Radiofrequency (RF) Energy
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 Radiofrequency 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).
Body-Worn Operation
To maintain compliance with FCC RF exposure guidelines, if you wear a handset on your body, use
the PCS supplied or approved carrying case, holster or other body-worn accessory. If you do not use a
body-worn accessory, ensure the antenna is at least [
2.2
] centimeters from your body when
transmitting. Use of non-PSC approved accessories may violate FCC RF exposure guidelines.

Specific Absorption Rate (SAR) for Wireless Phones
The SAR is a value that corresponds to the relative amount of RF energy absorbed in the head of a
user of a wireless handset. The SAR value of a phone is the result of an extensive testing, measuring
and calculation process. It does not represent how much RF the phone emits. All phone models are
tested at their highest value in strict laboratory settings. But when in operation, the SAR of a phone
can be substantially less than the level reported to the FCC. This is because of a variety of factors
including its proximity to a base station antenna, phone design and other factors. What is important
to remember is that each phone meets strict federal guidelines. Variations in SARs do not represent
a variation in safety.
All phones must meet the federal standard, which incorporates a substantial margin of safety. As
stated above, variations in SAR values between different model phones do not mean variations in
safety. SAR values at or below the federal standard of 1.6 W/kg are considered safe for use by the
public.
The highest reported SAR values of the SCP-3200 are:
Cellular CDMA modes (Part 22) - Head: [
1.25
] W/kg; Body-worn: [
0.362
] W/kg
PCS CDMA mode (Part 24) - Head: [
1.41
] W/kg; Body-worn: [
0.295
W/kg
