Selecting the Setting of the Centre Indicator
With button 2, you can specify with which accuracy the position of the laser beam is
indicated as central on the reception area:
– "Fine" adjustment, (indication g on the display),
– "Medium" adjustment, (indication b on the display).
An audio signal sounds when the accuracy setting is changed.
Whenever switching on the measuring tool, the accuracy level "medium" is set.
Direction Indicators
The bottom a, centre f and top d indicators (both on the front and rear side of the
measuring tool) indicate the position of the rotating laser beam in the reception area
6. Additionally, the position can be indicated with an audio signal (see "Audio Signal
for Indication of the Laser Beam", page 18).
Measuring tool too low: When the laser beam runs through the top half of the recep-
tion area 6, the bottom direction indicator a appears on the display.
When the audio signal is switched on, a slow-beat signal sounds.
Move the measuring tool upward in the direction of the arrow. When approaching the
centre mark 5, only the tip of the direction indicator a is indicated.
Measuring tool too high: When the laser beam runs through the bottom half of the
reception area 6, the top direction indicator d appears on the display.
When the audio signal is switched on, a fast-beat signal sounds.
Move the measuring tool downward in the direction of the arrow. When approaching
the centre mark 5, only the tip of the direction indicator d is indicated.
Measuring tool in centre position: When the laser beam runs through the reception
area 6 at the centre mark 5, the centre indicator f lights up. When the audio signal is
switched on, a continuous signal sounds.
Audio Signal for Indication of the Laser Beam
The position of the laser beam on the reception area 6 can be indicated via an audio
signal.
After the measuring tool has been switched on, the audio signal is always switched off.
When switching on the audio signal, you can choose between two volume levels.
– To switch on the audio signal or change the volume level, push the acoustic signal
button 3 until the requested volume level is indicated. At medium volume level, the
audio signal indicator e in the display flashes; at high volume level, the indicator is
continuously lit. When the audio signal is set to off, the indicator goes out.
