Very frustrated because no instructions included with system on how to work it. Have contacted company asking for instructions and NO response. I guess because they already have my money. I have tried to search on line for instructions NO LUCK!! This may be a great system but unfortunately I can't use it. DO NOT BUY UNLESS YOU ARE FAMILIAR HOW INTERCOM SYSTEMS WORK.
