ICOM IC-GM651 VHF DSC
VHF / DSC

Meets GMDSS requirements The IC-GM651 is a compact VHF radio telephone with Ch 70 watchkeeping receiver and CLASS A DSC functions. The radio meets the GMDSS requirements as required for SOLAS regulated commercial vessels engaging in international voy- ages. With the optional PS-250 DC-DC power supply, the IC-GM651 also meets MED 96/98/EC, “wheelmark” require- ments for European merchant ship

Built-in ITU Class A DSC An independent DSC receiver constantly watches Ch 70 VHF DSC channel, while using another channel. The Class A DSC provides automated distress and safety communication. Re- ceived distress signals can be relayed to a coast station. A total of 100 MMSI IDs can be stored with a 10-character name. PS-250 DC-DC power supply and PS-240 AC-DC power supply available The optional PS-250* DC-DC power supply offers stable 12.5V power to the IC-GM651 from a 12V/24V DC (10.8–31.2V DC) power source and provides floating ground connection. The optional PS-240 AC-DC power supply unit is also avail- able with the PS-250. When connecting a storage battery to the PS-240, the PS-240 automatically switches the power source for backup, even if the AC power fails. * The PS-250 MUST BE USED with the IC-GM651 for MED certification compliance. HS-98 Handset and/or HM-126RB-1 speaker-microphone selectable The IC-GM651 gives you the choice of a handset and/or speaker-microphone. The handset provides clear audio even in noisy environments. The speaker-microphone has a re- mote control function to control operating channel and trans- mit power with dedicated buttons. Rugged and waterproof construction* for professional use To withstand harsh marine environments, the IC-GM651 has been tested to and passed the rigorous salt spray test. In ad- dition, the front panel of the IC-GM651 has waterproof pro- tection equivalent to IPX7 which withstands 1m depth of water for up to 30 minutes. * The front panel of the IC-GM651 only.
