Emergency Calls and GPS 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). CDM-9900's ALI Capability The Audiovox CDM-9900 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 CDM-9900's ALI capability is to be used for E911 purposes only. 144 Chapter 10

Emergency Calls and GPS
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 un-
der 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 Identifica-
tion = 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).
CDM-9900
’
s ALI Capability
The Audiovox CDM-9900 is an ALI-capable phone equipped with the GPS (Glo-
bal Positioning System: Satellite assisted location information system) receiver
supporting GPS based ALI-capable network to comply with the FCC
’
s ALI re-
quirements.
The network compliance with the above FCC requirements is dependent on:
(a) the use of digital technology by the wireless network; (b) GPS satellite sig-
nals being able to reach the handset (such transmissions do not always work
indoors, for example) ; and (c) handset signals reaching wireless
“
base sta-
tions
”
(atmospheric and environmental conditions may cause variations in hand-
set receiving signal strength).
Also the transmission of the ALI information is subject, in part, to system con-
straints within the wireless network to which the E911 signal is transmitted and
over which Audiovox has no control.
Finally, customers are advised that the CDM-9900
’
s ALI capability is to be used
for E911 purposes only.
