itself to the required height. A
constant signal tone is emitted while this is taking place. As soon as the laser beam strikes the detection area of
the laser receiver, the beam moves to the position of the marking notch (reference plane). After the position has been reached and the rotating laser has leveled itself, a signal tone with a duration of 5
seconds indicates that the process is complete. The "Automatic alignment" symbol
3. Check the height settings in the display.

receiving area.
6.7 Working in the vertical plane
1. When working in the vertical plane, mount the tool on a suitable tripod, facade adapter, batter board adapter or
wall bracket, with the control panel facing upwards. Alternatively, the tool can be stood on the rubber feet on the
rear grips.
NOTE The best wireless connection with the PRA 300 is provided by the side of the tool to the right of the control
panel.
NOTE In order to ensure that the tool's specified accuracy can be maintained, make sure that it is set up on a
level surface or mounted sufficiently level on the tripod or other accessory.
2. Use the visual sighting method (front and rear sights) to align the rotating laser in the desired direction.
