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.

The C781R3 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 Hitachi HTA has no control. Finally, customers are advised that the 

C781R3’s ALI capability is to be used for E911 purposes only.

The “911” call service is available even in the lock mode.
