Radio Frequency (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 radio frequency (RF) signals. When you use your
phone, the system handling your call controls the power level. This power
can range from 0.006 watt to 0.2 watt in digital mode.
Knowing Radio Frequency 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 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 0.866 inches (2.2 centimeters) from your body when
transmitting. Use of non-approved accessories may violate FCC RF exposure
guidelines.

Specific Absorption Rates (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-2700 by SANYO
¨
are:
Cellular CDMA mode (Part 22):
Head: 1.25 W/kg; Body-worn: 0.647 W/kg
PCS mode (Part 24):
Head: 1.16 W/kg; Body-worn: 0.524 W/kg
