According to 47 CFR Section 90.403 - General Operating Requirements, licensees shall take reasonable precautions to avoid causing harmful interference. Which statement best reflects this requirement?

• A. To avoid harmful interference
• B. To report training requirements
• C. To maximize power
• D. To share frequencies

Answer: (A)

The core idea is that licensees must operate in a way that prevents harming other users of the spectrum. 47 CFR 90.403 charges licensees with taking reasonable precautions to avoid causing harmful interference to other stations and services. In practical terms, this means staying within your authorized parameters (correct frequency, power, and emissions), keeping equipment in good working order, coordinating when necessary, and acting to stop or reduce transmission if interference is detected. So the statement that best reflects this requirement is simply to avoid harmful interference. The other options miss the fundamental obligation: reporting training requirements isn’t about how you operate your radio, maximizing power increases the risk of interference, and sharing frequencies requires proper coordination and authorization beyond the general precaution.
