The serial number(14) on the type plate is used to clearly identify your measuring tool. u The accuracy and detection depth of the measuring result may be negatively af- fected if the condition of the substrate is unfavorable. Assembly Inserting/Changing the Battery It is recommended that you use alkaline manganese batteries to operate the measuring tool. To open the battery compartment cover(15), push the locking mechanism(16) in the direction of the arrow and lift the battery compartment cover. Insert the battery. When inserting the batteries, ensure that the polarity is correct according to the illustra- tion on the inside of the battery compartment. u Take the battery out of the measuring tool if you do not intend to use the tool for a long time. When it is stored in the measuring tool for longer periods, the battery can corrode and discharge itself. Battery indicator The battery indicator(h) on the display always indicates the current battery status: Display Capacity 60−100% 30−60% 5−30% 0−5% 1 609 92A 7LE | (07.04.2022) Bosch Power ToolsEnglish | 23 Operation 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. In case of large variations in temperature, leave the measuring tool to adjust to the ambient temperature before switching it on. The accuracy of the measuring tool and the functionality of the display may be compromised if exposed to extreme temperatures or variations in temperature. u Avoid hard knocks to the measuring tool or dropping it. After severe external influ- ences and in the event of abnormalities in the functionality, you should have the measuring tool checked by an authorised Bosch after-sales service agent. u Certain ambient conditions fundamentally impair the measuring results. These include, e.g. the proximity of devices that generate strong electric, magnetic or electromagnetic fields, moisture, metal building materials, foil-laminated insula- tion materials or conductive wallpaper or tiles. Therefore, also refer to other in- formation sources (e.g. construction plans) before drilling, sawing or routing into walls, ceilings or floors. u Hold the measuring tool by the intended gripping surface (8) only, so as not to influence the measurement. u Do not attach any stickers or labels to the sensor area(13) on the rear of the measuring tool. Metal labels in particular will affect measuring results. Do not wear gloves when taking measurements and make sure that you are properly earthed. If you are not properly earthed, the identification of live wires may be impaired. When taking measurements, avoid devices that emit strong elec- tric, magnetic or electromagnetic fields. If possible, deactivate all tools whose radiation could interfere with the measurement and switch off the corresponding functions or tools. Starting Operation Switching on/off u Before switching on the measuring tool, ensure that the sensor area(13) is dry. If necessary, use a cloth to dry the measuring tool. u If the measuring tool has been exposed to a significant change in temperature, leave it to adjust to the ambient temperature before switching it on. To switch on the measuring tool, press the on/off button(5). Bosch Power Tools 1 609 92A 7LE | (07.04.2022)24 | English To switch off the measuring tool, press the on/off button(5) again. If no button on the measuring tool is pressed for approx. 5mins, and no objects are de- tected, the measuring tool will automatically switch itself off to preserve battery life. Switching the display illumination on and off The display illumination can be switched on or off with the display illumination button(6). Switching audio signal on/off The audio signal can be switched on/off with the audio signal button(7). When the audio signal is switched off, the audio signal indicator(a) appears on the display. How it works (seefigureB) The measuring tool checks the base material of the sensor area(13) in the measurement direction A up to the maximum detection depth. Objects that are different from the ma- terial of the wall are detected. Move the measuring tool in a straight line in direction B over the wall. Always move the measuring tool over the base material applying light pressure, without lifting it off or changing the pressure. During the measurement, the contact pads(12) must always remain in contact with the surface. Measuring process Place the measuring tool on the surface to be examined and move it in direction B. – When the measuring tool approaches an object, the amplitude in the measuring indicator(i) increases and the light-up ring(1) lights up yellow. – The amplitude decreases when the measuring tool moves away from the object. – Above the centre of an object, the measuring indicator will indicate maximum amp- litude; the light-up ring(1) will light up red and an audio signal will sound. For small or deep-lying objects, the light-up ring(1) can continue to light up yellow without the audio signal sounding. u Wide objects are not indicated by the light-up ring or the audio signal throughout their complete width. In order to locate an object more precisely, move the measuring tool repeatedly (3×) back and forth over the object. The fine scale(j) is activated automatically in all operat- ing modes. The fine scale indicates a full amplitude when the object is below the centre of the sensor or when the maximum amplitude of the measuring indicator(i) is reached. In Drywall and Metal operating modes, the object centre indicatorCENTER(k) also lights up. 1 609 92A 7LE | (07.04.2022) Bosch Power ToolsEnglish | 25 Wider objects in the base material can be identified by a continuous high amplitude of the measuring indicator(i) and fine scale (j). The light-up ring(1) will light up yellow. The duration of the high amplitude corresponds approximately with the object width. If very small or deep-lying objects are being sought and the measuring indicator(i) reacts only slightly, move the measuring tool repeatedly over the object in a horizontal and ver- tical direction. Pay attention to the amplitude of the fine scale(j) and, when in Drywall and Metal operating modes, to the object centre indicator CENTER(k) as well, which will then allow for precise detection. u Before drilling, sawing or routing into walls, refer to other sources of informa- tion to ensure that you eliminate hazards. As the measuring results can be influ- enced through ambient conditions or the nature of the wall, there may be a hazard even though the measuring indicator(i) does not indicate an object in the sensor area, no audio signal sounds and the light-up ring(1) lights up green. Operating Modes You can achieve the best possible measuring results by selecting the correct operating mode. You can achieve the maximum detection depth for metal objects in the Metal op- erating mode. You can achieve the maximum detection depth for live wires in the Power cable operating mode. The selected operating mode is always shown by the green operating mode indicator(4). Drywall operating mode Drywall operating mode is designed for detecting wooden and metal objects in dry walls. To activate Drywall operating mode, press the Drywall operating mode button(11). The operating mode indicator(4) above the Drywall operating mode button will light up green. As soon the measuring tool is positioned on the surface to be examined, the light-up ring(1) will light up green, indicating readiness to measure. In Drywall operating mode, all available objects will be detected and displayed: (c) Non-metallic, e.g. wooden beams (d) Non-magnetic, but metal, e.g. copper pipe (e) Magnetic, e.g. reinforcing steel (f) Live, e.g. power lines Note: In the Drywall operating mode, other objects, e.g.water-filled plastic pipes, will be also displayed in addition to wooden and metal objects and live wires. For these objects, the Non-metallic object indicator(c) will appear in the display. Bosch Power Tools 1 609 92A 7LE | (07.04.2022)26 | English Nails and screws in the base material may result in wooden beams being identified as metal objects. If the display indicates a continuously high amplitude of the measuring indicator(i) and the fine scale(j), re-start the measuring process again by placing the measuring tool elsewhere on the surface. If the light-up ring(1) does not indicate readiness to measure when positioned on the surface to be examined, the measuring tool has not been able to detect the base material correctly. – Press and hold the Drywall operating mode button(11) until the light-up ring(1) lights up green. Take the measurement as normal. If, after having completed this measurement, you want to start a new measuring pro- cess on another wall, briefly press the Drywall operating mode button(11) in order to reset the measuring tool. – In rare cases, the measuring tool is not able to detect the base material because the sensor area(13) on the rear side is dirty. Clean the measuring tool with a soft, dry cloth and re-start the measuring process. Metal operating mode Metal operating mode is particularly suited to detecting magnetic and non-magnetic ob- jects, regardless of the nature of the wall. To activate Metal operating mode, press the Metal operating mode button(10). The light-up ring(1) and the operating mode indicator(4) above the Metal operating mode button will light up green. If the measuring tool passes over a metal object (the light-up ring(1) will light up red), the type of metal will be shown in the display. For magnetic metals (e.g. iron) the Mag- netic metal indicator(e) will appear, for non-magnetic metals (e.g. copper) the Non- magnetic metal indicator(d) will appear. Note: For reinforcement steel mesh and reinforcements in the examined based material, an amplitude is indicated over the entire surface in the measuring indicator(i). For rein- forcement steel mesh, it is typical that the magnetic metal indicator(e) appears directly above the iron rods, whereas the non-magnetic metal indicator(d) will appear between the iron rods. Power cable operating mode Power cable operating mode is only suitable for detecting live wires (110−230V). To activate Power cable operating mode, press the Power cable operating mode button(9). The light-up ring(1) and the operating mode indicator(4) above the Power cable operating mode button will light up green. 1 609 92A 7LE | (07.04.2022) Bosch Power ToolsEnglish | 27 When a live wire is detected, the indicator for live wires(f) will appear on the display. Move the measuring tool over the surface again in order to locate the live wire more pre- cisely. After moving the measuring tool over the surface multiple times, the live wire can be detected very precisely. If the measuring tool is very close to the wire, the light-up ring(1) will flash red and the audio signal will sound at a faster rate. Notes: – Live wires are detected in every operating mode. – Live wires can be detected more easily when power consumers (e.g. lamps, appli- ances) are connected to the wire being sought and switched on. Switch off electricity consumers before drilling, sawing or milling into the wall. – In certain conditions (such as behind metal surfaces or behind surfaces with high water content), live wires cannot always be detected. The signal strength of a live wire depends on the position of the cable. Therefore, take further measurements in close proximity or use other information sources to check if a live wire is present. – You can detect non-live wires as metal objects in the Metal operating mode. Solid-wire cables are not detected (as opposed to stranded-wire cables). – Static electricity can cause wires to be detected inaccurately (e.g. over a large area) or prevent them from being detected at all. To improve the detection, place your free hand flat on the wall next to the measuring tool, in order to remove the static electri- city. Working Advice Marking objects If required, detected objects can be marked. Perform a measurement as usual. Once you have found the boundaries or the centre of an object, mark its position through the marking hole(2). Temperature monitoring The measuring tool features temperature monitoring, as an exact measurement is only possible as long as the temperature inside the measuring tool remains constant. If the temperature monitoring indicator(g) lights up, the measuring tool is outside of the operating temperature range, or has been subjected to large fluctuations in temperature. Switch the measuring tool off and allow it to adjust to the ambient temperature switching it back on. Bosch Power Tools 1 609 92A 7LE | (07.04.2022)28 | English Warning function If the warning indicator(b) lights up on the display and the operating mode indicator(4) above the Drywall operating mode button(11) flashes, you must re-start the measure- ment. Remove the measuring tool from the wall and place it elsewhere on the surface. If the warning indicator(b) flashes on the display, send the measuring tool in its protect- ive bag(19) to an authorised Bosch after-sales service centre. Recalibration If the measuring indicator(i) indicates a continuously high amplitude in the Metal operat- ing mode, even though there is no metal object near the measuring tool, the measuring tool can be manually recalibrated. – Ensure that the battery indicator(h) still shows a capacity of at least 1/3. – Switch the measuring tool off. – Remove all objects near the measuring tool that could be detected (including watches or metal rings). Hold the measuring tool up horizontally so that the rear side of the measuring tool is pointing towards the floor. Avoid bright light sources and prevent direct sunlight from shining on the rear side of the measuring tool, without covering this area. – Press the on/off button(5) and the audio signal button(7) simultaneously and hold both buttons until the light-up ring(1) lights up red. Then release both buttons. – If the calibration was successful, the measuring tool will start automatically after a few seconds and will be ready for operation again. Note: If the measuring tool does not start automatically, repeat the recalibration. If the measuring tool still does not start, send it in its protective bag(19) to an authorised Bosch after-sales service centre. Maintenance and Service Maintenance and Cleaning u Check the measuring tool before each use. If the measuring tool is visibly damaged or parts have become loose inside the measuring tool, safe function can no longer be ensured. Always keep the measuring tool clean and dry to ensure optimum, safe operation. Never immerse the measuring tool in water or other liquids. Wipe off any dirt using a dry, soft cloth. Do not use any detergents or solvents. Do not remove the contact pads(12) on the rear side of the measuring tool. 1 609 92A 7LE | (07.04.2022) Bosch Power ToolsEnglish | 29 Only store and transport the measuring tool in the protective bag provided. If the measuring tool needs to be repaired, send it off in the protective bag.

Do not dispose of measuring tools or batteries with household waste. Only for EU countries: According to the Directive 2012/19/EU on waste electrical and electronic equipment and its transposition into national law, measuring tools that are no longer usable, and, ac- cording to the Directive 2006/66/EC, defective or drained batteries must be collected separately and disposed of in an environmentally correct manner. If disposed incorrectly, waste electrical and electronic equipment may have harmful ef- fects on the environment and human health, due to the potential presence of hazardous substances. Only for United Kingdom: According to Waste Electrical and Electronic Equipment Regulations 2013 (2013/3113) and the Waste Batteries and Accumulators Regulations 2009 (2009/890), measuring tools that are no longer usable must be collected separately and disposed of in an environmentally friendly manner. Français Consignes de sécurité Prière de lire et de respecter l’ensemble des instructions. En cas de non-respect des présentes instructions, les fonctions de pro- tection de l’appareil de mesure risquent d’être altérées. BIEN CONSERVER LES PRÉSENTES INSTRUCTIONS. u Ne confiez la réparation de l’appareil de mesure qu’à un réparateur qualifié utili- sant uniquement des pièces de rechange d’origine. La sécurité de l’appareil de me- sure sera ainsi préservée. 1 609 92A 7LE | (07.04.2022) Bosch Power ToolsFrançais | 31 u Ne faites pas fonctionner l’appareil de mesure en atmosphère explosive, en pré- sence de liquides, gaz ou poussières inflammables. L’appareil de mesure peut pro- duire des étincelles susceptibles d’enflammer les poussières ou les vapeurs. u Du fait de sa conception, l’appareil de mesure ne peut pas garantir une sécurité absolue. Afin d’exclure tout danger, prenez certaines précautions avant d’effec- tuer des travaux de perçage, de sciage ou de fraisage dans les murs, plafonds ou sols en consultant d’autres sources d’information telles que les plans de construction, les photos de la phase de construction etc. Les conditions environ- nantes (humidité de l’air, etc.) ou la présence à proximité d’autres appareils élec- triques risquent d’altérer la précision de l’appareil de mesure. La structure ou l’état des murs (par ex. humidité, matériaux de construction métalliques, papiers peints conducteurs, matériaux isolants, carreaux) ainsi que le nombre, le type, la dimension et la position des objets peuvent fausser les résultats de mesure. u Veillez à une mise à la terre suffisante lors des mesures. Dans le cas d’une mise à la terre insuffisante (port de chaussures isolantes, mesure effectuée debout sur un es- cabeau, etc.), la détection des câbles électriques risque d’être altérée. u En présence de conduites de gaz dans le bâtiment, vérifiez après avoir effectué des travaux sur les murs, les plafonds ou les sols qu’aucune conduite de gaz n’a été endommagée. u La détection de câbles électriques est plus facile quand les consommateurs élec- triques (lampes, appareils) alimentés par les câbles à détecter sont mis sous tension pendant la mesure. Éteignez tous les consommateurs électriques et mettez hors tension les câbles électriques avant de percer, scier ou fraiser dans des murs, des plafonds ou des sols. Vérifiez au terme des travaux que les objets qui ont été fixés ne se trouvent pas sous tension. u Lors de la fixation d’objets sur des cloisons sèches, assurez-vous que la cloison et les éléments de fixation sont capables de supporter le poids de l’objet, parti- culièrement lors de la fixation sur une ossature.
