• Do not operate the measuring tool in explosive environments, such as in the presence of flammable liquids, gases or dust. Sparks can be created in the measuring tool which may ignite the dust or fumes.
• For technological reasons, the measuring tool cannot ensure 100 % certainty. To rule out hazards, safeguard yourself each time before drilling, sawing or routing in walls, ceilings, or floors by means of other information sources, such as building plans, pictures from the construction phase, etc. Environmental influences, such as humidity or closeness to electrical devices, can influence the accuracy of the measuring tool. Surface quality and condition of the walls (e.g., moisture, metallic building materials, conductive wallpaper, insulation materials, tiles), as well as the amount, type, size, and position of the objects, can lead to faulty measuring results.

Battery tool use and care

• Recharge only with the charger specified by the manufacturer. A charger that is suitable for one type of battery pack may create a risk of fire when used with another battery
  pack.

• Use power tools only with specifically designated battery packs. The use of any other battery packs may create a risk of injury and fire.

• When the battery pack is not in use, keep it away from other metal objects, like paper clips, coins, keys, nails, screws or other small metal objects, that can make a connection from one terminal to another. Shorting the battery terminals together may cause burns or a fire.

• Under abusive conditions, liquid may be ejected from the battery; avoid contact. If contact accidentally occurs, flush with water. If liquid contacts the eyes, additionally seek medical help. Liquid ejected from the battery may cause irritation or burns.

• Do not open the battery pack. The danger of short-circuiting. Protect the battery pack against heat, e.g., against continuous intense sunlight, fire, water, and moisture. The danger of explosion.

• In case of damage and improper use of the battery pack, vapors may be emitted. Provide fresh air and seek medical help in case of complaints. The vapors can irritate the respiratory system.

• Use the battery only in conjunction with your Bosch product. This measure alone protects the battery against dangerous overload.

• The battery can be damaged by pointed objects such as nails or screwdrivers or by force applied externally. An internal short circuit can occur and the battery can burn, smoke, explode or overheat.

Operation

• Protect the measuring tool against moisture and direct sunlight.
• Do not subject the measuring tool to extreme temperatures or variations in temperature. As an example, do not leave it in vehicles for longer periods. In case of large variations in temperature, allow the measuring tool to adjust to the ambient temperature before putting it into operation.
• Hold the measuring tool at the intended grip area 10 only, so as not to influence the measurement.
• The use or operation of transmitting systems, such as WLAN, UMTS, radar, transmitter masts, or microwaves, in close proximity, can influence the measuring function.
• The measuring values can be impaired through certain ambient conditions. These include, e.g. the proximity of devices that produce strong electric, magnetic or electromagnetic fields, moisture, metallic building materials, foil-laminated insulation materials, or conductive wallpaper or tiles. Therefore, also observe other information sources (e.g. construction plans) before drilling, sawing, or routing into walls, ceilings, or floors.

Initial Operation

Switching On and Off
Check the measuring tool before each use. In the following cases, the safe function can no longer be ensured:
– The measuring indicator h constantly deflects, even though you hold the tool in the air.
–The measuring indicator does not deflect, even though you keep a finger in the sensor area.
– The device has visible damage or loose components inside the measuring tool.
– Safe function is ensured only when one of the operating mode selector buttons lights up.

• Before switching the measuring tool on, make sure that the sensor area 14 is not moist. If required, dry the measuring tool using a soft cloth.
• If the measuring tool was subject to an extreme temperature change, allow it to adjust to the ambient temperature before switching on. To switch on the measuring tool, press the On/Off button 6 .
  To switch off the measuring tool, press the On/Off button 6 again.
  When no button on the measuring tool is pressed for approx. 5 minutes and when no objects are detected, the measuring tool automatically switches off to save the battery.

Switching the Audio Signal On/Off
The audio signal can be switched on/off with the audio signal button 5 . When the audio signal is switched off, display 3 indicates the information c.

Method of Operation (see figure B)
The measuring tool checks the base material of the sensor area 14 in measurement direction A. Objects are detected that differs from the material of the wall. Always move the measuring tool over the base material applying light pressure, without lifting it off or changing the pressure. The measuring tool can be moved in any direction B.

Operation Modes
As soon as the measuring tool is switched on, you can switch between different operating modes.
By selecting the operating modes, you can adjust the measuring tool to different wall materials and, if required, suppress unwanted objects.
If the wall material is not known, you should begin with the Universal mode. The selected operating mode is indicated by the illuminated button.

Universal (preset)
The operating mode “Universal” is suitable for most applications in masonry. Metal objects, water-filled plastic pipes, electrical lines, and cables are indicated. Cavities in building brick or empty plastic pipes with a diameter of less than 2 cm may not be displayed. The maximum measuring depth is 6 cm.

Concrete
The operating mode “Concrete” is especially suitable for applications in reinforced concrete. Rebars, metal pipes, water-filled plastic pipes, electrical lines, and cables are indicated. The maximum measuring depth is 12cm.

Drywall
The operating mode “Drywall” is suitable for detecting joists, metal supports, electrical lines, and cables in drywalls (wood, plasterboard, etc.). Water- filled plastic pipes are also indicated. Empty plastic pipes are normally not detected. The maximum measuring depth is 6 cm.

Measuring Procedure

Locating objects
Position the measuring tool on/against the surface being inspected. If there is already an object below the measuring tool when it is placed down, the LED 2 lights up red if there is sufficient signal strength, the measuring indicator h deflects, and a signal sounds.
If an object has not yet been detected when the measuring tool is placed down, the procedure indicator j is displayed and the LED 2 lights up yellow. Move the measuring tool over the surface without lifting it off, until the procedure indicator j disappears. The LED 2 then lights up green at places where the measuring tool has not detected an object. When the measuring tool approaches an object, the deflection in the measuring indicator h increases and the LED 2 lights up red. The deflection decreases when the measuring tool moves away from an object. With small or deep-lying objects, the LED 2 can continue to light up yellow and the signal does not sound.

Determining the object’s center

If an object is detected, the LED 2 lights up red and, if there is sufficient signal strength, the orientation arrows k for determining the object’s center are displayed. To specifically locate the object’s center, move the measuring tool in the direction of the orientation arrows k. If the orientation arrows are not displayed, an object may nevertheless be located in the immediate vicinity.

The measuring indicator h indicates the maximum deflection when it is positioned over the center of an object, the LED 2 lights up red, and, if there is sufficient signal strength, the center cross i is displayed. To determine the object’s center more accurately, note the square which is shown in the immediate vicinity of the object’s center in addition to the center cross i if there is sufficient signal strength. Wider objects in the base material can be identified by a continuous, high amplitude of the measuring indicator h. The LED 2 lights up red.

• Always pay attention to all the signals of the measuring tool (LED, measuring indicator, orientation arrows). To rule out hazards, safeguard yourself before you drill, saw
  or rout in walls, by means of other information sources. Since the measuring results can be influenced by ambient conditions or the wall material, there may be a hazard even though the indicator does not indicate an object in the sensor range (there is no signal sound, and the LED 2 lights up green).

Power Cable
If a live wire is detected, display 3 also indicates a . The LED 2 flashes red and the signal sounds with a quick tone sequence.

Notes:
“Live” conductors are indicated in any operating mode. “Live” conductors can be detected easier when power consumers (e.g. lamps, machines) are connected to the sought conductor and switched on. Under certain conditions (such as below metal surfaces or behind surfaces with high water content), “live” conductors cannot be securely detected. The signal strength of a “live” conductor depends on the position of the cable. Therefore, apply further measurements in close proximity or use other information sources to check if a “live” conductor exists. Static electricity can lead to electric lines being indicated inaccurately, e.g. over a large area, or not at all. To improve the indication, place your free hand flat on the wall next to the measuring tool, in order to remove the static electricity.

• Hold the measuring tool at the intended grip area 10 only, so as not to influence the measurement.

Marking Objects
If required, detected objects can be marked. Perform measurement as described. Once you have found the boundaries or the center of an object, mark the location you were searching for at the top marking aid 1 and the side marking aid4. Connect both points with a vertical and horizontal line. The object is located at the intersection of the lines.

Working Advice

Temperature Control
Note: If the device is lifted off the wall, a signal may be shown temporarily.
When the temperature control indicator e lights up, the battery of the measuring tool is not within the operating temperature range or was subject to large variations in temperature. Change the battery or wait until it has once again reached the operating temperature range.

Warning Function
When display 3 indicates f and g, send the measuring tool to an authorized customer service agent. The measuring tool is no longer functional.
