Safety information for the Lexus Link System
Important! Read this information before using the Lexus Link System. ■Exposure to radio frequency signals
The Lexus Link System installed in your vehicle is a low power ratio trans-
mitter and receiver. When the ignition switch is in the “ON” position, it
receives and also sends radio frequency (RF) signals.
In August 1996, the Federal Communications Commission (FCC)
adopted RF exposure guidelines with safety levels fo r mobile wireless
phones. Those guidelines are consistent with the safety standards previ-
ously set by both U.S. and international standards bodies.
● ANIS (American National Standards Institute) C95.1 [1992]
● NCRP (National Council on Radi ation Protection and Measurement)
Report 86 [1986]
● ICNIRP (International Commission on Non-Ionizing Radiation Pro-
tection) [1996]
Those standards were based on comp rehensive and periodic evaluations
of the relevant scientific literature. Over 120 scientists, engineers, and
physicians from universities, government health agencies, and industry
reviewed the available body of resear ch to develop the ANSI Standard
(C95.1).
The design of the Lexus Link System complies wi th the FCC guidelines in
addition to those standards.
