Chapter 5 Touchscreen Interface

5.1 Introduction

5.1.1 General Information

The POC-195's optional touchscreen incorporates advanced second-gen-
eration 5-wire resistive technology for 75% light transmission. The resis-
tive and capacitive models have an antiglare surface. All models provide
greatly enhanced visual resolution. They also have improved scratch-
resistant features. The touchscreen is manufactured from UL-recognized
components. When properly installed, the touchscreen's ball impact resis-
tance meets the UL 1950 standard. Its fire resistance meets the UL-746C,
19 mm (0.75") flame test standard. Systems incorporating the touch-
screen, controllers, and cables have been approved to FCC Class A and
Class B standards.
