Understanding how your phone operates.
Your Sprint PCS 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 of 1.9 GHz. When your phone is in use, the system
handling your call controls the power level.
Radio frequency safety.
In 1991–1992, the Institute of Electrical and Electronics
Engineers (IEEE) and the American National Standards Institute
(ANSI) 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
updated standard in a regulation. In August 1996, the FCC
adopted 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 Sprint PCS Phone complies with these updated
standards. 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-efficient manner.

Maintaining your phone's peak performance.
To operate your phone properly – that is, to maintain safe and
satisfactory service – you should follow these rules:
For best reception, extend the antenna fully.
Hold the phone with the antenna up and over your shoulder.
Do not hold the phone antenna at any time.
Do not use the phone with a damaged antenna.
Speak directly into the mouthpiece.
Avoid exposing your phone and accessories to rain or liquid
spills. If your phone does get wet, turn the power off immediately
and remove the battery pack. If it is inoperable, you should
return it to a Sprint PCS Center or call Sprint PCS Customer Care
for service.
Only authorized personnel should service your phone and its
accessories. Faulty service may invalidate the warranty.
