EMERGENCY CALLS
EMERGENCY CALLS
Never rely solely upon your wireless phone for essen-
tial 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 accu-
rately 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) re-
quires 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).
9155-GPX’s ALI Capability
The Audiovox 9155-GPX 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 require-
ments is dependent on: (a) the use of digital technol-
ogy 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) hand-
set signals reaching wireless “base stations” (atmo-
spheric and environmental conditions may cause varia-
tions in handset receiving signal strength).
Also the transmission of the ALI information is subject,
in part, to system constraints within the wireless net-
work to which the E911 signal is transmitted and over
which Audiovox has no control.
Finally, customers are advised that the 9155-GPX’s ALI
capability is to be used for E911 purposes only.
