Safety: Work with power off when accessing the control board or antenna connections.

Replace remote batteries: Install fresh, correct-type batteries in all FAAC remotes.
Inspect antenna: Ensure the antenna wire is fully extended and not cut. For external antennas, check the coax connector and mount location.
Relocate antenna: Move the antenna away from metal surfaces and closer to the door opening if possible.
Reduce interference: Keep Wi-Fi routers, LED drivers, and other RF-noisy devices away from the opener if possible.
Upgrade receiver/antenna: Install a higher-gain FAAC antenna or an external receiver with better sensitivity if range remains poor.

Do not coil the antenna tightly; this reduces its effectiveness.

Remote control range is very short; must be close to the FAAC opener for it to work.
