Activating the Bluetooth® Interface for Data Transmission
to a Mobile Terminal/Device
To activate the Bluetooth® interface, press the measuring
tool's Bluetooth® button 13. Make sure that the Bluetooth® in-
terface on your mobile terminal/device is activated.
Special Bosch applications (apps) are available to extend the
functional range of the mobile terminal/device and for simpli-
fication of the data processing. Depending on terminal/de-
vice, these can be downloaded at the respective app stores:
After starting the Bosch application, the connection between
the mobile terminal/device and the measuring tool is estab-
lished. When several active measuring tools are found, select
the appropriate measuring tool. When only one active meas-
uring tool is found, the connection is automatically estab-
lished.
Note: When establishing the connection between the meas-
uring tool and the mobile terminal/device (e.g., smartphone,
tablet) the first time (pairing), the measuring tool's PIN code
may be requested. In this case, enter "0000".
The connection status and the active connection are indicat-
ed on the display 1 (l).
When a connection cannot be established within 5 minutes
after pressing the Bluetooth® button 13, the Bluetooth® fea-
ture automatically switches off to save the batteries/re-
chargeable batteries.
When operating the measuring tool in the measuring rail 27,
data transmission is not possible.
Deactivating the Bluetooth® Interface
To activate the Bluetooth® interface, press the Bluetooth®
button 13 or switch the measuring tool off.
When the Bluetooth® interface is deactivated or when the
Bluetooth® connection is interrupted (e.g., because of too
large distance or obstructions between the measuring tool
and the mobile terminal/device as well as electromagnetic
disturbances), Bluetooth® (l) is no longer indicated on the
display.
Data Transmission via USB Interface
Connect the measuring tool to your computer or notebook
with the micro USB cable. After starting the software on your
computer or notebook, a connection is established to the
measuring tool.
To download the current software and for further information,
please refer to the Bosch website at
www.bosch-pt.de.

Note: As soon as the measuring tool is connected to a com-
puter or notebook via the micro USB cable, the lithium ion
battery is charged. The charge duration varies depending on
the charging current.
To recharge the measuring tool as quickly as possible, use the
provided charger, see "Battery Charging".
Working Advice
 The measuring tool is equipped with a radio interface.
Local operating restrictions, e.g. in airplanes or hospi-
tals, are to be observed.
General Information
The reception lens 17 and the laser beam outlet 18 must not
be covered when taking a measurement.
The measuring tool must not be moved while taking a meas-
urement (with the exception of the continuous measurement
and grade measurement functions). Therefore, place the
measuring tool, as far as this is possible, against or on a firm
stop or supporting surface.
Influence Effects on the Measuring Range
The measuring range depends upon the light conditions and
the reflection properties of the target surface. For improved
visibility of the laser beam when working outdoors and when
the sunlight is intense, use the laser viewing glasses 30 (ac-
cessory) and the laser target plate 31 (accessory), or shade
off the target surface.
Influence Effects on the Measuring Result
Due to physical effects, faulty measurements cannot be ex-
cluded when measuring on different surfaces. Included here
are:
– Transparent surfaces (e.g., glass, water),
– Reflecting surfaces (e.g., polished metal, glass),
– Porous surfaces (e.g. insulation materials),
– Structured surfaces (e.g., roughcast, natural stone).
If required, use the laser target plate 31 (accessory) on these
surfaces.
Furthermore, faulty measurements are also possible when
sighting inclined target surfaces.
Also, air layers with varying temperatures or indirectly re-
ceived reflections can affect the measured value.
Accuracy Check and Calibration of the Grade Measure-
ment (see figure H)
Regularly check the accuracy of the grade measurement. This
is done by carrying out a reversal measurement. For this,
place the measuring tool on a table and measure the grade.
Turn the measuring tool by 180 ° and measure the grade
again. The difference of the indicated reading may not exceed
by more than 0.3 ° (max.).
In case of greater deviation, the measuring tool must be recal-
ibrated. For this, press and hold the grade measurement but-
ton 3. Follow the directions on the display.
After severe temperature changes and impact, we recom-
mend an accuracy check and, if required, to recalibrate the
measuring tool. After a temperature change, the measuring
tool must acclimate for a while before calibrating.
