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 or you can check it yourself by pressing any key. Anytime the
Power Save feature is activated, a message displays 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 radio frequency (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 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).
Maintaining Your Phone’s Peak Performance
There are several simple guidelines for operating your phone properly and
maintaining safe, satisfactory service.
• Speak directly into the mouthpiece.
