Safety Instructions

All instructions must be read and observed in order for the measuring tool to function safely. The safeguards integrated into the measuring tool may be compromised if
the measuring tool is not used in accordance with these instructions. Never make warning signs on the measuring tool unrecognizable. SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE AND INCLUDE THEM WITH THE MEASURING TOOL WHEN  RANSFERRING IT TO A THIRD PARTY.

• Warning! If operating or adjustment devices other than those specified here are used or other procedures are carried out, this can lead to dangerous exposure to radiation.
• The measuring tool is delivered with a laser warning sign (marked in the illustration of the measuring tool on the graphics page).
• If the text of the laser warning label is not in your national language, stick the provided warning label in your national language over it before operating for the first time.

Do not direct the laser beam at persons or animals and do not stare into the direct or reflected laser beam yourself. You could blind somebody. cause accidents or damage your eyes.

• If laser radiation hits your eye, you must close your eyes and immediately turn your head away from the beam.
• Do not make any modifications to the laser equipment.
• Do not use the laser goggles (accessory) as protective goggles. The laser goggles
  make the laser beam easier to see: they do not protect you against laser radiation.
• Do not use the laser goggles (accessory) as sunglasses or while driving. The laser goggles do not provide full UV protection and impair your ability to see
• Have the measuring tool serviced only by a qualified specialist using only original replacement parts. This will ensure that the safety of the measuring tool is main­
• Do not let children use the laser measuring tool unsupervised. They could uninten­tionally blind themselves or other persons.
• Do not use the measuring tool in explosive atmospheres which contain flammable liquids, gases or dust. Sparks may be produced inside the measuring which can ignite dust or fumes.
• The measuring tool is equipped with a wireless interface. Local operating restric­tions, e.g. in aeroplanes or hospitals, must be observed.

The Bluetooth word mark and logos are registered trademarks owned by Bluetooth SIG, Inc. and any use of such marks by Robert Bosch Power Tools GmbH is under li­cense.

• Caution! When using the measuring tool with Bluetooth’, a fault may occur in other devices and systems, aeroplanes and medical devices (e.g. pacemakers, hearing aids). Also, damage to people and animals in the immediate vicinity can­not be completely excluded. Do not use the measuring tool with Bluetooth in the vicinity of medical devices, petrol stations, chemical plants, areas with a poten­tially explosive atmosphere and in blasting areas. Do not use the measuring tool with Bluetooth on aeroplanes. Avoid using the product near your body for exten­ded
• Do not use the measuring tool if the touchscreen is visibly damaged (e.g. cracks in the surface etc.).

Technical data

A) When measuring from the front edge. In unfavourable conditions such as very strong lighting, a temperature greatly deviating from 25 °C or a poorly reflecting surface, the measuring range can be restricted.
B) In unfavourable conditions such as strong lighting, high altitudes or a poorly reflecting surface, the maximum deviation can be ±4 mm with a deviation of ±0.15 mm/m. In favourable conditions, a deviation of ±0.05 mm/m needs to be taken into account.
C) In continuous measurement mode, the max. operating temperature is +40 °C.
D) Only non-conductive deposits occur, whereby occasional temporary conductivity caused by condensation is expected.
E) Bluetooth® deactivated
F) When using Bluetooth® Low Energy devices, it may not be possible to establish a connection depending on the model and operating system.
Bluetooth® tools must support the GATT profile.
The serial number (6) on the type plate is used to clearly identify your measuring tool.

Inserting/Changing the Battery

Always replace all the non-rechargeable batteries at the same time. Only use nonrechargeable batteries from the same manufacturer and which have the same capacity.
When inserting the batteries, ensure that the polarity is correct according to the illustration on the inside of the battery compartment.
Take the non-rechargeable batteries out of the measuring tool if you are not using it for a long time. The non-rechargeable batteries can corrode and self-discharge during prolonged storage.

Operation

Using the touchscreen
Do not use the measuring tool if the touchscreen is visibly damaged (e.g. cracks in the surface etc.).

• The display divides into the fields of the status bar (A) and touch-screen (B) with the menu bar (C).
• The status bar (A) shows the Bluetooth® connection status, temperature warning and the state of charge of the non-re-chargeable batteries/rechargeable batteries.
• The measuring tool can be controlled by touching the buttons using the touchscreen (B).
• The menu bar (C) holds additional functions (e.g. Bluetooth® on/off, menu, delete).
• Use only your fingers to operate the touchscreen. Lightly tap the relevant button (control). Do not tap the touchscreen with high pressure or sharp objects.
• Do not bring the touchscreen into contact with other electrical devices or water.
• To clean the touchscreen, switch the measuring tool off and wipe off dirt with a microfibre cloth, for instance.

Start-Up

• Never leaves 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.
• Protect the measuring tool from moisture and direct sunlight.
• 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 ambient temperature before putting it into operation. The precision of the measuring tool may be compromised if exposed to extreme temperatures or variations in temperature.
• Avoid substantial knocks to the measuring tool and avoid dropping it. After strong external influences on the measuring tool, you should always carry out an accuracy check (see “Accuracy Check”, page 25) before further work. Switching On and Off
• Press the A button to switch the measuring tool and the laser on.
• Press and hold the button to switch off the measuring tool.
• If no button on the measuring tool is pressed for approx. 5 min, the measuring tool will switch off automatically to preserve the non-rechargeable batteries. All stored values are retained when the tool is switched off.

Measuring Process

Once switched on, the measuring tool is in the length measurement function.
Once the measuring tool has been switched on, the rear edge of the measuring tool is selected as the reference level for measurement. You can change the reference level.
“Selecting the Reference (see Level”, page 22)

• Apply the measuring tool to the point at which you want to start the measurement (e.g. wall).
• Press the button to switch on the laser beam.
• Target the target surface with the laser beam.
• Briefly press the   button. button again to start the measurement.
• In the continuous measurement function, the measurement begins immediately after the first press of the button.

The reception lens (9) and the laser beam output (8) must not be covered during the measuring process.
Selecting the Reference Level
For the measurement, you can select from various reference levels:
The rear edge of the measuring tool (e.g. when placed against walls)

The tip of the stop plate (3) folded by 180° (e.g. for measurements from corners)
The front edge of the measuring tool (e.g. when measuring from a table edge)
