some areas, the disposal of batteries in household or business
trash may be prohibited.
Radio Frequency (RF) Energy
Understanding How Your Device Operates
Your device is basically a radio transmitter and receiver. When
it’s turned on, it receives and transmits radio frequency (RF)
signals. When you use your device, 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 device 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 a Sprint-supplied or
Sprint-approved carrying case, holster or other body-worn
accessory. If you do not use a body-worn accessory, ensure
the antenna is at least
7/16 inch
(
1.5 centimeters
) from your
body when transmitting. Use of non-Sprint-approved
accessories may violate FCC RF exposure guidelines.
For more information about RF exposure, visit the FCC website
at
Specific Absorption Rates (SAR) for Wireless
Devices
The SAR value corresponds to the relative amount of RF
energy absorbed into 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.
