Operating Modes; Automatic Levelling - Bosch GLL 3-80 C Professional Originalbetriebsanleitung

Deactivating the Signal Tone Function
The signal tone function is always activated once the meas-
uring tool is switched on.
To deactivate or activate the signal tone function, simultan-
eously press the laser mode button
mode button ( 5) and hold them down for at least 3 s.
Three short signal tones will sound as confirmation both
when the signal tone function is activated and deactivated.

Operating Modes

The measuring tool has several operating modes which you
can switch between at any time. These are for:
–
Generating a horizontal laser plane,
–
Generating a vertical laser plane,
–
Generating two vertical laser planes,
–
Generating a horizontal laser plane and two vertical laser
planes.
After you switch it on, the measuring tool generates a hori-
zontal laser plane. To change the operating mode, press the
( 7)
laser mode button .
All operating modes can be selected with both automatic lev-
elling or the pendulum lock.
Receiver Mode
Receiver mode must be activated when working with the
( 29)
laser receiver , regardless of which operating mode is
selected.
In receiver mode, the laser lines flash at a very high fre-
quency, enabling them to be detected by the laser receiver
( 29)
.
To switch on receiver mode, press the receiver mode button
( 5)
. The receiver mode indicator
When receiver mode is switched on, the laser lines are less
visible to the human eye. Therefore, switch receiver mode
off by pressing the receiver mode button
without a laser receiver. The receiver mode indicator
go out.

Automatic Levelling

Working with Automatic Levelling
Position the measuring tool on a level, firm surface or attach
( 25)
it to the universal holder or the tripod
For work with automatic levelling, slide the on/ off
( 16) On
switch to the " " position.
The automatic levelling function automatically compensates
irregularities within the self-levelling range of ±
ling is finished as soon as the laser lines stop moving.
If automatic levelling is not possible, e.g. because the sur-
face on which the measuring tool stands deviates by more
than 4° from the horizontal plane, the laser lines will begin to
flash quickly. If the signal tone function is activated, rapid
signal tones will sound.
Set up the measuring tool in a horizontal position and wait
for the self-levelling to take place. As soon as the measuring
tool is within the self-levelling range of ± 4°, the laser lines
will light up continuously and the signal tones will cease.

In case of ground vibrations or position changes during oper-
ation, the measuring tool is automatically levelled again.
Upon re-levelling, check the position of the horizontal or ver-
tical laser line with regard to the reference points to avoid er-
rors by moving the measuring tool.
Working with the Pendulum Lock
For work with the pendulum lock, slide the on/ off
( 16) On
switch to the " " position. The pendulum lock indic-
( 4)
ator lights up red and the laser lines continuously flash
slowly.
For work with the pendulum lock, the automatic levelling is
switched off. You can hold the measuring tool freely in your
hand or place it on a sloping surface. This means that the
laser lines are no longer levelled and no longer necessarily
run perpendicular to one another.
Remote control via the Bosch Levelling Remote
App
The measuring tool is equipped with a
which uses radio technology to enable remote control via a
smartphone with a interface.
Bluetooth®
The Bosch Levelling Remote App
quired to use this function. You can download this in the app
store for your terminal device (Apple App Store, Google Play
Store).
I nformation about the system requirements for a
connection can be found on the Bosch website at
www.bosch‑pt.com
When remote controlling via
Bluetooth®
ditions can cause time delays between the mobile terminal
device and the measuring tool.
Switching on Bluetooth®
To switch on , press the
Bluetooth®
Ensure that the interface is activated on your mo-
Bluetooth®
bile terminal device.
The connection between mobile end device and measuring
tool is established after the Bosch application has started. I f
multiple active measuring tools are found, select the appro-
priate measuring tool. A connection will be established auto-
matically if only one active measuring tool is found.
The connection is established as soon as the
dicator ( 8) lights up.
The ® connection may be interrupted if the dis-
Bluetooth
tance between the measuring tool and the mobile terminal
device is too great or is blocked, and if there are any sources
of electromagnetic interference. Should this occur, the
( 8)
® indicator will flash.
