. RF Test Mode Short-circuit the short-circuit point of the test mode, re-power on, check the temperature and humidity and emit continuously, and there will be LED indications at the same time 3. Transmit data 1) Transmission mode is ASK433.92MHZ 2.) After power-on, the default is CH1, and the push control mode is in the custom channel. After the channel is changed, the new channel data will be sent. Each channel is timed separately.
