*Question E0A09:
Which of the following types of equipment are exempt from RF exposure evaluations?*  

*Correct Answer is  C: Hand-held transceivers sold before May 3, 2021*  

### AI Response: (may contain errors)  

The correct answer to the question about which types of equipment are exempt from RF exposure evaluations is:

**C: Hand-held transceivers sold before May 3, 2021.**

### Explanation of the Correct Answer:
- **Hand-held transceivers sold before May 3, 2021** are exempt from RF exposure evaluations because they were manufactured under older regulations that did not require such evaluations. The FCC established this exemption to avoid burdening manufacturers and users of older equipment with new compliance requirements.

### Explanation of the Incorrect Answers:
- **A: Transceivers with less than 7 watts of RF output**  
  This choice is incorrect because the power output alone does not determine exemption from RF exposure evaluations. While lower power levels may reduce exposure risk, they do not automatically exempt the device from evaluation requirements.

- **B: Antennas that radiate only in the near field**  
  This choice is incorrect because near-field radiation can still pose exposure risks, especially at close distances. Therefore, antennas must still be evaluated for RF exposure regardless of their radiation pattern.

- **D: Dish antennas less than one meter in diameter**  
  This choice is incorrect because the size of the dish antenna does not exempt it from RF exposure evaluations. The potential for RF exposure depends on various factors, including the power level and the operating frequency, not just the physical dimensions of the antenna.

### Useful Rules of Thumb:
- RF exposure evaluations are generally required for all equipment unless specifically exempted by regulations.
- Always check the latest FCC rules and guidelines for any updates regarding RF exposure evaluations and exemptions.
