Direction Indicators
The position of the laser beam in the reception area (9) is indicated as follows:
– By the direction LEDs "Laser beam above centre line" (6), "Laser beam below centre
line" (8) or centre line indicator (7) on the front and back of the laser receiver,
– optionally by the audio signal.
Laser receiver too low: If the laser beam hits the upper half of the reception area (9),
then the "Laser beam above centre line" LED direction indicators (6) light up.
If the audio signal is switched on, a signal sounds at a high frequency.
Move the laser receiver upwards in the direction of the arrow.
Laser receiver too high: If the laser beam hits the lower half of the reception area (9),
then the "Laser beam below centre line" LED direction indicators (8) light up.
If the audio signal is switched on, a signal sounds at a low frequency.
Move the laser receiver downwards in the arrow direction.
Laser receiver centred: If the laser beam hits the reception area (9) at the height of the
centre mark (12), then the centre line LEDs (7) light up.
If the audio signal is switched on, a continuous tone sounds.
Laser Beam Indicator Audio Signal
The position of the laser beam on the reception area (9) can also be indicated by an au-
dio signal.
The volume level can be changed or the audio signal switched off.
To change or switch off the audio signal, press the audio signal button (4). When the
volume is low, a brief audio signal will sound and the centre line indicator LED (7) will
light up. When the volume is high, a brief audio signal will sound and the LED direction in-
dicators (6), (7) and (8) will light up. When the audio signal is switched off, the LED in-
dicators go out.
Independent of the audio signal setting, a short beep sounds at low volume level each
time a button is pressed on the laser receiver.
Working Advice
Marking
You can mark the height of the laser beam at the centre mark (12) on the left and right of
the laser receiver when the beam hits the centre of the reception area (9).
When marking, take care to align the laser receiver so that it is exactly vertical (with a ho-
rizontal laser beam) or horizontal (with a vertical laser beam), as otherwise the marks are
offset with respect to the laser beam.
