Exposure to Radio Frequency Signals
Your Iridium Extreme® PTT device is a low power radio transmitter and
receiver. When it is ON, it receives and also sends out radio frequency
(RF) signals. Your Iridium Extreme® PTT device is designed to comply with
local regulatory requirements in your country concerning the exposure of
human beings to RF frequency.
International agencies have set standards and recommendations for the
protection of public exposure to RF electromagnetic energy.
The design of your phone complies with these standards when used as
described under “Phone Mode Operation” on page 51.
This product is compliant with Industry Canada RSS-102 for RF Exposure.

1. Safety
4Iridium Extreme® PTT User Manual
Specic Absorption Rate Data
This Iridium Extreme® PTT meets international standards for exposure to
radio waves.
Your satellite phone is designed and manufactured not to exceed limits
for exposure to radio frequency (RF) energy. These limits are part of
comprehensive guidelines and established permitted levels of RF energy
for the general population. The guidelines are based on standards that
were developed by independent scientific organizations through periodic
and thorough evaluation of scientific studies. The guidelines include a
substantial safety margin designed to assure the safety of all persons,
regardless of age and health.
The exposure standard for mobile phones employs a unit of measurement
known as the Specific Absorption Rate, or SAR. Under the guidelines
for this model, the SAR limit is 1.6 W/Kg. Tests for SAR were conducted
in accordance with the European Committee for Electrotechnical
Standardization (CENELEC) and FCC testing procedures using standard
operating positions with the phone transmitting at its highest certified
power level in all tested frequency bands. Although the SAR is determined
at the highest certified power level, the actual SAR of the phone while
operating can be below the maximum value. Before a Phone Model is
available for sale to the public, it is tested to confirm compliance with
the guidelines. The tests are performed in positions and locations
(e.g., at the ear and worn on the body) that conform to a uniform testing
methodology determined by an expert standards body.
The highest SAR level recorded from this product was 1.27 W/Kg which
was below the uncontrolled (e.g., general population) limit. While there
may be differences between the SAR levels of various phones and at
various positions, they all meet the governmental requirements.
The International Agency for Research on Cancer (IARC) concluded in
May, 2011 that that there is limited evidence to suggest a possible link
between RF signals and two specific types of cancer. The IARC’s conclusion
is based on its review of existing studies and information.
The FCC and FDA, however, indicated that there is not sufficient scientific
evidence to support a link between wireless device use and cancer and
that use of wireless phones according to current regulations is safe.
