accurately as possible. Never terminate an emergency call until you
have received clearance to do so.
FCC Enhanced 911 (E911) Rules
Background
The Federal Communications Commission (FCC) requires wireless
carriers to transmit specific latitude and longitude location (Automatic
Location Identification = ALI) information as well as “911” calls to
Public Safety Answering Points (PSAPs) to identify the location of
the caller in case of emergency. Generally, the rules require that
carriers identify an E911 caller’s location within 50 meters of the actual
location for 67 percent of calls and within 150 meters of the actual
location for 95 percent of calls.
CASIO G’zOne Ravine™ — ALI Capability
The Ravine™ 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 Ravine’s ALI capability is to be
used for E911 purposes only.
