Emergency Calls
Never rely solely upon your wireless phone for essential
communications (e.g. medical emergencies), if it can be avoided,
since a wireless phone requires a complex combination of radio
signals, relay stations, and landline networks for its operation.
Consequently, emergency calls may not always be possible under all
conditions on all wireless phone systems.
Your wireless phone, however, may sometimes be the only available
means of communication at the scene of an accident. When making
an emergency call, always give the recipient all necessary
information as 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. Accuracy requirement for
ALI information by FCC E911 rules is within 50 meters for 67 percent
of calls and within 150 meters for 95 percent of calls (FCC's ALI
Requirements).
Your Phone's ALI Capability
This phone is an ALI-capable phone equipped with the GPS (Global
Positioning System: Satellite assisted location information system)
receiver supporting GPS based 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 Audiovox has no control.
Finally, customers are advised that the phone's ALI capability is to be
used for E911 purposes only.
