Safety 99SafetySafetyGetting the Most Out of Your ReceptionKeeping Tabs on Signal StrengthThe quality of each call you make or receive depends on the signal strength inyour area. Your phone informs you of the current signal strength by displaying anumber of bars next to the signal strength icon. The more bars displayed, thestronger the signal. If you’re inside a building, being near a window may give youbetter reception.Understanding the Power Save FeatureIf your phone is unable to find a signal after 15 minutes of searching, a PowerSave feature is automatically activated. If your phone is active, it periodicallyrechecks 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 OperatesYour phone is basically a radio transmitter and receiver. When it’s turned on, itreceives and transmits radio frequency (RF) signals. When you use your phone, thesystem handling your call controls the power level. This power can range from0.006 watts to 0.2 watts in digital mode.Knowing Radio Frequency SafetyThe design of your phone complies with updated NCRP standards described below.In 1991-92, the Institute of Electrical and Electronics Engineers (IEEE) and theAmerican National Standards Institute (ANSI) joined in updating ANSI’s 1982standard for safety levels with respect to human exposure to RF signals. More than120 scientists, engineers and physicians from universities, government healthagencies, and industries developed this updated standard after reviewing theavailable body of research. In 1993, the Federal Communications Commission(FCC) adopted this updated standard in a regulation. In August 1996, the FCCadopted a hybrid standard consisting of the existing ANSI/IEEE standard and theguidelines published by the National Council of Radiation Protection andMeasurements (NCRP).
