E9 displayed, operator will not accept new remote controls or loses all programmed transmitters.

Safety first: Keep clear of the door while testing remote operation.

• Confirm programming steps: Follow the Garador manual exactly for adding a new hand transmitter (e.g., press and hold 'P' until LED flashes, then press remote button).
• Clear memory: Perform a full erase of all remotes from the receiver memory (often holding the learn button for 10–20 seconds). Then re‑add remotes one by one.
• Reduce interference: Move Wi‑Fi routers, LED lighting drivers, or other RF devices away from the operator if possible. Test with the vehicle parked outside the garage to rule out shielding.
• Check antenna: Ensure the Garador receiver antenna wire is intact, not cut short, and routed away from metal surfaces.
• Replace receiver module: If the operator still shows E9 or will not store remotes, replace the plug‑in Garador radio receiver module or the main board if the receiver is integrated.
