Setting the unit of measure 
A) For measurements from the rear measuring tool edge,
weak backlighting and 25 °C operating temperature are ap-
plicable for high reflectivity of the target (e.g. a white-paint-
ed wall). In addition, a deviation influence of ± 0.05 mm/m
must be taken into account.
B) For measurements from the rear measuring tool edge,
strong backlighting and – 10 °C to +45 °C operating tem-
perature are applicable for low reflectivity of the target (e.g.
a black box). In addition, a deviation influence of
±0.15 mm/m must be taken into account.
C) The width of the laser line depends on the surface charac-
teristics and on the ambient conditions.
D) except battery compartment
The measuring tool can be clearly identified with the serial
number 5on the type plate.

Assembly
Inserting/Replacing the Batteries
Using alkali-manganese or rechargeable batteries is
recommended for operation of the measuring tool.
With 1.2-V-rechargeable batteries fewer measure-
ments could be possible than with 1.5-V-batteries.
To open the battery lid 3, press the latch 4and re-
move the battery lid. Insert the batteries/rechargea-
ble batteries. When inserting, pay attention to the
correct polarity according to the representation on
the inside of the battery compartment.
When the battery symbol appears for the first
time on the display, measurements are possible for
approx. another 15 minutes.
When the battery symbol flashes, the batteries/
rechargeable batteries must be replaced. Measure-
ments are no longer possible.
Always replace all batteries/rechargeable batteries at
the same time. Do not use different brands or types of
batteries/rechargeable batteries together.

Remove the batteries/rechargeable batteries
from the measuring tool when not using it for
longer periods. When storing for longer periods,
the batteries/rechargeable batteries can corrode
and self-discharge.
Operation
Initial Operation
Do not leave the switched-on measuring tool
unattended and switch the measuring tool off
after use. Other persons could be blinded by the
laser beam.
Protect the measuring tool against moisture
and direct sun light.
Do not subject the measuring tool to extreme
temperatures or variations in temperature. As
an example, do not leave it in vehicles for a long
time. In case of large variations in temperature,
allow the measuring tool to adjust to the ambient
temperature before putting it into operation. In
case of extreme temperatures or variations in tem-
perature, the accuracy of the measuring tool can
be impaired.

Avoid heavy impact to or falling down of the
measuring tool. After severe exterior effects to
the measuring tool, it is recommended to carry out
an accuracy check (see “Accuracy Check of the
Distance Measurement”, page 18) each time be-
fore continuing to work.
Switching On and Off
To switch on the measuring tool, briefly press the
measuring button 2. Measuring tool and laser are
switched on.
Do not leave the switched-on measuring tool
unattended and switch the measuring tool off
after use. Other persons could be blinded by the
laser beam.

Briefly press the measuring button 2to initiate the
measurement. Then the laser beam is switched off. To
switch the laser beam on again, briefly press the
measuring button 2. To initiate a further measure-
ment, briefly press the measuring button 2again.
Do not point the laser beam at persons or ani-
mals and do not look into the laser beam your-
self, not even from a large distance.
Note: The measured value typically appears within
0.5 seconds and no later than 4 seconds. The dura-
tion of the measurement depends on the distance,
the lighting conditions and the reflective properties of
the target surface. Upon completion of the measure-
ment the laser beam is automatically switched off.
Auto-Sum (see figure B)
The auto-sum automatically shows the sum of all indi-
vidual measurements (e.g. useful for the material cal-
culation).
The auto-sum value is erased as soon as the device is
switched off or if it automatically switches off whenno
button is pressed after 5 minutes.
The auto-sum is not saved. A subsequent correction
of the auto-sum is not possible.
Aim the laser beam at the target surface.

dimmed after approx. 10 seconds to preserve the
batteries/rechargeable batteries. When no button is
pressed for after approx. 30 seconds, the display illu-
mination goes out.
Working Advice
General Information
The reception lens 7and the laser beam outlet 8must
not be covered when taking a measurement.
The measuring tool must not be moved while taking a
measurement. 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 on the lighting condi-
tions and the reflective properties of the target sur-
face. For better visibility of the laser beam in extrane-
ous light, use the laser viewing glasses 10
(accessories) and the laser target plate 9(accesso-
ries) or shade the target area.

1 609 92A 3MW | (21.11.16) Bosch Power Tools
Influence Effects on the Measuring Result
Due to physical effects, faulty measurements cannot
be excluded 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 9(accessory) on
these surfaces.
Furthermore, faulty measurements are also possible
when sighting inclined target surfaces.
Also, air layers with varying temperatures or indirect-
ly received reflections can affect the measured value.
Accuracy Check of the Distance Measurement
The accuracy of the measuring tool can be checked as
follows:
– Select a permanently unchangeable measuring
section with a length of approx. 3 to 10 metres; its
length must be precisely known (e.g. the width of
a room or a door opening). The measurement
should be carried out under favourable conditions,
meaning, the measuring distance must be indoors
and the target surface for the measurement must
be smooth and reflect well.

English | 19
Bosch Power Tools 1 609 92A 3MW | (21.11.16)
– Measure the distance 10 times in succession.
The deviation of the individual measurements from
the average value must not exceed ±4 mm over the
entire measuring section in favourable conditions.
Record the measurements in order to be able to com-
pare the accuracy at a later date.
