To switch off the measuring tool, slide the On/Off switch 2 to the "Off" position.
When switching off, the levelling unit is locked.
 Do not leave the switched-on measuring tool unattended and switch the mea-
suring tool off after use. Other persons could be blinded by the laser beam.
To save energy, only switch the measuring tool on when you are using it.
Operation Modes (see figure A–C)
The measuring tool has three operating modes between which you can switch at any
time:
Operating Mode
Cross-line operation (with automatic levelling): Generates a horizontal
and a vertical laser line.
Cross-line and plumb point operation (with automatic levelling): Gener-
ates a horizontal and two vertical laser lines and a downwards plumb
point. The device projects the two vertical laser lines at a right angle to
one another.
Cross-line operation (without automatic levelling): Generates a horizontal
and a vertical laser line.
After switching on, the measuring tool is in cross-line operating mode with automatic
levelling.
To change the operating mode, press the operating mode button 3 until the required
operating mode is displayed by the corresponding operating mode display 5 lighting
up.
Working with Automatic Levelling
Position the measuring tool on a level and firm support or mount it to the tripod 11.
Select one of the operating modes with automatic levelling.
After switching on, the levelling function automatically compensates irregularities
within the self-levelling range of ±4°. The levelling is finished as soon as the laser
beams do not move any more.
If automatic levelling is not possible, e.g. because the surface on which the measuring
tool stands deviates by more than 4° from the horizontal plane, the laser switches off.
If this is the case, set up the measuring tool in a level position and wait for the self-lev-
elling to take place.
In case of ground vibrations or position changes during operation, the measuring tool
is automatically levelled in again. To avoid errors, check the position of the horizontal
and vertical laser line with regard to the reference points upon re-levelling.
