Sound reception system

PT 7, Ch 9, Section 3.1.4 states that a sound reception system should be present at the main navigation workstation. The sound reception system control panel is located at the MNC. The sound reception system onboard of M/S MERSol consists of a microphone unit located at the monkey island, that receives sound signals and re-produces these incoming signals electrically inside the bridge. M/S MERSol is required to carry this system onboard, as the bridge is fully enclosed. The sound reception system allows the OOW to perform their lookout duties as per International Regulations for Preventing Collisions at Sea, 1972 and SOLAS 2002(resolution A. 694(17)) revisions.
