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.
Setting up the Laser Receiver (see figure A)
Place the laser receiver at least 5 m away from the line laser. Ensure that receiver mode
is active on the line laser. Select an operating mode in which either only a horizontal or
only a vertical laser plane is generated.
Note: Do not select an operating mode which generates both horizontal and vertical
laser planes at the same time (cross-line operation) because this might impair the height
readings of the laser beam.
Position the laser receiver so that the laser beam can reach the reception area (9). 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 (2). All LEDs light up briefly and
an audio signal sounds.
After the laser receiver is switched on, the volume is always set to low and the reception
accuracy set to "fine".
To switch off the laser receiver, press the on/off button (2) again. Before switching off,
all LEDs light up briefly and three audio signals sound. The status indicator (3) goes out.
If no button on the laser receiver is pressed for approx. 20 min and no laser beam
reaches the reception area (9) for 20 min, then the laser receiver will automatically
switch itself off to preserve battery life.
Selecting the setting of the centre line indicator
You can use the button for adjusting the reception accuracy (1) to specify the accuracy
with which the position of the laser beam is indicated as "centred" on the reception area:
– Reception accuracy "fine" (the centre line LED (7) flashes),
– Reception accuracy "coarse" (the LED direction indicators "Laser beam over centre
line" (6) and "Laser beam under centre line" (8) flash).
