Used AT&T 728A Intercom System/Baby Monitor

This AT & T 728A Intercom System is used but in very good working condition. Each unit measures 6.5" x 5" x 1.5". Each are lightweight. I plugged both in and tested all 3 channels, all 3 buttons and both volume control dials. This intercom system can be used at home, in the office or as a baby monitor. Each has a page button, a talk button and an auto button that can make it so you don't have to hold down the talk button to communicate with the other unit. Each unit is equipped with a 6 foot power cord. Each can be placed on a table, nightstand or can be mounted on a wall. Each comes with a display light that is green when not in use and orange when talking or paging. Comes in it's original box with an 19 page instruction manual.
