Precautions
Important: The LRD 6199SWS was not designed to help you
disobey the law. Safe drivers always obey the posted
speed limit and legal driving methods at all times.
Federal and Local Regulations
The FCC passed the Communications Act in 1934 to give all citizens the
right to receive any type of radio transmission. The same radio
frequencies used by police radar are also used by other devices, such as
automatic door openers, burglar alarms, and some amateur radio
equipment. Since the LRD 6199SWS is just a radio receiver tuned to a
specific portion of the public radio spectrum, it is protected under this act.
Some local, state, and federal regulations may prohibit the use of this
detection device. Please check with authorities regarding the use of this
device before operating it.
