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 C)", page44). 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. u Take 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. Inserting/changing the lithium-ion battery pack (accessory) Insert the lithium-ion battery pack (24) (see figure A). To remove the lithium-ion battery pack (24), press the locking mechanism (25) and take the lithium-ion battery pack out. Bosch Power Tools 1 609 92A 4ZJ | (14.10.2020)42 | English Operation Charging the lithium-ion battery pack (accessory) Note: The battery is supplied partially charged. To ensure full capacity of the battery, completely charge the battery before the first use. The USB port for connecting the USB cable(26) and the charging indicator light can be found under the flap for the USB port(27) on the lithium-ion battery pack(24) (access- ory). Open the flap for the USB port(27) and connect the USB cable(26). During the charging process, the battery indicator on the display may differ from the ac- tual state of charge of the lithium-ion battery pack (24). When the lithium-ion battery pack (24) is fully charged, the charging indicator light will light up green. During charging, the charging indicator light lights up yellow. A red charging indicator light indicates that the charging voltage or charging current are unsuitable. Start-Up u Never 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. u Protect the measuring tool from moisture and direct sunlight. u Do 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. u Avoid 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 figureM)", page51) and (see "checking accuracy of the distance measurement", page51). u The 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) [ ]. 1 609 92A 4ZJ | (14.10.2020) Bosch Power ToolsEnglish | 43 u Do 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.

Activate the measuring func- tion 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 figureB)", page43). 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. u Do 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 figureB) 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) [+] Bosch Power Tools 1 609 92A 4ZJ | (14.10.2020)44 | English 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 C) Press the(7) [ ] button to access the “Settings” menu(j).

Continuous measurement In continuous measurement mode, the measuring tool can be moved relative to the tar- get, during which the measured value will be updated approx. every half a second. You can, for example, move a desired distance away from a wall while reading off the current distance at all times. Select continuous measurement . Select one of the following functions: – Min/max: The smallest and largest measured value are permanently shown on the dis- play (see figureJ). – Large numbers: The measured value is displayed in an enlarged format for better legibility (see figureK). – Tape measure: The distance will be displayed visually, as with a tape measure (see figureL). Note: The distance from the marking is shown in the display in the tape measure function. The reference is not the edge of the measuring tool. To switch on the laser beam, briefly press the measuring button (5)[ ]. Move the measuring tool until the required distance is shown at the bottom of the dis- play.

-64° Briefly pressing the measuring button(5) [ ] will interrupt the con- tinuous measurement. The current measured value will be shown at the bottom of the display. Pressing the measuring button(5) [ ] once more will start the continuous measurement again. Continuous measurement automatically switches off after four minutes. Area measurement Select the area measurement mode . Bosch Power Tools 1 609 92A 4ZJ | (14.10.2020)46 | English Then measure the width and length one after the other as with a length measurement. The laser beam remains switched on between the two measurements. The distance to be measured flashes in the indicator for area measurement .

The first measured value is shown at the top of the display. After the second measurement has been completed, the area will be automatically calculated and displayed. The end result is shown at the bottom of the display, while the individual measured values are shown above it. Volume measurement Select the volume measurement mode . Then measure the width, length and depth one after the other as with a length measure- ment. The laser beam remains switched on between the three measurements. The dis- tance to be measured flashes in the indicator for volume measurement . 1474.8 m

m10.160 The first measured value is shown at the top of the display. After the third measurement has been completed, the volume will be automatically calculated and displayed. The end result is shown at the bottom of the display, while the individual measured values are shown above it. Indirect distance measurement For indirect length measurements, three measuring modes are available. Each measur- ing function can be used for determining different distances. The indirect distance measurement is used to determine distances that cannot be meas- ured directly, due to an obstacle that would impede the path beam or the absence of a target surface that could serve as a reflector. This measuring procedure can only be em- ployed vertically. Any horizontal deviation will lead to measurement errors. Note: Indirect distance measurement is always less accurate than direct distance meas- urement. For application-related reasons, measuring errors can be greater than with dir- ect distance measurement. To improve the accuracy of measurement, we recommend the use of a tripod (accessory). The laser beam remains switched on between the individual measurements. a) Indirect height measurement (see figureE) Select the indirect height measurement mode . 1 609 92A 4ZJ | (14.10.2020) Bosch Power ToolsEnglish | 47 Ensure that the measuring tool is at the same height as the lower measuring point. Then tilt the measuring tool around the reference level and measure distance 1 as for a length measurement (displayed as a red line).

45° m20.000 45.0° Once the measurement is complete, the result for the required dis- tance X is displayed in the result line (e). The measured values for distance 1 and angle α can be found in the measured value rows (d). b) Double indirect height measurement (see figureF) The measuring tool can indirectly measure all distances that lie in the vertical level of the measuring tool. Select the double indirect height measurement mode . Measure distances 1 and 2 in succession as for a length measurement.

-10° m10.154 45.0° m12.208 Once the measurement is complete, the result for the required dis- tance X is displayed in the result row (e). The measured values for distances 1 and 2 and angle α can be found in the measured value rows (d). Ensure that the reference level for the measurement (e.g. the rear edge of the measuring tool) remains in exactly the same place for all the individual measurements in a single measuring process. c) Indirect length measurement (see figureG) Select the indirect length measurement mode . Ensure that the measuring tool is at the same height as the required measuring point. Then tilt the measuring tool around the reference level and measure distance 1 as for a length measurement.

60° m20.000 60.0° Once the measurement is complete, the result for the required dis- tance X is displayed in the result row (e). The measured values for distance 1 and angle α can be found in the measured value row (d). Wall area measurement (see figureH) The wall area measurement is used to determine the sum of multiple individual areas with a common height. In the illustrated example, the total area of several walls that have the same ceiling height H but different lengths L is to be determined. Select the wall area measurement mode . Bosch Power Tools 1 609 92A 4ZJ | (14.10.2020)48 | English Measure the ceiling height H as for a length measurement. The measured value is dis- played in the top measured-value line. The laser remains switched on.

Then measure the length L

of the first wall. The area is automatically calculated and displayed in the result line (e). The last measured value for length can be found in the bottom measured value line (d). The laser remains switched on. Now measure the length L

of the second wall. The individual meas- ured value displayed in the measured value line (d) is added to the length L

. The sum of the two lengths (displayed in the middle measured value line (d)) is multiplied by the saved height H. The total area value is displayed in the result line (e). You can measure any number of lengths L

, which will be automatically added and multi- plied by the height H. The requirement for a correct area calculation is that the first measured length (for example the ceiling height H) is identical for all sub-areas. Stake out function (see figureI) The stake out function repeatedly measures a defined length (distance). These lengths can be transferred to a surface, for example to enable material to be cut into pieces of equal lengths or to install stud walls in a drywall construction. The minimum adjustable length is 0.1 m and the maximum length is 50 m. Note: The distance from the marking is shown in the display in the stake out function. The reference is not the edge of the measuring tool. Select the stake out function . Use the button (6) [+] or the button (3) [–] to set the required length. Begin the stake out function by pressing the measuring button (5) [ ] and slowly move away from the starting point. m2.800 0.200m14x The measuring tool continuously measures the distance to the start- ing point. The defined length and the current measured value are thereby displayed. The lower or upper arrow displays the shortest distance to the next or last marking. 14 x

0.200m14.44x The left factor specifies how many times the defined length has already been reached. A green measured value indicates that a length has been reached for marking purposes. A blue measured value indicates the actual value when the reference value is outside the display. 1 609 92A 4ZJ | (14.10.2020) Bosch Power ToolsEnglish | 49 Grade measurement/digital spirit level Select the inclination measurement/digital spirit level . The measuring tool automatically switches between two states. 1°2° 3° The digital spirit level is used to check the horizontal or vertical align- ment of an object (e.g. washing machine, refrigerator, etc.). When the inclination exceeds 3°, the ball in the display lights up red. 30.0° Grade measurement is used to measure a slope or incline (e.g. of stairs, railings, when fitting furniture, laying pipes, etc.). The left-hand side of the measuring tool serves as the reference level for grade measurement. Memory value display The value or end result of each completed measurement is automatically saved. Maximum 30values (measured values or end results) can be retrieved. Select the memory function [ ].

The number of the memory value is shown at the top of the display, the corresponding memory value is shown at the bottom and the cor- responding measuring function is shown on the left. Press the [+] button(6) to browse forwards through the saved val- ues. Press the [–] button(3) to browse backwards through the saved val- ues. The oldest value is located in position 1 in the memory, while the newest value is in posi- tion 30 (when 30 memory values are available). If a further value is saved, the oldest value in the memory is always deleted. Deleting the memory To delete an individual memory value, select this value(see "Memory value display", page49). To delete, first press the on/off/back button (8) [ ] and confirm this by pressing the (2) [Func] button. To delete all the contents of the memory, press the (7) [ ] button and select the function.
