Maintenance and Cleaning
When the measuring indicator c continuously shows an
amplitude even though there is no metal object in the
vicinity of the measuring tool, the measuring tool can
be calibrated manually. For this, remove all objects in
the vicinity of the measuring tool (including wrist
watches or rings of metal) and hold the measuring tool
up in the air. With the measuring tool switched off,
press the On/Off button 4 until the illuminated ring 1
lights up red and green at the same time. Then release
the button. When the calibration process was success-
ful, the measuring tool will start over after a few sec-
onds and is then ready for operation.
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, de-
cals/stickers or name plates, especially metal ones,
may not be attached in the sensor area 5 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 after-sales service cen-
tre 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.
