Ensure that the Bluetooth® interface is activated on your mobile device.
Press the(1) button to bring up the Bluetooth® menu and press the(1) button again (or
the (6) [+] button), to activate the Bluetooth® interface. If multiple active measuring
tools are found, select the appropriate measuring tool using the serial number. You can
find the serial number(11) on your measuring tool's type plate. The connection status
and the active connection(b) are displayed in the status bar(h) of the measuring tool.
Bosch applications are available to expand the range of functions. Depending on the
device, you can download these applications from the corresponding app stores.
Deactivating the Bluetooth® interface
Press the(1) button to bring up the Bluetooth® menu and press the(1) button again (or
the (3) [–] button), to deactivate the Bluetooth® interface.
Assembly
Inserting/changing the batteries
Using alkali-manganese or nickel metal hydride rechargeable batteries (especially at low
operating temperatures) is recommended for operation of the measuring tool.
With 1.2 V batteries, more measurements may be possible than with 1.5 V batteries, de-
pending on the capacity.
Press the locking mechanism (12) to open the battery compartment cover (13) and re-
move the battery compartment cover. Insert the batteries. When inserting, pay attention
to the correct polarity according to the representation on the inside of the battery com-
partment.
When the state of charge of the batteries or reusable batteries is low, a request to activ-
ate the battery saver mode will appear on the display. When the battery saver mode is
activated, the battery runtime will be extended and the battery symbol on the display will
have a yellow outline(see "“Settings” menu (see figure B)", page20).
When the empty battery symbol first appears on the display, only a limited number of
measurements is still possible. When the battery symbol is empty and flashes red, no fur-
ther measurements are possible. Replace the batteries or reusable batteries.
Always replace all the batteries at the same time. Only use batteries from the same man-
ufacturer and which have the same capacity.

uTake the batteries out of the measuring tool when you are not using it for a pro-
longed period of time. The batteries can corrode and self-discharge during pro-
longed storage.
Operation
Start-Up
uNever leave the measuring tool unattended when switched on, and ensure the
measuring tool is switched off after use. Others may be dazzled by the laser beam.
uProtect the measuring tool from moisture and direct sunlight.
uDo not expose the measuring tool to any extreme temperatures or variations in
temperature. For example, do not leave it in a car for extended periods of time. In
case of large variations in temperature, allow the measuring tool to adjust to the ambi-
ent temperature before putting it into operation. The precision of the measuring tool
may be compromised if exposed to extreme temperatures or variations in temperat-
ure.
uAvoid substantial knocks to the measuring tool and avoid dropping it. Always
carry out an accuracy check before continuing work if the measuring tool has been
subjected to severe external influences (see "Checking accuracy and calibrating the
grade measurement (see figureL)", page28) and (see "checking accuracy of the
distance measurement", page29).
uThe measuring tool is equipped with a wireless interface. Local operating restric-
tions, e.g. in aeroplanes or hospitals, must be observed.
Switching on/off
– To switch on the measuring tool and the laser, briefly press the measuring button(5)
[ ].
– To switch on the measuring tool without the laser, briefly press the on/off/back
button(8) [ ].
uDo not direct the laser beam at persons or animals and do not stare into the laser
beam yourself (even from a distance).
When switching on the measuring tool for the first time, you will be prompted to set your
preferred language for the display text.
To switch off the measuring tool, press and hold the on/off/back button(8) [ ].
The measured values and device settings in the memory are retained when you switch off
the measuring tool.

Measuring process
When switching on for the first time, the measuring tool will be in the length measure-
ment function. When switching on every subsequent time, the measuring tool will be in
the measuring function that was last used. For a different measuring function, press the
(2) [Func] button. Use the (6) [+] button or the (3) [–] button to select the required
measuring function Measuring Functions. Activate the measuring function with the (2)
[Func] button or with the measuring button(5) [ ].
There are three settings available for the reference level for measurement (see "Selecting
the reference level (see figureA)", page20).
Apply the measuring tool to the point at which you want to start the measurement (e.g.
wall).
Note: If the measuring tool has been switched on using the on/off/back button(8) [ ],
briefly press the measuring button(5) [ ] to switch the laser on.
To initiate the measurement, briefly press the measuring button(5) [ ]. The laser beam
will then switch off. For a further measurement, repeat this process.
uDo not direct the laser beam at persons or animals and do not stare into the laser
beam yourself (even from a distance).
Note: The measured value typically appears within half a second, and no later than ap-
proximately four seconds. The duration of the measurement depends on the distance,
the lighting conditions and the reflective properties of the target surface. Upon comple-
tion of the measurement, the laser beam will automatically switch off.
Selecting the reference level (see figureA)
You can choose between three different reference levels for the measurement:
– The rear edge of the measuring tool (e.g. when placing against walls)
– The front edge of the measuring tool (e.g. when measuring from a table edge)
– The centre of the thread(14) (e.g. for tripod measurements)
To select the reference level, press the (7) [ ] button. Then select the “Reference level”
setting with the measuring button(5) [ ] or the (2) [Func] button. Then use the (6) [+]
button or the (3) [–] button to select the required reference level. Every time the meas-
uring tool is switched on, the last selected reference level is preset.
“Settings” menu (see figure B)
Press the(7) [ ] button to access the “Settings” menu(j).
Use the (6) [+] button or the (3) [–] button to select the required setting and confirm
this by pressing the measuring button (5) [ ] or the (2) [Func] button.
