Robert Bosch GmbH, Power Tools Division D-70745 Leinfelden-Echterdingen Leinfelden, 26.08.2013 Assembly Inserting/Replacing the Batteries Alkali-manganese batteries are recommended for the operation of the measuring tool. To open the battery lid 5, press on the latch 4 and fold the battery lid up. Insert the batteries. When inserting, pay attention to the correct polarity according to the representation on the inside of the battery compartment. If the measuring tool is not used for longer periods of time, remove the batteries. The batteries can corrode or self-discharge after pro- longed storage. Operation Initial Operation Protect the measuring tool against moisture and direct sun light. Do not subject the measuring tool to extreme temperatures or var- iations in temperature. As an example, do not leave it in vehicles for Henk Becker Executive Vice President Engineering Helmut Heinzelmann Head of Product Certification PT/ETM9 OBJ_BUCH-1913-002.book Page 17 Monday, September 23, 2013 12:33 PM18 | English 2 609 140 996 | (23.9.13) Bosch Power Tools long time. In case of large variations in temperature, allow the measur- ing tool to adjust to the ambient temperature before putting it into op- eration. In case of extreme temperatures or variations in temperature, the accuracy of the measuring tool can be impaired. Avoid heavy impact to or falling down of the measuring tool. Switching On and Off Before switching the measuring tool on, make sure that the sensor area 6 is not moist. If required, dry the measuring tool using a soft cloth. To switch on the measuring tool, slide the On/Off switch 3 downwards. After a short self-test, the tool is ready for use. The readiness of use is in- dicated when the signal LED 2 illuminates. If the signal LED 2 fails to illu- minate after switching on the tool, you must replace the batteries. To switch off the measuring tool, slide the On/Off switch 3 up- wards. When no measurements are carried out for approx. 10 minutes, the measuring tool switches off automatically in order to extend the service life of the batteries. Note: If the measuring tool has automatically switched off, then the On/Off switch 3 will still be in the “On” position. To switch the measuring tool back on, first slide the On/Off switch 3 into the position “Off” and then back into the position “On”. Operating Modes The measuring tool detects objects below the sensor area 6. Before drilling, sawing or routing into a wall, protect yourself against hazards by using other information sources. As the accura- cy and scanning depth of the measuring tool can be reduced due to en- vironmental conditions or the wall material, there is a risk that objects may be within the sensor range, even if the display does not indicate an object (the signal LED 2 illuminates green).

Position the measuring tool on/against the surface being detected and move it sideways. – If no metal object is visible in the base material, then the signal LED 2 continues to illuminate green and no signal tone sounds. – When the measuring tool comes closer to a metal object, the signal LED 2 first lights up yellow and changes to red the closer it comes to the metal object. As soon as the signal LED lights up red, a signal tone is also emit- ted, the pitch of which rises the closer it comes to the metal object. – Over a metal object, the signal LED 2 illuminates red and a signal tone is emitted at maximum pitch. Even with a yellow signal LED 2, a metal object may be located below the sensor area. Small or low-lying metal objects are located in the vicin- ity of the sensor or the wall material impairs the measurement results. After moving over the surface the first time, the posi- tion of the metal object is only roughly indicated. If you move the measuring tool over the metal object several times, the object detection will become increasingly precise. After moving over the metal object several times (without lifting the measuring tool from the base material), its position can be indicated very accu- rately: if the signal LED 2 illuminates red and the signal tone sounds, the metal object is below the sensor area. When the pitch of the signal tone is highest, the metal object is located below the centre of the sensor. Signal LED Explanation green no object detected yellow – metal object in the vicinity of the sensor – small or low-lying metal object within the sensor area or – impairment of the sensor due to unfa- vourable wall material red and continuous tone metal object detected in the sensor area red flashing (fast) and inter- mittent sound “live” wire/conductor detected OBJ_BUCH-1913-002.book Page 19 Monday, September 23, 2013 12:33 PM20 | English 2 609 140 996 | (23.9.13) Bosch Power Tools Scanning for “Live” Wires The measuring tool indicates wires, which carry voltage between 110 V and 240 V and a frequency corresponding to the widely used standard (AC with 50 or 60 Hz). Other wires (carrying DC, higher/lower frequency or voltage) as well as non-“live” wires/conductors cannot be found relia- bly, but are possibly indicated as metal objects. The detection for “live” wires/conductors takes place automatically with every measurement. When a “live” wire/conductor is detected, the signal LED 2 flashes red and an intermittent signal tone sounds with rapid tone sequence. Move the measuring tool repeatedly over the surface to locate the “live” wire/conductor more precisely. After moving over the surface several times, the position of the “live” wire/conductor can be indicated very accurately. “Live” wires/conductors can be detected more easily when power con- sumers (e.g. lamps, appliances) are connected to the wire being sought and switched on. Note: Always ensure that you hold the measuring tool firmly without gloves to enable a good grounding. Also ensure that ladders/scaffolding must be grounded. Avoid ladders/scaffolding whose supports have plas- tic caps underneath them. Do not wear insulating footwear. Under certain conditions (e.g. below metal surfaces or behind surfaces with high water content), “live” wires/conductors cannot be securely de- tected. When the signal LED 2 illuminates yellow or red over a larger area, then the material is screening-off electrically and the detection for “live” wires/conductors is not reliable. Working Advice Measuring values can be impaired through certain ambient condi- tions. These include, e.g., the proximity of other equipment that produce strong magnetic or electromagnetic fields, moisture, me- tallic building materials, foil-laminated insulation materials or conductive wallpaper or tiles. Therefore, please also observe other information sources (e.g. construction plans) before drilling, sawing or routing into walls, ceilings or floors. Note: Do not hold the device in the area of the sensor, so as not to affect the measurement. This achieves more accurate measurement results.

The outer edges of an object are indicated by the colour change of the signal LED 2 from yellow to red. The centre of the metal object can be determined by the pitch. Using a pen, mark the sought after location at the top and the side marker aids 1. Continuous Flashing Green/Yellow/Red If the signal LED 2 flashes alternately green, yellow and red, even when no metal object or no “live” cable is in the vicinity, the measuring device must be sent in for service. Maintenance and Service Manual Calibration If the signal LED 2 illuminates red or yellow, even when no metal is in the vicinity of the measuring tool, the tool must be recalibrated. – To do this, switch the measuring device on using the On/Off switch 3. – Remove a battery from the switched on measuring device. – While the battery is removed, switch the measuring device off using the On/Off switch 3. – Reinsert the batteries into the measuring device (pay attention to the polarity!) – Now remove all objects in the vicinity of the measuring device (includ- ing wrist watches or rings of metal) and hold the measuring tool up in the air. – Switch the measuring device on using the On/Off switch 3 and off again within 3 seconds. The signal LED 2 of the measuring device will flash red in slow succession during the 3 seconds to indicate that it is ready to calibrate. – Switch the measuring device back on within 0.5 seconds. The calibra- tion is initiated and takes about 6 seconds. The signal LED 2 will flash green for 6 seconds in quick succession, the calibration is being per- formed. Now the device is once more ready for operation and the sig- nal LED 2 illuminates solid green. Note: If the sequence of switching off then on again is not followed, no cal- ibration is performed. The signal LED 2 remains either yellow or red, even though no metal is located within the vicinity. In this case, repeat the cal- ibration.
