Starting operation

Protect the laser receiver against moisture and direct sunlight.
u
Do not subject the laser receiver to extreme temperatures or variations in tem-
u
perature. As an example, do not leave it in vehicles for longer periods. In case of large
variations in temperature, allow the laser receiver to adjust to the ambient temperat-
ure before putting it into operation. In case of extreme temperatures or variations in
temperature, the accuracy of the laser receiver can be impaired.
Keep the work area free from obstacles that could reflect or obstruct the laser
u
beam. For example, cover any reflective or shiny surfaces. Do not measure
through panes of glass or similar materials. The measurements may be distorted
by a reflected or obstructed laser beam.
Setting up the laser receiver (see figure A)
Place the laser receiver at least 0.5 m away from the rotary laser. For rotary lasers with
multiple operating modes, select the horizontal or vertical operation with the highest ro-
tational speed.
Position the laser receiver so that the laser beam can reach the reception area (6). Align
it so that the laser beam runs straight through the reception area (as shown in the fig-
ure).
Switching On/Off
A loud audio signal sounds when switching on the laser receiver. Therefore, keep
u
the laser receiver away from your ear or other persons when switching it on. The
loud sound can damage hearing.
To switch on the laser receiver, press the on/off button (1). All display indicators light
up briefly and two audio signals sound.
After the laser receiver is switched on, the measuring accuracy is always set to "medium"
and the audio signal is always switched off.
To switch off the laser receiver, press the on/off button (1) again.
If no button on the laser receiver is pressed for approx. 10 min and no laser beam
reaches the reception area (6) for 10 min, the laser receiver will automatically switch it-
self off to preserve battery life. An audio signal indicates when the laser receiver is
switching off.
