line" direction indicator (j) appears in the display.
If the LEDs are switched on, the blue "laser beam above
centre line" LED direction indicator (2) lights up.
If the audio signal is switched on, a signal sounds in a slow
rhythm.
Move the laser receiver upwards in the direction of the ar-
row. When the laser beam is close to the centre line, only the
tip of the "laser beam above centre line" direction
indicator (j) is shown.
Laser receiver too high: If the laser beam hits the lower half
of the reception area (1), then the "laser beam below centre
line" direction indicator (f) appears in the display.
If the LEDs are switched on, the red "laser beam below
centre line" LED direction indicator (4) lights up.
If the audio signal is switched on, a signal sounds in a fast
rhythm.
Move the laser receiver downwards in the direction of the ar-
row. When the laser beam is close to the centre line, only the
tip of the "laser beam below centre line" direction
indicator (f) is shown.
Laser receiver centred: If the laser beam hits the reception
area (1) at the height of the centre line, then the centre line
indicator (h) appears in the display.
If the LEDs are switched on, the green centre line LED (3)

If the audio signal is switched on, a continuous tone sounds.
Memory function of last reception: If the laser receiver is
moved so that the laser beam leaves the reception area (1)
again, the last displayed direction indicator for "laser beam
above centre line" (j) or "laser beam below centre line" (f)
flashes for a short time. This indicator can be switched on or
off via the settings menu.
Relative height indicator (see figure B)
If the laser beam hits the reception area (1), the clearance
between the laser beam and the centre line of the laser re-
ceiver is shown in the text display (e) as an absolute value.
The measuring unit for the height indicator can be changed
in the settings menu ("mm" or "in").

The display illumination function automatically switches off:
– 30 s after each button press, if no laser beam reaches the

laser beam in the reception area does not change.
The display illumination can be switched off in the settings

Settings
Selecting the setting of the centre line indicator
You can specify the accuracy with which the position of the
laser beam is indicated as "centred" on the reception
area (1).
The current setting for the centre line indicator (c) can be
seen in the indicator for reception accuracy.
To change the reception accuracy, press the button for ad-
justing the reception accuracy (18) as many times as
needed for the required setting to be shown in the display.
With each press of the button for adjusting the reception ac-
curacy, the respective value for the reception accuracy ap-
pears in the text display (e) for a short time.
The setting for reception accuracy is saved when the tool is
switched off.
Laser Beam Indicator Audio Signal
The position of the laser beam on the reception area (1) can
also be indicated by an audio signal.
The volume level can be changed or the audio signal
switched off.
To change the volume level or switch off the audio signal,
push the audio signal button (20) until the required volume
level is indicated on the display. At a low volume, the audio
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 when the laser beam first makes contact
with the reception area (1).
The setting for the audio signal is saved when the laser re-
ceiver is switched off.
