down (35) slope button on the remote control until the re-
quired position is reached.
Automatic downwards plumb point function in the
vertical position
To align the measuring tool against a reference point on the
ground when it is in the vertical position, the variable laser
beam (8) can be turned downwards to be used as a plumb
point. The plumb point function can only be started via re-
mote control or the Bosch Levelling Remote App app.
The variable laser beam plumb point is not self-levelling.
Therefore, ensure that the measuring tool is levelled in when
starting the plumb point function.
To start the downwards plumb point
function, press the plumb point func-
tion button (25) on the remote con-
trol. The plumb point function symbol
will appear on the display while the
variable laser beam is aligned vertic-
ally. After it has been successfully
aligned, the plumb point function indicator (e) will appear on
the start screen.

Automatic Levelling

Overview

After switching on, the measuring tool checks the horizontal
and vertical position and automatically levels out any un-
evenness within the self-levelling range of approx. ±8.5 %
(±5°).
The symbol for levelling flashes on the
display during levelling. The status
indicator (12) on the measuring tool
and the status indicator for the re-
spective axis ((34) or (33)) on the re-
mote control flash green at the same
time.
The rotation is stopped until levelling has been completed
and the laser beams are flashing. The start screen will ap-
pear after levelling has been successfully completed. The
laser beams will light up continuously and rotation will start.
The status indicator (12) on the measuring tool and the
status indicator for the levelled axis ((34) or (33)) on the re-
mote control will light up green continuously.
If the measuring tool is at a slant of
more than 8.5 % or is positioned dif-
ferently to the horizontal or vertical
position, levelling will no longer be
possible. An error message will appear on the display and
the status indicator (12) will flash red.
Reposition the measuring tool and wait for it to re-level.
If the maximum levelling time is ex-
ceeded, levelling will be discontinued
with an error message.
Reposition the measuring tool and briefly press the on/off
button (11) to restart levelling.

Position changes

When the measuring tool is levelled in, it continuously
checks the horizontal and vertical position. Re-levelling is
automatically performed if there are any position changes.
Minimal position changes are levelled out without inter-
rupting the operation. This automatically compensates sub-
soil ground vibrations or weather influences.
For larger position changes, the rotation of the laser beam
will be stopped in order to avoid faulty measurements during
the levelling process and the laser beams will flash. The lev-
elling symbol appears on the display. The shock-warning
function will be actuated, if required.
The measuring tool will automatically detect the horizontal or
vertical position. To change between the horizontal and
the vertical position, switch the measuring tool off, reposi-
tion it and switch it on again.
If the position is changed without
switching on/off, an error message
will appear and the status
indicator (12) will flash red quickly.
Briefly press the on/off button (11) to
restart levelling.

Shock-warning function

The measuring tool has a shock-warning function. After posi-
tion changes or shock to the measuring tool, or in case of
ground vibrations, it keeps the measuring tool from levelling
in at changed positions, and thus prevents errors caused by
a change in the measuring tool's position.
GRL 650 CHVG: The shock-warning function operates at two
sensitivity levels. After the measuring tool is switched on,
the setting defaults to high sensitivity.
To activate shock warning:
The shock-warning function is
switched on by default. It is activated
approximately 30 s after the measur-
ing tool has been switched on.
During activation, the shock-warning
function indicator (c) will flash on the
display. The indicator lights up con-
tinuously after activation.
Shock warning actuated:
If the position of the measuring tool is
changed or a severe knock is re-
gistered, the shock warning will be ac-
tuated. The laser will stop rotating and
an error message will appear. The
status indicator (12) will quickly flash
red and a warning signal will sound at
a fast rate.
Confirm the warning message with
button (14) on the measuring tool or the slope button (31)
on the remote control. When working with automatic level-
ling (including slope operation), levelling is automatically re-
started.
