signal indicator (g) appears on the display with one bar; at a high volume, the indicator
appears with three bars. When the audio signal is switched off, the indicator goes 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.
Backlighting
The backlighting of the display is switched on at full strength when the laser receiver is
switched on. If no laser beam is detected and no button on the laser receiver is pressed
for 2 min, the backlighting is reduced by 50 %.
You can switch the backlighting off. To do so, press and hold the button for adjusting the
reception accuracy (2) and the audio signal button (4) at the same time for at least 2 s.
Working Advice
Marking
You can mark the position of the laser beam at the centre mark (10) on the left and right
of the laser receiver when the beam hits the centre of the reception area (5).
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.
Attaching using a magnet (see figure B)
If an attachment is not required to be especially secure, the laser receiver can be at-
tached to steel parts using the magnets (7).
