It complies with GMDSS carriage requirements for safety and general communications
The FM-8500 offers simplex/semi-duplex voice communications on all ITU channels in the 156-174 MHz VHF band. Other standard features are Dual Watch and Multiple Watch functions which allow a watch on CH 16 and another selected frequency.
Full Class A DSC functions are provided for distress
alert transmission and reception, as well as the general call formats: Individual Telephone, All Ships, Group and Area Call. Distress alert can be readily transmitted but an arrangement is provided to prevent an accidental activation.
The FM-8500 maintains a continual watch on CH 70 even while you are using another VHF channel. Upon receiving an incoming DSC message the FM-8500 gives aural and visual alarms.
The compact cabinet allows a flexible and space- saving installation on a navigation console or at the conning position.
