Audio Signal for Indication of the Laser Beam
The position of the laser beam on the reception area 5 can be
indicated via an audio signal.
After the tool has been switched on, the audio signal is always
set to the medium volume level.
The volume level can be increased or switched off.
To change the volume level or switch off the audio signal, push
the audio signal button 4 until the requested volume level is indi-
cated on the display. At low volume level, the audio signal indica-
tor g appears on the display with one bar; at high volume level,
the indicator appears with three bars. When the audio signal is
set to off, the indicator goes out.
Independent of the audio signal setting, every time a button on
the tool is pressed, then a short, low-volume beep sounds.
Backlight
When switched on, backlight power is brightest.
When there is no detection or user interaction after 2 minutes,
then the backlight is half as bright.
To completely turn off the backlight, then press or hold both the
audio signal button 4 and accuracy button 1 for 2 seconds.
Working Advice
Marking
When the laser beam runs through the center of the reception
area 5, its height can be marked at the center mark 11 right and
left on the tool.
When marking, make sure to align the tool for each laser beam,
both vertically and horizontally. If this is not done, then the marks
will be offset from the laser beam.
Attaching with the Magnet (see figure B)
When a positive-lock attachment is not absolutely required, then
the magnets 7 on the top side of the tool can be used to attach
the tool to steel parts.
