CAMERA
Do not aim your camera at the sun. The sunlight passing
through the camera lens may cause damage to the camera.
Do not use your camera’s flash close to a person’s eyes. This
may cause the person to lose eyesight temporarily and result in
an accident.
EMERGENCY CALLS
Never rely solely upon your wireless phone for essential com-
munications (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 wire-
less 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 neces-
sary 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 loca-
tion (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.
CDM8932’s ALI Capability
The CDM8932 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 hand-
set (such transmissions do not always work indoors, for exam-
ple) ; and (c) handset signals reaching wireless “base stations”
(atmospheric and environmental conditions may cause varia-
tions in handset receiving signal strength).
