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.
Settings menu
To call up the settings menu: Briefly press the X-axis
button (16) and the Y-axis button (15) on the laser receiver
at the same time.
To change the setting within a submenu: Press the X-axis
button (16) or the Y-axis button (15) to switch between the
settings. The last selected setting is automatically saved
when exiting the menu.
To change the submenu: Briefly press the CenterFind
mode button (17) to move to the next submenu.
To exit the settings menu: Press and hold the CenterFind
mode button (17) until the settings menu closes. Alternat-
ively, the settings menu is automatically closed approxim-
ately 10 seconds after the last press of a button.
The following submenus are available:
– Unit of measurement of the relative height indicator:
When calling up the unit of measurement menu, the cur-
rently selected unit of measurement is shown in the text
display (e), while the available units of measurement are
shown in the unit of measurement indicator (d) above it.
– LED direction indicators (LED): The 3 LED direction
indicators (2), (4) and (3) can be adjusted with regard to
their brightness or switched off. The LEDs light up in their
selected setting.

– Display lighting (LIT): The display lighting can be
switched on (green LED lights up) or switched off (red
LED lights up).
– Memory function for last reception (MEM): The indic-
ator for the direction in which the laser beam has left the
reception area can be switched on (green LED lights up)
or switched off (red LED lights up).
– Centre functions (CF/CL) (LR 65 G): You can choose
between CenterFind (CF) mode and CenterLock (CL)
mode. The current mode appears in the text display (e).
With the exception of the setting for the display lighting, all

Functions
CenterFind mode (see figure C)
In CenterFind mode, the rotary laser automatically attempts
to align the laser beam to the centre line of the laser receiver
by moving the rotation head up and down.
If the rotary laser is in the horizontal position, the laser
beam can be aligned in relation to the X-axis of the rotary
laser, to the Y-axis or to both axes at the same time (see "In-
clination determination with CenterFind mode (see
figure D)", page 19). If the rotary laser is in the vertical po-
sition, only alignment to the Y-axis is possible.
Start CenterFind mode:
Position the rotary laser and laser receiver so that the laser
receiver is situated in the direction of the X-axis or the Y-axis
of the rotary laser. Align the laser receiver so that the re-
quired axis is at a right angle to the reception area (1).
If the laser beam is aligned to both axes, then place a laser
receiver connected to the rotary laser in the direction of the
X- and Y-axis respectively. Each laser receiver must be situ-
ated within the pivoting range of ±8.5 % of the rotary laser.
Switch on the rotary laser in rotational operation.
LR 65 G: In the settings menu, the centre function must be
put in CenterFind (CF) mode. When aligning to two axes of
the rotary laser, this applies to both laser receivers.
To start the CenterFind mode for the X‑axis, either press
and hold the CenterFind (17) mode button, or press and
hold the CenterFind (17) mode button, together with the
X‑axis button (16).
