Safety information for the Lexus Link System
Important! Read this information before using the Lexus Link System.■Exposur
e to radio frequency signals
The Lexus Link System installed in your v
ehicle is a low power ratio trans-
mitter and receiver. When the engine sw itch is in the “
ON” position, it
receives and also sends radio frequency (RF) signals. 
In August 1996, the Federal Communications Commission (FCC)
adopted RF e
xposure guidelines with safety levels for mobile wireless
phones. Those guidelines are consistent with the safety standards previ -
ously set by both U.S. and international standards bodies.
● ANSI (American National Standar
ds Institute) C95.1 [1992]
● NCRP (National Council on R
adiation Protection and Measurement)
Report 86 [1986]
● ICNIRP (International Commis
sion on Non-Ionizing Radiation Pro -
tection) [1996]
Those standards were based on comp r
ehensive 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 S
ystem complies with the FCC guidelines in
addition to those standards.
