Product Manual

Laser Setup
Position the laser at the manhole invert or on bottom of the trench at the desired elevation.
Turning On/Off the laser
Press the power button to turn On the laser; the LCD shows Initialization for one second (red and green
LEDs are on - diagnostic mode).
The unit starts the temperature/reference check while the thermometer/CAL symbol is flashing.
Don‘t start automatic functions at the menu before the reference check has been finished.
If an automatic function will be selected and then confirmed with the E button during the reference
check, the display shows the reference check is still running.
The standard display turns on and the self-leveling will start at once.
The unit is leveled when the laser beam is no longer flashing (once every second).
To turn Off the laser, press and hold the power button for two seconds.
If the laser is positioned beyond its self-leveling range of -12 to + 40%, the laser beam remains flashing.
Reposition the laser within its self-leveling range. The laser’s cross axis is completely compensated over
the entire roll range (+/- 15°). Once leveled, the unit constantly monitors its level condition. Depending on
the selection at settings, the setup control (Line alert) is activated 5 minutes or 30 seconds after self-
leveling was performed. If Line Alert condition comes Off, the beam (+LEDs) flashes
two times, pauses for 2 seconds and flashes again two times. After deleting the
Line Alert by pressing the E button, check the beam’s correct position using the target
at the last pipe which was led before the Line alert came off.
