The SRG-1150DN/1250DN service manual provides a thorough understanding of the internal electronics.
To satisfy GMDSS mandates, an isolated, dedicated receiver scans the six designated DSC distress frequencies continuously. It utilizes a rapid 2-second scanning sequence per frequency, halting only when a 100-baud dot pattern is discovered. Initial Setup & Software Clear Routines
