[. . . ] When the battery indication a in the display lights up, measuring is possible for approx. 1 h when using alkali-manganese batteries (service life is shorter with rechargeable batteries). When the battery indication a and the illuminated ring 1 (red) are flashing, measuring is no longer possible and the battery or the rechargeable battery respectively, must be replaced. [. . . ] Other wires/conductors (carrying DC, higher/lower frequency or voltage) as well as "dead" wires/conductors cannot be found reliably, but are possibly indicated as metal objects. The scan for "live" wires/conductors takes place automatically for each measurement. when a "live" wire/connductor is detected , the indicator b appears in the display. Move the measuring tool over the surface repeatedly in order to localise the "live" wire. After moving the measuring tool over the surface several times, the position of the "live" wire/conductor can be indicated quite precisely. If the measuring tool is very close to the wire/conductor, then the illuminated ring 1 lights up red and the signal tone sounds with rapid tone sequence. "Live" wires/conductors can be detected easier when power consumers (e. , lamps, appliances) are connected to the wire/conductor being sought and switched on. Wires/conductors with 110 V, 230 V and 400 V (three-phase current) are detected with about the same scan capacity. Under certain conditions (such as when behind metal surfaces or behind surfaces with high water content), "live" wires/conductors cannot be detected with certainty. When measuring indicator c is indicated over a larger range, then the material is screening-off electrically and the scan for "live" wires/conductors is not reliable. On condition of the principle, the measuring values can be impaired through certain ambient conditions. , the proximity of other equipment that produce strong magnetic or electromagnetic fields, moisture, metallic building materials, foil-laminated insulation materials or conductive wallpaper. Construction plans) before drilling, sawing or routing into walls, ceilings or floors. Where the amplitude of measuring indication c is at its maximum, the centre of the object is located below marking hole 2. The limits of an object are indicated by the colour change of the illuminated ring 1 from green to red. Using a pen, mark the sought after location through the marking hole 2. "AutoCal" Calibration Indicator When the check mark behind the "AutoCal" calibration indicator d flashes for longer periods or if it is not displayed anymore, reliable scanning is no longer possible. [. . . ] Battery packs/batteries: Do not dispose of battery packs/batteries into household waste, fire or water. battery packs/batteries should be collected , recycled or disposed of in an environmental-friendly manner. Only for EC countries: Defective or dead out battery packs/batteries must be recycled according the guideline 91/157/EEC. [. . . ]
