Operating The Measuring Tool; Switching On And Off; Establishing A Connection To The Remote Control/Laser Receiver - Bosch GRL 600 CHV Professional Notice Originale

Take care, therefore, that the measuring tool is stable to
avoid interruptions to the operation caused by relevelling.

Operating the measuring tool

The main functions of the measuring tool are controlled by
the buttons on the measuring tool and the remote con-
trol (41). Additional functions are available via the remote
control (41), the laser receiver (42), or via the Bosch Level-
ling Remote App (see "Overview of control options for the
functions", page 49).
For the indicator on the measuring tool's display (15), the
following applies:
– The current settings for this function will be indicated
when a function button (e.g. the line operation but-
ton (5)) is pressed for the first time. The settings will be
changed the next time a function button is pressed.
– In the lower part of the display, softkey symbols (i) are
shown in various menus. The corresponding function
keys (softkeys) arranged around the display can be used
to execute the functions represented by the symbols (i)
(see figure B). Depending on the corresponding menu,
the symbols show the usable function buttons (e.g. the
rotational operation button in the rotational operation
menu (6)) or additional functions such as Next (
Back ( ) or Confirm ( ).
– The softkey symbols (i) also make it easy to recognise
whether the Slope button down/Button for clockwise ro-
tation (3) and Slope button up/Button for anticlockwise
rotation (4) buttons in the current menu are used to slope
downwards (▼) or slope upwards (▲) or to turn in a
clockwise ( ) or anticlockwise ( ) direction.
– The function menus or status messages can be exited at
any time by briefly pressing the on/off button (11). This
will save the last setting of the function menu.
– The display will automatically go back to the start screen
five seconds after the last press of a button.
– The display (15) will light up with every press of a button
or signal that reaches the measuring tool. The light will go
out approximately one minute after the last press of a but-
ton.
Tilting or rotation in various functions can be accelerated if
the respective tilting or rotation buttons on the measuring
tool or the remote control are held down for longer.
All functions are reset to their standard setting when the
measuring tool is switched off.

Switching On and Off

Note: After the first time the tool is started up and before be-
ginning work, you should always perform an accuracy check
(see "Accuracy Check of the Measuring Tool", page 44).
To switch on the measuring tool, press the on/off but-
ton (11). A start sequence will appear for a few seconds, fol-
lowed by the start screen. The measuring tool emits the vari-
able laser beam (8) and the upwards plumb point (10) from
the outlet apertures (9).
Do not direct the laser beam at persons or animals and
u
do not stare into the laser beam yourself (even from a
distance).
Bosch Power Tools
Levelling starts automatically and is shown
by the flashing symbol for levelling on the
display, the flashing laser beams and the
flashing status indicator (12) (see "Auto-
matic Levelling", page 42).
After levelling has successfully been com-
pleted, the start screen will appear, the laser
beams will light up continuously, rotation will
start and the status indicator will light up
green continuously.
Never leave the measuring tool unattended when
u
switched on, and ensure the measuring tool is
switched off after use. Others may be blinded by the
laser beam.
To switch off the measuring tool, press and
hold the on/off button (11) until the switch-
off symbol appears on the display.
If the maximum permitted operating temper-
ature of 50 °C is exceeded, a warning mes-
sage will appear for a few seconds and the
),
status indicator (12) will flash red.
The measuring tool will then shut down in order to protect
the laser diode. Once it has cooled down, the measuring tool
is operational again and can be switched back on.
Establishing a connection to the remote control/laser
receiver
In the default factory setting, the measuring tool and the re-
mote control (41) and the laser receiver (42) supplied are
already connected via Bluetooth®.
To establish a connection to the remote control, then press
the button for anticlockwise rotation (30) and the button for
clockwise rotation (37) on the remote control, both for 5 s
and at the same time. While the connection to the remote
control is being established, the status indicators (34) and
(35) on the remote control will alternately flash green.
To establish a connection to the laser receiver, press the X-
axis and Y-axis buttons on the laser receiver for 5 s at the
same time. To do this, consult the operating instructions for
the laser receiver.

the Bluetooth® button (7) until the
symbol for establishing a connec-
tion with the remote control/laser
receiver appears on the display.
It will be confirmed on the display
whether a connection has success-
fully been established to the remote
control or the laser receiver.
If the attempt to establish a connec-
tion to the remote control is suc-
cessful, the status indicators (34)
