When the transmitter button is pressed, the corresponding channel outputs a high level. When the button is released, it returns to a low level, with a VT (valid transmission) pulse output.
Example: If button A has been learned by channel D0, pressing button A will make channel D0 output a high level; releasing the button will return it to a low level. Other channels are not affected.

Note about distance:

If the distance required for far, can be connected to the 1/4 wavelength of the antenna, generally use 50 ohm single conductor, the length of the antenna 315M of about 23cm, 433M of about 17cm;

The position of the antenna has also affected the reception of the module, install the antenna as straight as possible away from the shield, high pressure, and interference sources;
