10.1 Introduction
10.1.1 General information
The PPC-120/140's optional touchscreen incorporates advanced second-generation 5-wire resistive technology. It allows 75% light transmission and has an antiglare surface. This produces greatly enhanced visual resolution. It also has a newly improved scratch-resistant hard coating.
The touchscreen is manufactured from UL-recognized components (file no. E133802). When properly installed, the touchscreen's ball impact resistance meets the UL 1950 standard. Its fire resistance meets the UL-746C, 19 mm (0.75") flame test standard. Systems incorporating the touchscreen, controllers, and cables have been approved to FCC class A and B standards.
