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 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.
Settings menu
To call up the settings menu: 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 but-
ton (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 set-
tings menu closes. Alternatively, the settings
menu is automatically closed approximately
ten seconds after the last press of a button.
All settings are saved when the laser receiver
is switched off. Except the display backlight
setting. It is always on when turning the re-
ceiver on.
The following submenus are available:
– Unit of measurement of the relative height
indicator: When calling up the unit of mea-
surement menu, the currently selected
measuring unit is shown in the text display
(e), while the available measuring units are
shown in the measuring unit indicator (d)
above it.
– LED direction indicators (LED): The three
LED direction indicators (2), (4) and (3)
can be adjusted with regard to their bright-
ness 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
(MEM): The indicator for the direction in
which the laser beam has left the reception
area can be switched on (green LED lights
for last reception
up) or switched off (red LED lights up).
– Center functions (CF/CL): You can choose
between CenterFind (CF) mode and Cen-
terLock (CL) mode. The current mode ap-

Functions
CenterFind mode (see figure C)
In CenterFind mode, the rotary laser auto-
matically attempts to align the laser beam to
the center 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 "Inclination
Determination with CenterFind mode (see
figure D)", page 4). If the rotary laser is in the
vertical position, 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 direc-
tion 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
situated within the pivoting range of ±8.5% of
the rotary laser.
Switch on the rotary laser in rotary operation.
In the settings menu, the center 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 CenterFind mode for the X-axis, ei-
ther press and hold the CenterFind (17) mode
button, or press and hold the CenterFind (17)
mode button together with the X-axis button
(16). To start CenterFind mode for the Y-axis,
press and hold the CenterFind (17) mode
button, together with the Y-axis button (15).
Should the laser beam be aligned to both axes
at the same time, CenterFind mode must be
started separately on each laser receiver.
Following the start of CenterFind mode, the
rotary head on the rotary laser moves up and
down. During the search process, CFX (X-axis)
or CFY (Y-axis) appears in the text display (e).
If the laser beam hits the reception area (1)
at the height of the center line of the laser re-
