Audio Signal for Indication of the Laser Beam

volume levels.
To switch on the audio signal or change the volume level, push the

ed. At medium volume level, the audio signal indicator e in the dis-
play flashes; at high volume level, the indicator is continuously lit.
When the audio signal is set to off, the indicator goes out.

Working Advice

Marking
When the laser beam runs through the center of the reception area
6, its height can be marked at the centre mark 5 right and left on
the measuring tool. The centre mark is located 45 mm away from
the top edge of the measuring tool.
Aligning with the Spirit Level
The measuring tool can be aligned vertically (plumb line) with the
spirit level 8. A measuring tool applied out-of-level leads to faulty
measurements.
