Understanding message menu items:
- Listening to the voice-mail or reading the pages/messages you've received.
First of all , the voice quality of your Samsung SPRINT Phone will always be at its best when the
antenna is fully raised. If you're inside a building , reception may be better near a window.
The quality of each call you make or receive depend on the signal strength in your area. You phone will
inform you of the current strength by displaying a number of the bars next to the signal strength icon.
The more bars displayed, the stronger the signal.
Understanding Power Save mode.
If you're trying to use your phone in an area where the signal is too weak, the Power Save feature will
automatically activate to conserve battery power when you've been unable to pick up a signal for 15
minutes. If you phone is on, it will periodically recheck service availability, or you can do so yourself
manually by pressing any key.
A message will be displayed on the screen any time Power Save has been activated
Understanding how your phone operates.
Your Samsung SPRINT Phone is basically a radio transmitter and receiver.
When it's turned on, it receives and transmits radio frequency(RF) signals. Your phone operates in the
frequency range 1.9 GHz and 800MHz. When your phone is in use, the system handling your call
control the power level.
Radio Frequency safety.
In 1991-1992, the Institute of Engineers(IEEE) and the American National Standards Institute(ANS joined
in updating ANSI's 1982 standard for safety levels with respect to human exposure to RF signals. More
than 120 scientists, engineers and physicians from universities, government health agencies and
industries developed this updated standard after reviewing the available body of research. In 1993, the
Federal Communications Commission(FCC) adopted this update standard in a regulation. In August 1996,
the FCC adopt a hybrid standard consisting of the existing ANSI/IEEE standard and the guidelines
published by the National Council of Radiation Protection and Measurements(NCRP).
The design of the Samsung SPRINT Phone complies with these updated standard. Of course, if you
want to limit RF exposure even further than the updated standard, you can choose to control the
duration of your calls and operate your phone in the most power-ficient manner.
Maintaining your phone's peak performance.
