When it may not be suitable
This infrared remote requires line-of-sight to the TV’s IR receiver and will not function through walls or with devices that rely on Bluetooth or RF protocols. It does not provide advanced smart-TV features that depend on network connectivity, voice control, or motion pointers. If your TV model uses proprietary wireless pairing or extended multimedia controls, this replacement may not support those functions.
