Regulatory Compliance
RF Exposure Information
The radio module has been evaluated under FCC Bulletin OET 65C (01-01) and found to be compliant
to the requirements as set forth in CFR 47 Sections 2.1091, 2.1093, and 15.247 (b) (4) addressing RF
Exposure from radio frequency devices. This model meets the applicable government requirements for
exposure to radio frequency waves.
This wireless phone contains a radio transceiver. The radio transceiver and antenna have been designed
to meet the RF emission requirements for human exposure as specified by the FCC as well as by other
agencies from other countries. These guidelines were developed by the industry based on guidance from
the World Health Organization (WHO). These industry standards have been developed to include
additional safety margins to ensure that the user is exposed to the least amount of RF radiation.
The radio transceiver uses a non ionization type of radiation as opposed to a ionized radiation such as an
X-Ray wave.
The exposure standard for these devices references a unit of measure known as SAR. The limit as set by
the FCC is 1.6W/kg. The tests for this emission level is done in an independent laboratory who employs
test methods and operating positions reviewed by the FCC and other agencies.
Before the phone was placed on the market, the product was tested and certified in accordance with the
FCC regulations to verify that the product did not exceed the FCC SAR requirements.
The highest SAR level measured for this phone was 0.835 W/kg.
Additional information on SAR and RF Exposure can be obtained off the FCC website at:
www.fcc.gov/oet/rfsafety
There is no conclusive proof that these mobile phones are or are not a health risk. The FDA and numerous
researchers are continuing studies of RF radiation and health issues. Additional information on this
subject can be obtained from the FDA web site at: www.fda.gov.
A recent Swedish study concluded that there is no link between the RF energy emitted from mobile
phones and cancer. For more information, refer to the article written by John Boice and Joseph
McLaughlin entitled "Epidemiological Studies of Cellular Telephones and Cancer Risk."
The Cisco 7920 Wireless IP Phone operates at power levels that are 5 to 6 times lower than most standard
cellular, Personal Communications Service (PCS), or Global System for Mobile Communication (GSM)
phones. This lower power coupled with a lower transmitter duty cycle reduces the user's exposure to the
RF fields.
There are several suggested methods to reduce exposure for the user. Among those include:
1.
