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 wireless 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).
