Marking Objects
If required, detected objects can be marked. At the maximum amplitude
of measuring indicator c, the centre of the object is directly under the sig-
nal LED 2 in the centre of the sensor area 7. The boundaries of an object
can be found where the signal LED 2 changes from orange to red. Mark the
desired location to the surface with help of the three marking aides 1.
"AutoCal" Calibration Indicator
When the check mark behind the "AutoCal" calibration indicator d flash-
es for longer periods or if it is not displayed anymore, reliable scanning is
no longer possible. In this case, send in the measuring tool to an author-
ised Bosch after-sales service agent.
Maintenance and Service
Maintenance and Cleaning
When measuring indicator c indicates a continuously high amplitude,
even though there is no metal object near the measuring tool, the measur-
ing tool can be manually calibrated. For this, remove all objects near the
measuring tool (including your wrist watch or rings made of metal) and
hold the measuring tool up. With the measuring tool switched off, press
and hold the On/Off button 4 until signal LED 2 lights up orange. Then re-
lease the button. When the calibration was successful, the measuring tool
will automatically restart after a few seconds, and will be ready for opera-
tion again.
When the signal LED 2 alternately lights up green and orange during the
calibration, a metal object is too close to the measuring tool and calibra-
tion is not possible. Remove the metal object and repeat the calibration
process.
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 7 on
the front or back side of the measuring tool.
If the measuring tool should fail despite the care taken in manufacturing
and testing procedures, repair should be carried out by an authorised af-
ter-sales service centre for Bosch power tools. Do not open the measuring
tool yourself.
In all correspondence and spare parts orders, please always include the
10-digit article number given on the type plate of the measuring tool.
