protections in the measuring tool may
be compromised if the measuring tool is not
used in accordance with the instructions
provided.

SAVE THESE INSTRUCTIONS FOR FUTURE REFERENCE.

▶ Have the measuring tool repaired only through qualified
specialists using original spare parts. This ensures
that the safety of the measuring tool is maintained.
▶ Do not operate the measuring tool in explosive environments,
such as in the presence of flammable liquids,
gases or dusts. 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. Use of any other battery packs may create a
risk of injury and fire.
▶ When 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 eyes, additionally
seek medical help. Liquid ejected from the battery
may cause irritation or burns.
▶ Do not open the battery pack. Danger of short-circuiting.
Protect the battery pack against heat, e.g.,
against continuous intense sunlight, fire,
water, and moisture. Danger of explosion.
▶ In case of damage and improper use of the battery
pack, vapours may be emitted. Provide for fresh air and
seek medical help in case of complaints. The vapours
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.

Assembly

The measuring tool can be operated either with a battery pack  13 or with AA batteries.

▶ Remove the batteries/rechargeable batteries from the  measuring tool when not using it for longer periods.  When storing for longer periods, the batteries/rechargeable batteries can corrode and self-discharge.

Battery Charging (see figure C)

▶ Use only the battery chargers listed on the accessories  page. Only these battery chargers are matched to the lithiumion battery pack that can be used in your measuring tool.

Note: The battery supplied is partially charged. To ensure full  capacity of the battery, completely charge the battery in the  battery charger before using your power tool for the first time. The lithium-ion battery can be charged at any time without re

ducing its service life. Interrupting the charging procedure  does not damage the battery.

The “Electronic Cell Protection (ECP)” protects the lithium ion battery pack against deep discharging. When the battery  pack is discharged, the measuring tool is switched off by a  protective circuit.

▶ Following the automatic shut off of the measuring tool,  do not continue to press the On/Off button. The battery  can be damaged.

To remove the battery 13 press the unlocking buttons 12 and  pull the battery back and out of the measuring tool. Do not ex ert any force.

Battery has 10% capacity or less

Change battery

Operation

▶ Protect the measuring tool against moisture and direct  sun light.

▶ Do not subject the measuring tool to extreme tempera tures 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 ad just to the ambient temperature before putting it into oper ation.

▶ Hold the measuring tool at the intended grip area 10  only, so as not to influence the measurement.
▶ Use or operation of transmitting systems, such as  WLAN, UMTS, radar, transmitter masts or microwaves,  in the 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 in formation 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, 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, the dis play 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  differ 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, wa ter-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 dis played. The maximum measuring depth is 6 cm.

Concrete

The operating mode “Concrete” is especially suit able for applications in reinforced concrete. Re bars, 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 de tecting 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 in spected.

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 dis played 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 plac es where the measuring tool has not detected an object. When the measuring tool approaches an object, the deflec tion 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 centre

If an object is detected, the LED 2 lights up red and, if there is  sufficient signal strength, the orientation arrows k for deter mining the object’s centre are displayed. To specifically lo cate the object’s centre, 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 centre of an object, the LED 2 lights up red and, if there is sufficient signal strength, the cen tre cross i is displayed. To determine the object’s centre more  accurately, note the square which is shown in the immediate  vicinity of the object’s centre in addition to the centre 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, the 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. There

fore, 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 in accurately, 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 meas urement as described. Once you have found the boundaries  or the centre of an object, mark the location you were search

ing for at the top marking aid 1 and the side marking aid 4.  Connect both points with a vertical and horizontal line. The  object is located at the intersection of the lines.

Troubleshooting – Causes and Corrective Measures

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

Error Cause Corrective Measure Measuring tool cannot be switched on. Battery pack empty Battery Charging Batteries empty Replace batteries

Measuring tool switched on but does not react Remove and reinsert rechargeable batteries/batteries “Service required” Measuring tool has a fault Send measuring tool to customer ser vice agent “Battery temperature has fallen short of/exceeded battery temperature range” Wait until the permitted temperature  range of the battery has been reached  or change the battery “Stong radio signal detected” If possible, remove the interfering radio waves, e.g. WLAN, UMTS, radar, transmitter masts or microwaves.

Maintenance and Service

Maintenance and Cleaning

▶ Check the measuring tool each time before use. In case  of visible damage or loose components inside the measuring tool, safe function can no longer be ensured.

Keep the measuring tool clean and dry at all times to ensure  proper and safe working.

Do not immerse the measuring tool in water or other fluids. Wipe away debris or contamination with a dry, soft cloth. Do  not use cleaning agents or solvents.

In order not to affect the measuring function, decals/stickers or  name plates, especially metal ones, may not be attached in the  sensor area 14 on the front or back side of the measuring tool.
