3 Description

3.1 Use of the product as directed
The tool can be used to remotely control the PR 300-HV2S rotating laser and to detect and locate the laser beam.
These operating instructions apply only to operation of the PRA 300 laser receiver. For information about the remote
control functions, please refer to the operating instructions for the PR 300-HV2S.
In conjunction with the PR 300-HV2S, the tool can be used to determine, transfer and check horizontal levels and
heights, verticals, inclined planes and right angles. Examples of its uses are: transferring datums and benchmark
heights, determining right angles for walls, vertical alignment on reference points and setting out slopes.
Observe the information printed in the operating instructions concerning operation, care and maintenance.
Take the influences of the surrounding area into account. Do not use the tool where there is a risk of fire or explosion.
Modification of the tool or tampering with its parts is not permissible.
3.2 Features
The tool can be held by hand or mounted on a leveling staff, timber batten or frame etc., using the applicable holder.

1 The drop test was carried out using the PRA 83 receiver holder, dropped onto flat concrete under standard ambient conditions
(MIL-STD-810G).
The position of the laser receiver relative to the height of the laser plane
is shown by an arrow indicating the direction in which the laser receiver
has to be moved in order to bring it exactly into alignment with the laser.
The battery status indicator shows the remaining battery capacity.
If no volume symbol is shown, the signal tone is switched off. If one seg-
ment is shown, the volume is set to "Low" (quiet). If two segments are
shown, the volume is set to "Normal". If three segments are shown, the
volume is set to "High" (loud).
Shows the exact distance of the laser receiver from the laser plane in the
desired unit of measurement.
Other indicators in the display refer to the PR 300-HV2S rotating laser
when controlled remotely. For further information, please refer to the
PR 300-HV2S operating instructions.
