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 suc-
cessful, the measuring tool will start over after a few seconds 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, decals/stickers or
name plates, especially metal ones, may not be attached in the sen-
sor area 5 on the front or back side of the measuring tool.
If the measuring tool should fail despite the care taken in manufac-
turing and testing procedures, repair should be carried out by an
authorized after-sales service centre for Bosch power tools.
In all correspondence and spare parts orders, please always include
the 10-digit article number given on the type plate of the measuring
tool.
