[Starting the operation]
Press the power supply key.
Automatic self-leveling function works and leveling begins
automatically. When leveling is completed, the rotor begins to rotate
and emits invisible laser beam.
NOTE:
• Before operating the instrument, perform the ‘Check and adjustment
of the datum point’ on page 35.
• Before operating the instrument, confirm that the manual mode display
lamp is not turned on in red. While automatic self-leveling function,
(the manual mode display lamp turns on in red) pay attention that
the horizontal accuracy of emitted laser beam is not guaranteed.
• When the status that the automatic self-leveling function is not stable
continues for about 3’, the off level display lamp turns on in red and
rotation of rotor and the emission of laser beam stop.
• While not in operation, be sure to turn the instrument’s power switch off.

• While the instrument is operating, be careful not to expose your
eyes to the emitting laser beam (red light source). Exposure to a
laser beam for a long time may be hazardous to your eyes.
