Laser receiver too high: If the laser beam
hits the lower half of the reception area (1),
then the "laser beam below center line" direc-
tion indicator (f) appears in the display. If the
LEDs are switched on, the red "laser beam
below center 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 arrow. When the laser beam
is close to the center line, only the tip of the
"laser beam below center line" direction indi-
cator (f) is shown.
Laser receiver centered: If the laser beam
hits the reception area (1) at the height of
the center line, then the center line indica-
tor (h) appears in the display. If the LEDs are
switched on, the green center line LED (3)
lights up. If the audio signal is switched on, a
continuous tone sounds.
Memory function of last reception: If the la-
ser receiver is moved so that the laser beam
leaves the reception area (1) again, the last
displayed direction indicator for "laser beam
above center line" (j) or "laser beam below
center line" (f) flashes for a short time. This
indicator can be switched on or off via the set-
tings menu.
Relative height indicator (see figure B)
If the laser beam hits the reception area (1),
the clearance between the laser beam and
the center line of the laser receiver 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").
Display illumination
The displays (5) on the front and rear of the
laser receiver can be illuminated. The display
illumination function is switched on:
– When the laser receiver is switched on
– With each press of a button
– If the laser beam moves over the reception
area (1).
The display illumination function automati-
cally switches off:
– 30 s after each button press, if no laser
beam reaches the reception area
– 2 mins after no button press and laser
beam has not moved

The display illumination function can be
switched off in the settings menu. Setting is
not saved after receiver is turned off. Back-
light is always on when turning receiver on.
Settings
Selecting the setting of the center line
indicator
You can specify the accuracy with which the
position of the laser beam is indicated as
"centered" on the reception area (1).
The current setting for the center line indica-
tor (c) can be seen in the indicator for mea-
suring accuracy.
To change the measuring accuracy, press the
button for adjusting the measuring 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 measur-
ing accuracy, the respective value for the mea-
suring accuracy appears in the text display (e)
for a short time.
The setting for measuring accuracy is saved
when the tool is switched off.
Laser Beam Indicator Audio Signal
The position of the laser beam on the recep-
tion area (1) can also be indicated by an audio
signal.
You can adjust/change the volume or switch
off the audio signal.
To change the volume level or switch off the
audio signal, push the audio signal button
(20) until the required volume level is indi-
cated on the display. At a low volume, the au-
dio signal indicator (g) appears on the display
with one bar; at a high volume, the indicator
appears with three bars. When the audio sig-
nal 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,
as well as when the laser beam first makes
contact with the reception area (1).
The setting for the audio signal is saved when
the laser receiver is switched off.
