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 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 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 on, it periodically rechecks service availability or you can check 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 0.003 µw to 0.2 w 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). Maintaining Your Phone's Peak Performance There are several simple guidelines to operating your phone properly and maintaining safe, satisfactory service. ᮣ Hold the phone with the antenna up, fully-extended and over your shoulder. ᮣ Try not to ever hold, bend or twist the phone antenna. ᮣ Don't use the phone if the antenna is damaged. ᮣ Speak directly into the mouthpiece.
