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

SRG-150DN/250DN

FEATURES

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

● 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.

● Available MEMORY with 100 DSC transmitting messages (100 MEMORY FILE EDIT)

● Available MEMORY with 100 DSC receiving messages (Distress: 50 messages and Ordinary: 50 messages).

● Installed a built-in internal speaker (Optional external speaker available).
