After multiple enforcement actions totaling hundreds of thousands of dollars in penalties against importers and retailers of LED signs last year, it appears that the message has not been fully received. To the contrary, the FCC is back at it in enforcing its equipment marketing rules against importers and retailers of LED signs in 2019. In a recent Enforcement Advisory, the FCC again warned companies marketing noncompliant LED displays that they may be subject to costly investigations and significant monetary penalties. As we previously reported, these warnings should put all importers and retailers of LED signs – many of whom may not know FCC rules apply to them – on notice that their products should be authorized, properly labeled, and contain the required user disclosures before being marketed in the United States. The FCC often uses Enforcement Advisories to set the stage for future enforcement action and the agency appears poised to move forward with another wave of enforcement actions in the coming months. It is therefore critical that companies assess their equipment marketing compliance procedures now to avoid Commission enforcement later.
