The FCC has established the detailed body-worn SAR requirements and has established that these requirements have been met with the specific belt-clip/holster provided with the handset. Other belt-clip/holsters or similar accessories that have not been tested may not comply and therefore should be avoided. Regulatory Compliance and Safety Information 57 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 47 CFR 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 an 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. 58 78-18795-01 The highest measured SAR levels for the phones are these: • Cisco Unified Wireless IP Phone 7920 is 0.54 W/kg. • Cisco Unified Wireless IP Phone 7921G is 0.51W/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 Unified Wireless IP Phone 7920 series 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. Regulatory Compliance and Safety Information 59 There are several suggested methods to reduce exposure for the user. Among those include: 1. Using a hands-free handset to increase the distance between the antenna and the head of the user. 2. Orienting the antenna away from the user.
