WASHINGTON — Simulated wireless alert tones used in a “Jimmy Kimmel Live” skit making fun of a presidential alert test have cost ABC $395,000 in civil fines with the Federal Communications Commission.

In another action on Thursday, AMC Networks agreed to pay a $104,000 fine for using an alert tone in a February episode of “The Walking Dead.” The commission also fined Discovery’s Animal Planet channel and Meruelo Radio Holdings smaller amounts for similar violations.

The use of the emergency alert system or wireless emergency alert tones is barred by F.C.C. rules “to avoid confusion when the tones are used, alert fatigue among listeners and false activation of the system by the operative data elements contained in the alert tones,” the agency said.

Discovery agreed to pay a $68,000 civil penalty because an episode of Animal Planet’s “Lone Star Law” contained an actual wireless emergency alert tone. The crew was filming Texas game wardens after Hurricane Harvey and caught the tone of a real wireless alert.
