CAME garage door opener remote range is very short; you must be very close to the door for it to work

Safety first: Test remotes from a safe distance where you can still see the door.

Steps:

• Replace batteries: Fit new batteries in all remotes.
• Check antenna: Ensure the antenna wire is fully extended and not coiled inside the housing. For external antennas, mount vertically and clear of metal surfaces.
• Reduce interference: Move LED lamps, Wi‑Fi routers, or other RF devices away from the opener if possible.
• Test with another receiver: If range remains poor, the receiver module may be failing and should be replaced.

Consider upgrading to a higher‑gain external CAME antenna for improved range.
