Robot mower shows E19 and stops; often after hitting a solid obstacle or curb.

Safety first: Turn OFF the mower and inspect it in a safe, well‑lit area.

• Visual inspection: Check the outer shell and chassis for cracks, deformation, or signs of heavy impact.
• Check internal mounts: If user‑serviceable, open the housing and ensure the main board and sensor modules are firmly screwed down and not loose.
• Reset orientation: Place the mower on a perfectly level surface, power ON, and allow it to complete its startup. Some Cedrus models recalibrate the gyro at startup.
• Boundary adjustment: Move the boundary wire further from hard obstacles to reduce future impacts.
• Service if needed: If E19 persists or the mower drives erratically, the gyro sensor or chassis may be damaged and should be evaluated by a Cedrus technician.
