SEE and hear baby’s call with the Sound ’n Lights Monitor! This monitor has sound lights that let you not only hear, but actually “see” the different levels of your baby’s activity. There are two channels to minimize interference. For added convenience, the Sound ’n Lights Monitor has a night light built into the transmitter for baby’s room, and a low battery indicator. Durable, flexible antennas on the Sound ’n Lights baby monitor allow for greater range and excellent clarity. And the receiver is AC-powered, or battery-powered for portability.
