The E Series defibrillator features a suitcase-style design with a protective roll cage, allowing EMS customers to carry or store the device more easily. E-series also provides an EasyRead Tri-Mode Display for use in pitch dark or direct sunlight, providing readability and complete views of critical patient information from virtually any angle and is equipped with a built-in GPS clock, allowing customers to automatically synchronize all of their dispatch, defibrillator, and intervention call times, improving overall data accuracy.
