When the shock-warning function has actuated, briefly press
the on/off button (3). The shock-warning function is restar-
ted and the measuring tool starts the levelling. As soon as
the measuring tool is levelled (the X‑axis (7) and Y‑axis (6)
status indicators will light up continuously), it will start up in
the saved operating mode.
Now check the position of the laser beam at a reference
point and, if necessary, correct the height or alignment of
the measuring tool.
Switching off the shock-warning function: To switch the
shock-warning function off or on, briefly press the on/off
button (3) once or, when the shock warning has actuated
(shock-warning indicator (13) flashes red), twice. When the
shock-warning function is switched off, the shock-warning
indicator (13) will light up red continuously.
If the shock-warning function has been switched on, it will be
activated after approximately one minute.
Note: The shock-warning function cannot be switched on or
off or restarted with the remote control.

Tilting the axis: The slope of an axis in slope operation or
manual operation can be altered within five seconds of se-
lecting the axis (as long as the relevant status indicator of the
axis is flashing red). If the status indicator lights up red con-
tinuously, the slope has been determined. To alter the slope,
press the manual operation button (14) on the measuring
tool or the manual operation button (31) on the remote con-
trol again until the status indicator of the required axis
flashes red.

The automatic levelling of the measuring tool can be
switched off (manual operation):
– in the horizontal position for both axes independently of
each other,
– in the vertical position for the X‑axis (the Y‑axis cannot be
levelled in the vertical position).
It is possible to set up the measuring tool at any inclination in
manual operation mode. The axes can also be tilted inde-
pendently of each other in a range of ±8 % on the measuring
tool.
Selecting the axis: To start the manual operation or select
the axis to be tilted, press the manual operation button (14)
on the measuring tool or the manual operation button (31)
on the remote control. You can see on the X‑axis (7) or
Y‑axis (6) status indicators which axis is no longer level and
can be tilted.
