SRG-150DN/250DN

Description

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 realisation.

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).
