What occurs when the AN/PRC-163 radio is first powered on?

When the AN/PRC-163 radio is first powered on, it performs a self-test. This self-test is a critical initialization process that ensures the functionality and integrity of the radio's components before it is used for communication. During this self-test, the radio checks its internal systems and configurations, verifying that everything is operating correctly and is ready for use.

The purpose of this self-test is to detect any potential issues that could affect communication performance or reliability. By confirming that all systems are functioning as expected, operators can have confidence in the equipment's operational readiness and avoid situations where malfunction could jeopardize communications in tactical environments.
