Aiphone has always recognized that there are features and functions that our products don't have. In response we've created a manual detailing the in-field customization of our units to do some of the more frequently requested functions. Called the "Modification Manual" and now in it's fifteenth year, it has been an invaluable source of knowledge for in field technicians. It is available free of charge for the first time here.
