Error Message
If a measurement cannot be performed correctly, the error message will appear in the dis-
play.
Try to perform the measuring process again.
If the error message appears again, switch the measuring tool off and back on, and
start the measurement again.
The measuring tool monitors correct operation in every measurement. If a defect is detec-
ted, all indicators on the display will flash. In this case, or if you are unable to rectify an er-
ror using the corrective measures, send the measuring tool to the Bosch after-sales ser-
vice via your dealer.
Maintenance and Service
Maintenance and Cleaning
Keep the measuring tool clean at all times.
Never immerse the measuring tool in water or other liquids.
Wipe off any dirt using a damp, soft cloth. Do not use any detergents or solvents.
Take particular care of the reception lens (11), which must be handled with the same level
of care you would give to a pair of glasses or a camera lens.
