If you currently own the 418 Mhz model, you'll want to purchase additional 418 MHz RF transmitters for each additional component's remote control. You'll want to choose your radio frequency transmitter based off of your existing Remote Extender Plus receiver.
Use this RF transmitter to add radio frequency signals (418 or 433 MHz) to a component's remote control for use with the Remote Extender Plus! When adding additional components to your existing Remote Extender Plus system, you'll need to insert a separate RF Transmitter into each new remote control being used (systems using a universal remote will only need 1 RF Transmitter).
