Bosch Truvo Original Instructions Manual page 25

– Switch the measuring tool on and off again within 3 s using the on/off
switch (2). The light-up ring (5) will flash red slowly for the 3 s to indicate
readiness for calibration.
– Switch the measuring tool back on within 0.5 s. The calibration will start
and take roughly 6 s. During calibration, the light-up ring (5) flashes
green quickly. Once the light-up ring (5) lights up green continuously, the
calibration is complete and the measuring tool is ready to use.
Note: If the sequence of switching off and switching on again is not ob-
served, calibration will not take place. The light-up ring (5) continues to light
up yellow or red even though there is no metal nearby. In this case, repeat
the calibration in the exact same way.
