Which of the following is NOT required when preparing classified information for transmission?

When preparing classified information for transmission, several requirements are in place to ensure security and accountability. Disabling all electronic devices is not a requirement in this context, as it does not directly pertain to the handling or documentation of classified material.

In contrast, documenting the sender's information is essential for tracking and accountability, as it provides a clear record of who is responsible for the transmission. A receipt for the material is also crucial since it verifies that the classified information has been received by the intended recipient, thus maintaining a chain of custody. Completing all necessary forms ensures that all relevant information is formally recorded, further safeguarding the classified material and adhering to protocol.

These protocols are designed to minimize the risk of unauthorized access or loss of classified information, emphasizing the importance of proper documentation and verification processes in the transmission of sensitive materials.
