Question 116 Deck Safety

The correct answer is C) The manufacturer's operating manuals. The manufacturer's operating manuals are the authoritative source for information on the proper operation of GMDSS radio equipment. These manuals provide detailed instructions from the equipment manufacturer on how to correctly use and maintain the GMDSS radios. This is the primary reference that GMDSS radio operators should consult to ensure they are operating the equipment properly and in accordance with the manufacturer's specifications. The other answer choices are not the correct primary reference for GMDSS radio operation. While SafetyNET channels (A) and ITU lists (D) may provide supplementary information, the manufacturer's own operating manuals are the definitive source. 47 CFR Part 80 (B) covers FCC regulations for maritime radio, but does not provide the level of detail needed for proper GMDSS radio operation.
