The Federal Communications Commission (FCC) recognized the need for and adopted rules to control the harmful interference to radio communications services from these devices. During the rulemaking process the Coast Guard provided comments and recommended an advisory label for CFLs / RF lighting devices warning users about potential interference to communication services and particularly with respect to devices capable of producing emissions in the 0.45-30 MHz band. As a result, the FCC required manufacturers of CFLs to provide an advisory statement, either on the product packaging or with other user documentation, similar to the following: “This product may cause interference to radio communications and should not be installed near maritime safety communications equipment or other critical navigation or communication equipment operating between 0.45-30 MHz.”
The Coast Guard has learned that CFLs have been installed on the navigation bridges of vessels and in other places capable of causing radio communications interference. Marine inspectors, vessel owners and operators ** should be aware of this potential safety hazard ** and take proper action as needed.
