The new 1501L offers a higher resolution LCD screen for detailed, life-like images, and the LED backlight uses less power. It's easy to adjust the height of the video screen for use on a high counter or on a low desktop. Any Series 1500 audio counter station can easily be upgraded to an audio/video counter station with a Model 1502L video interface. The 1502L connects to 1500A, 1500 (with bracket) and 1533 via one Cat5 cable.
