Caution:
- DTMF audio controller must use stable work of DC 12V power supply (recommendations 2A or above the power adapter)
- Remote control the controller by a mobile phone, the receiver must be the phone with a 3.5MM audio interface, and the transmitter can be a cell phone or landline
- The receiver of the phone must output a sound (not muted), or they will not control relays.
