16 Important Safety Information
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 a
Cricket-supplied or Cricket-approved carrying case,
holster or other body-worn accessory. If you do not
use a body-worn accessory, ensure the antennas are
at least 0.591 inches (1.5 centimeters) from your
body when transmitting. Use of non-Cricket-approved
accessories may violate FCC RF exposure guidelines.
Other accessories used with this phone for body-
worn operations must not contain any metallic
components and must provide at least
0.591 inches (1.5 centimeters) separation distance
between the antennas and the user’s body.

Specific Absorption Rates (SAR) for
Wireless Phones
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
