Chapter 11 Touchscreen
11.1 Introduction
11.1.1 General information
The PPC-153's optional touchscreen incorporates advanced second-gen-
eration 5-wire resistive, impact-resistant capacitive, or surface acoustic
wave (SAW) technology. They allow 75%, 85%, and 91% light transmis-
sion respectively. The resistive and capacitive models have an antiglare
surface, but the SAW model does not. All models provide greatly
enhanced visual resolution. They also have new improved scratch-resis-
tant features.
The touchscreen is manufactured from UL-recognized components.
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, con-
trollers, and cables have been approved to FCC Class A and Class B stan-
dards.
