1 INTRODUCTION
The RM2042 VHF receiver modem, has been developed to fullfil the international requirements stated
by IMO, in the Global Maritime Distress and Safety System,known as GMDSS.
TheRM2042isthefirstself-containedreceiver-modemonthemarket,whichincludesaseparatereceiver
with continous watch on calling ch. 70, and a fullfeatured CLASS A modem for reception and generation
of all types of calls.
Combined with a VHF in the compact 2000 program, a complete fully automatic VHF-communication
system can be build. Furthermore the units can be combined with other compact 2000 units to form a
complete GMDSS installation.
TheRM2042combinestheIMOrequirements onsafety,withalotof userconvenientfeaturestobeused
in normal VHF-communication. And of course a high security scrambler can be combined with the
system.
This advanced communication controller uses a lot of front end technologies, including a complete new
range of components as well as the well known mechatronic design. Resulting in a high quality product,
able to withstand the harsh environmental conditions present at sea.
In spite of all the precautions taken in the design of this unit, a regular service and maintenance is
recommended, to increase unit life-time and user safety.
