Aiphone JBW-BA Long-Distance Adapter for JA, JF, and KC Series intercom systems

hello my name is graham burns with eps and today i'm going to go over some of the basics of the aphone jf series intercom what we have here is the desk master station which is where the calls come into and out next to the door you will have the door station where you initiate the call from so if somebody were to call in on the unit the camera will come up you'll hear the microphone come on you want to hold the talk button down until the red light comes on hello can i help you i am here for my appointment all right go ahead and come in now to hear the other person on the other line i have to let go of the talk button so once you've let them know to come in you can hit the menu button there will be this little key symbol right here you hold that down the symbol will show up here showing that the door should be unlocking good standard practice is to hold this down until the door opens that
