Malfunctions with Error Codes

The error code of a malfunction is shown on the display.
– R ectify the malfunction (see "Corrective Measure").
– Afterwards, simultaneously press the centre line mode button 19 and audio signal/volume button 24.
If the malfunction was successfully rectified, the error code indication goes out and automatic levelling will
start (see "Automatic Levelling during Operation", page40).
If the malfunction persists, have the measuring tool checked by a Bosch customer service agent.
