The D’San Audience Signal Light (4” High Solid LED Digits) allows you to simplify the process of presentations by signaling the speaker when to start or stop. With 4” (10.16cm) high 7-segment LED digits and red, yellow, and green colored warning lights, the signal light provides a clear cue to the speaker. You can use the signal light to display the time remaining for the presenter’s reference. When not connected to the Limitimer console, the signal light displays the time of the day along with battery backup. You can directly power the signal light from the Limitimer unit or connect it to an AC outlet up to 200’ (60.9m) away. – See more at: http://www.socalps.com/av/accessories/dsan-asl-4-nd3/#sthash.FjpHs9XR.dpuf
