– Point operation: The measuring tool
generates a vertical laser point facing
upward and a vertical laser point facing
downward.
Use button 8 to switch between the individual
operating modes, see table on page 24.
All modes except for point operation can be
selected both with and without automatic
leveling.
Receiver Mode
Receiver mode must be activated to work with
the laser receiver 25, –regardless of which
operating mode is selected–.
In receiver mode the laser lines flash at very
high frequency, enabling them to be detected
by the laser receiver 25.
To switch on receiver mode, press button 6.
Indicator 7 will light up green.
When receiver mode is switched on, the
laser lines are less visible to the human eye.
For this reason, switch receiver mode off by
pressing button 6 again to work without a
laser receiver. Indicator 7 will extinguish.
Automatic Leveling
Working with Automatic Leveling
(see figures B1–E1)
After switching on, the leveling function
automatically compensates irregularities
within the self-leveling range of ±4°. The
measuring tool is leveled in as soon as the
laser lines no longer flash.
If the automatic leveling function 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
beams flash. In this case, bring the measuring
tool to the level position and wait for the self-
leveling to take place.
In case of ground vibrations or position
changes during operation, the measuring tool
is automatically leveled in again. To avoid
errors by moving the measuring tool, check
the position of the laser beams with regard to
the reference points upon re-leveling.
Position the measuring tool on a level, firm
support or attach it to the rotating mount 18.
For work with automatic leveling, slide the On/
Off switch 14 to position “On ”.
If the measuring tool is outside of the self-
leveling range, the laser lines and/or points
will flash quickly.
If you deactivate automatic leveling (On/Off
switch 14 to position “On ”), the measuring
tool will switch to cross-line operation.
