Dual-Mode
The NeoPoint 1600 is a cellular band, dual-mode wireless phone, compatible with
both digital (CDMA) and analog (AMPS) networks operating at 800MHz.
The term dual-mode represents the ability of your NeoPoint 1600 to transmit and
receive signals from both analog and digital cellular phone systems.
The benefits of having a dual-mode phone include being able to use your phone when
traveling in an area where CDMA digital service is not yet activated. Your NeoPoint
1600 phone will automatically find analog service, allowing your call to be
processed.
About CDMA...
Code division multiple access (CDMA) is the type of digital wireless transmission
that the NeoPoint phone employs. The following sections provide information on
CDMA performance and advantages. These sections are designed to help you
understand how to better use your NeoPoint phone.
Signal Strength and Phone Performance
Like other portable wireless phones, signal strength is affected by the surrounding
environment of the user. Buildings, parking garages, elevators, and basements are
some examples of structures that reduce signal strength. Problems initializing a call,
muting of the audio during a call, or a call drop are signs of low signal strength.
Moving toward a window (if indoors) or open space (if outside) and extending the
antenna fully are ways to optimize signal strength. Traveling in a vehicle through
varying terrain, tunnels, or near tall buildings may also cause rapid changes in signal
strength.
