1. EQUIPMENT OVERVIEW
1.1 Functions
This equipment includes VHF radiotelephone, Class-A DSC and DSC watchkeeping receiver
required as the Global Maritime Distress and Safety System (GMDSS). It is designed as a
compact, integrated unit that does not require a cable to connect the transceiver and controller;
plus the controller is also compact and lightweight. It is intended for easy installation in
non-regulated ships under 300 tons, more so than regulated ships (IMO regulated passenger
ships and cargo vessels over 300 tons).
This equipment has standard functions that include regular transmissions and DSC (digital
selective calling) for distress transmissions, as well as functions to playback and record
transmissions in real-time and an easy-to-operate self-diagnosis function. Additionally, various
optional functions are available, such as a public address function to output speech through the
handset by connecting an external speaker; an intercom function for communication from the main
unit to controllers and between controllers; and a DSC calling function that uses other ships'
information acquired by connecting your own ship's automatic identification system (AIS).
