The out-of-level indicator 37 flashes dur-
ing the search for the centre line.
The indicators for centre line mode 42
light up continuously.
As soon as the laser beam hits the recep-
tion area 26, a beep sounds until the cen-
tre line is found.
The speed at which the rotation head moves will slow down as
soon as the laser beam hits the reception area 26.
When the centre line has been found, the measuring tool au-
tomatically switches off the centre line mode.
– To cancel centre line mode during the search,
press the centre line mode button 19.
or
– Simultaneously press the slope buttons 18 and
20 to activate automatic levelling.

Speeding Up Finding the Centre Line of the Laser Receiver

Searching for the centre line of the laser receiver always be-
gins with a right-hand movement of the rotation head. The di-
rection of the movement can be changed if the laser beam is
to the left of the centre line and not yet in the reception area
of the laser receiver.
– Press the centre line mode button 19 for approx.
2 s.
The rotation head is automatically moved to the
right.
– Press the slope button 20.
The rotation head is moved downwards.
Relative Height Display (see figure F)
The distance between the rotational plane
and the centre line is shown on the display
as an absolute value (in [mm] or [inch]).
See also "Setting the Display of the Units",
page46.

Working with the Laser Receiver

For outdoor use or longer distances indoors, use the laser re-
ceiver to find the laser beam.
– Place the laser receiver so that the laser beam can reach
the reception area 26.
RF Communication between Measuring Tool and Remote
Control/Laser Receivers
In its delivery condition, the laser receiver provided LR50
acts as a remote control for the measuring tool via a wireless
connection.
1 609 92A 4DX | (28.3.18)
– The RF communication indicator 33 is displayed
to indicate the remote control function on the la-
ser receiver.
Multiple laser receivers LR50 can be assigned to the measur-
ing tool.
– Switch off the measuring tool and the laser receiver.
– Dock the additional laser receiver in the charging/storage
station 6.
– Press the On/Off button 17.
– The RF communication indicator 33 is displayed
to indicate the remote control function on the la-
ser receiver.
– Remove the laser receiver from the charging/storage sta-
tion again. To switch on the measuring tool, you then have
to press the On/Off button 17 within 30 minutes.
Note: If multiple laser receivers have been assigned to a
measuring tool, then the last assigned laser receiver acts as
the remote control. The other laser receivers are then purely
laser receivers.
Settings such as measuring accuracy or audio signal can be
set individually for each laser receiver.
If the remote control/laser receiver is switched off, the meas-
uring tool switches off. All other laser receivers each have to
switch off separately.
If the R F communication is lost, the RF communica-
tion indicator 33 flashes and an audio signal
sounds.
This signals that warnings (e.g. theft, anti-drift, cal-
ibration) will not be shown and the measuring tool
will no longer be remote-controlled.
Note: Sleep mode of the measuring tool can be switched on
and off only by pressing the sleep mode button 21 on the re-
mote control/ laser receiver.

Setting the Audio Signal/Volume

The position of the laser beam on the reception area 26 can
be indicated via an audio signal.
You can choose between two volumes or switch off the audio
signal.
The default setting in the delivery condition is
[Normal audio signal].
– Press the audio signal/volume button 24 repeat-
edly until the desired setting is reached.
No indicator: audio signal off
Normal audio signal
Loud audio signal
The setting for audio signal/volume is saved when the tool is
switched off.
