256 Section 4A: Safety
Getting the Most Out of Your Reception
Keeping Tabs on Signal Strength
The quality of each call you make or receive depends on the signal strength
in your area. Your phone informs you of the current signal strength by
displaying a number of bars next to the signal strength icon. The more bars
displayed, the stronger the signal. If you’re inside a building, being near a
window may give you better reception.
Understanding the Power Save Feature
If your phone is unable to find a signal after 15 minutes of searching, a
Power Save feature is automatically activated. If your phone is active, it
periodically rechecks service availability; you can also check it yourself by
pressing any key. Anytime the Power Save feature is activated, a message is
displayed on the screen. When a signal is found, your phone returns to
standby mode.
Understanding How Your Phone Operates
Your phone is basically a radio transmitter and receiver. When it’s turned
on, it receives and transmits radiofrequency (RF) signals. When you use
your phone, the system handling your call controls the power level. This
power can range from 0.006 watts to 0.2 watts in digital mode.
Knowing Radio Frequency Safety
The design of your Sprint PCS Phone complies with updated NCRP
standards described below.
In 1991-92, 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 hybrid standard
consisting of the existing ANSI/IEEE standard and the guidelines published
by the National Council of Radiation Protection and Measurements (NCRP).
