Error Message

If a measurement cannot be performed correctly, the error message Error will appear in
the display.
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 de-
fect is detected, the display will indicate only the symbol shown opposite and
the measuring tool switches itself off. In this case, have the measuring tool
checked by an after-sales service agent for Bosch power tools.
