CHARGING THE BATTERY
Connect the charger with the charging plug of the instrument and the
power source. If the charging LED is red the battery is being charged;
if the LED is green the battery is fully charged.
ATTENTION
The rechargeable battery can be charged if it is in the instrument or if
it is ouside.
Battery status indication: If the ON/OFF LED flashes the battery has
to be recharged.
Both the standard Li-Ion battery pack and alkaline batteries can
be used.
1) Insert alkaline batteries into the alkaline battery box (ensure
correct polarity) and fix the battery box into the instrument.
OR
2) Fix the rechargeable battery box into the instrument.

OPERATION D
HORIZONTAL USE
Set up the instrument on an even surface or mount it onto a tripod.
After powering on the unit a flashing laser diode indicates that the automatic self-levelling procedure
is working. The laser starts rotating when self-levelled. If not the laser was set up outside of its self-
levelling range. In this case set up the instrument on a more even surface.
VERTICAL USE
· Unfold the datum point on the integrated floor mount and set up the laser in its vertical (lay-down)
position.
· The laser automatically self-levels in this position.
· Set the ciruclar bubble as accurately as possible by using the two thumb screws. This ensures that
the instrument is set within its self-levelling range and the rotating beam is centered over its datum
point.

OPERATION - INSTRUMENT KEYPAD
POWER ON/OFF (2)
Power the laser on/off with button (2). If the red ON/
OFF LED (1) is illuminated the laser is powered on.
First the laser dot is flashing, then the self-levelling
procedure starts automatically; meanwhile the TILT
LED (8) is flashing. When the self-levelling procedure is
completed the laser rotates with 600 rpm and the TILT
LED (8) is illuminated permanently (= TILT function
activated).

If in normal use the ON/OFF LED (1) flashes the battery has to be recharged.
ROTATING SPEED (3)
The instrument standardly rotates with max. speed (= 800 rpm). Press button (3) to change to 300 rpm.
ON / OFF REMOTE CONTROL FUNCTION - INSTRUMENT BUTTON ONLY (4)
With this button the remote control function can be disabled in order to avoid that several units on one
construction site disturb each other. If the remote control LED is illuminated it is the remote control
function is ready-to-receive.
LED REMOTE CONTROL (9)
If the LED is illuminated the the remote control function is ready-to-receive.
TILT MODE (7)
After completion of the self-levelling procedure the TILT mode is automatically enabled.
If the level is now disturbed the rotation stops and the TILT LED is flashing.
1. Press theTILT button (7) once: The rotation of the laser starts - but the TILT mode is disabled.
2. Press theTILT button (7) twice: The rotation of the laser starts, the self-levelling procedure is
completed and the laser restarts working with enabled TILT mode.
Press button (7) to disable the TILT mode after completion of the self-levelling procedure.

RELATIVE 0-POSITION (REFERENCE POINT)
Within the range of ± 20 mm of the standard reference point (0-position) a relative 0-position can be
set. Press the „0SET“ button when the laser beam hits the receiving window (the „0SET“ symbol will
flash on the display). This current position of the laser beam is now set as the relative 0-position on the
receiver. Press the „0SET“ button to return to the default mode.
MM INDICATION
If the reference level of the receiver is e. g. 18 mm below the laser beam this height difference will be
displayed by an exact numerical value (see the left diagram).
further examples
The laser beam is
exactly on-level.
The laser beam is
19 mm above the
reference point
(move the receiver
up).
The laser beam is
35 mm below the
reference point
(move the receiver
