Recalibrating the Measuring Tool
If a metal object is indicated and the measuring indicator (b) indicates a continuously
high amplitude, even though there is no metal object near the measuring tool, the meas-
uring tool can be manually recalibrated.
–
Ensure that the battery charge indicator (d) 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.
– To switch to calibration mode, simultaneously press the on/off button (7) and the au-
dio signal button (6). Press and hold both buttons (for approx. 5–10 s) until the light-
up ring (1) flashes red.
– To start recalibration, press and hold the audio signal button (6) (for approx. 5−10 s)
until the light-up ring (1) lights up red.
– 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 does not start, send it to an authorised Bosch after-sales service centre.
