    HVG MARINE ELECTRIC EQUIPMENT 0051: 150W & 250W MF/HF Digital SSB Radio Telephone

    This is an MF/HF SSB (single side band) radiotelephone with a built-in DSC/watch receiver. The built-in DSC/watch receiver produces and receives digital selective calls for quick and efficient establishment of distress, urgency, safety and routine communications with other ships and coast stations than install any MH/HF DSC facilities. Data is displayed on a large, easy-to-read backlit LCD. Operation is simplified by the use of few keys and easy-to-follow menus. Besides, an NBDP (narrow band direct printing) Terminal Unit is optionally available.

    Features:

    • Fully meets the following regulations: IMO A.694(17), IMO A.804(19), IMO A.806(19), IMO A. 813(19), IMO MSC 68(68), IEC 60945, IEC61907-3/8/9, IEC-61162-1, EIV-300/333, ITU-R M.493-10, M.541-8, M.1082-1, EN 300 373, EN300 338, EN300 033, and ETS 300 067
    • PSTN(public switched telephone network) capability standard
    • Distress, safety and routine calling
    • Scanning of DSC frequencies for distress and general calls on MF/HF
    • File editing capability for readiness in case of emergency
    • Automatic error-free telex communications and distress message in compliance with GMDSS requirements
