Getting started
Right: pendulum lock
This instrument is a precision instrument that must be
handled with care. When not in use, the pendulum should
always be in the "OFF" position. Locking the pendulum allows
the instrument to better withstand vibration and prevent
possible damage during transport or because of a fall.
Left: automatic leveling
When the pendulum is unlocked "ON", it can be
automatically leveled. For the self-leveling function to work,
the tilt of the instrument housing must not exceed 3.5°.

Additional functions
When the device is in the pendulum lock mode (switch
on the right side), it is possible to select the alignment lock
mode by pressing and holding the line selection button for 3
seconds. The device turns on the laser beams in this mode,
but the pendulum is locked, and the accuracy is not aligned.
In this mode, the device can be used for some special tasks
such as leveling stairs. In this mode, the laser beam will ash
every 5 seconds. to indicate that self-leveling is off.
Light indication
Out of tilt alarm:
• when the pendulum is unlocked and the tilt of the device
does not exceed 3.5°, the device is in self-leveling mode
without any LED indication;
• when the tilt of the body exceeds 3.5°, the laser beam
starts to ash.
Low battery alarm
The green LED indicator turns on and starts blinking
slowly when the operating voltage is <4V. In this situation,
you need to replace the batteries with new ones.
