■ CASIO C771 TEMPORARY — ALI Capability
The CASIO C771 TEMPORARY is an ALI-capable phone equipped
with a GPS (Global Positioning System) receiver supporting a
satellite-based GPS ALI-capable network to comply with the FCC’s ALI
requirements.
The network compliance with the above FCC requirements is
dependent on: (a) the use of digital technology by the wireless network;
(b) GPS satellite signals being able to reach the handset (such
transmissions do not always work indoors, for example); and (c)
handset signals reaching wireless “base stations” (atmospheric and
environmental conditions may cause variations in handset receiving
signal strength).
Also the transmission of the ALI information is subject, in part, to
system constraints within the wireless network to which the E911 signal
is transmitted and over which PCD has no control. Finally, customers
are advised that the CASIO C771 TEMPORARY’s ALI capability is to
be used for E911 purposes only.
