There is no conclusive proof that these mobile phones are or are not a health
r
isk. 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 ther
e 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
t
hat 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.
