The DXT-61/EC is a battery powered, portable, miniature pendant transmitter designed for use with Linear's DX Format receivers. The transmitter can be used in a limitless number of wireless remote control applications. Pressing the button on the transmitter sends a digitally coded wireless signal to its companion receiver.

The digital DX code format features over a million possible codes. Each DX transmitter is precoded at the factory to a unique code, so no field coding is required. The transmitter can send a signal for up to 10 seconds with each button activation.

For versatility, the transmitter code can be programmed into any receiver channel. Receivers must be programmed to the transmitter code before system testing and operation. DX Format digital receivers are programmed by "Learning" the preset factory code from the transmitter.
