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
center line mode button (17) to move to the
next submenu.
To exit the settings menu: Press and hold the
center line 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:
– Measurement unit of the relative height
indicator: When calling up the measuring
unit menus, the currently selected measur-
ing 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
up) or switched off (red LED lights up).
Functions
Center line mode (only with GRL4000-80)
(see figure C)
In center line mode, the rotary laser automati-
cally 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 "Inclina-
tion Determination with centre line mode (see
figure D)", page ??). If the rotary laser is in the
vertical position, only alignment to the Y-axis
is possible.
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. 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.
To start center line mode for the X-axis, press
the button for center line mode (17); to start
this for the Y-axis, press the button for center
line mode (17) together with the Y-axis but-
ton (15). Should the laser beam be aligned to
both axes at the same time, center line mode
must be started separately on each laser re-
ceiver.
Following the start of center line 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
receiver, the text display (e) shows XOK (X-ax-
is) or YOK (Y-axis) along with the center line
indicator (h). The value of the incline that is
found is displayed on the rotary laser. Center
line mode then ends automatically.
To cancel the centre line mode, press and
hold the centre line mode button (17).
If the laser beam was unable to find the cen-
ter line of the laser receiver within the pivot-
ing range, ERR appears in the text display (e)
and all LED direction indicators light up.
Press any button on the rotary laser or laser
receiver to cancel center line mode. Reposi-
tion the rotary laser and laser receiver so that
the laser receiver is situated within the pivot-
ing range of ±8.5% of the rotary laser. Ensure
that the laser receiver is aligned to the X-ax-
is or Y-axis so that the laser beam can pass
through the reception area (1) horizontally.
Then restart the function.
