DESK Type 150/250W MF/HF DSC, NBDP SYSTEM GMDSS Samyung

DESK Type 150/250W MF/HF DSC, NBDP SYSTEM

SRG-150DN/250DN

FEATURES

? Compliant with ITU (ITU-R M.493-14, M.541-10), IMO and GMDSS standard.

? Improvement of sound quality, which applied with new conceptual SYNTHESIZE technology and noise-free realization.

? Implements a digital filter using DSP, eliminates external noise and noise generated by inside of the ship, significantly improves call quality.

? Compact size with simplified key and dial for the maximized and easy operations.

? Designed as one-unit DSC and W / K receiver built in the desktop of transceiver.

? Installed with 10.4-inch color LCD for easy message reading of NBDP TERMINAL.

? Each function and frequency are easy to read with the adoption of liquid crystal display.

? Available with quick scan function for the variation of transmission output, frequencies and channels by group or individually.
