Diaľkový ovládač Sony RMF-TX221 pre TV s podsvietenými tlačidlami

Sony RMF-TX221 is a replacement TV remote control designed for convenient operation of compatible Sony televisions. It provides a familiar button layout for channel selection, volume adjustment and menu navigation, and includes backlit buttons to support use in low-light environments. The remote is intended as a direct substitute for an original controller or as an additional handset for everyday home use, offering straightforward setup and reliable basic functionality.

Advantages

The backlit button design improves visibility in dark rooms without requiring additional lighting. A standard ergonomic layout groups frequently used controls—power, channel, volume and navigation—within easy reach, reducing the time needed to learn the remote. The model is built for basic durability and consistent infrared communication with compatible TV models, ensuring predictable response for common functions such as changing channels, adjusting volume and accessing on-screen menus.

How to use

Insert the required batteries according to the polarity markings in the battery compartment, then point the remote toward the television's IR receiver.

Confirm model compatibility with your Sony television before purchase to ensure full function coverage.
