Understanding how your phone oper- ates.

Your phone is basically a radio transmitter and receiv- er.When it’s turned on, it receives and transmits radio frequency (RF) signals.When your phone is in use, the system handling your call controls the power level.This power level can range from 0.006 watts to 0.2 watts.

Radio frequency safety.

In 1991—1992, 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 scien- tists, engineers, and physicians from universities, gov- ernment health agencies, and industry developed this updated standard after reviewing the available body of research. In 1993, the Federal Communications (FCC) adopted this updated standard in a regulation. In August 1996, the FCC adopted a hybrid standard consisting of the existing ANSI/IEEE standard and the guidelines published by the National Council of Radiation Protection and Measurements (NCRP).

The design of the phone complies with these updat- ed standards. Of course, if you want to limit RF expo- sure even further than the updated standard, you can choose to control the duration of your calls and oper- ate your phone in the most power-efficient manner.

Maintaining your phone’s peak perfor- mance.

To operate your phone properly — that is, to main- tain safe and satisfactory service — you should fol- low these rules:

¤For best reception, extend the antenna fully.

¤Hold the phone with the antenna up and over your shoulder.

¤Do not hold, bend, or twist the phone antenna at any time.

¤Close the phone antenna when not on a call.

¤Do not use the phone with a damaged antenna.

¤Speak directly into the microphone.

¤Avoid exposing your phone and accessories to rain or liquid spills. If your phone gets wet, turn the power off immediately, remove the battery, and allow the phone an battery to air dry for 10 hours (in normal room temperature and humidi- ty). If after the 10 hour drying time, the phone is inoperable, you should return it to the store where you purchased it, or a Samsung authorized service center.

Only Samsung authorized personnel should service your phone and its accessories. Faulty service may invalidate the warranty.
