Press the key and navigate to the Initial System Settings screen. Select the MMSI / Ship ID Entry line item.
Connect the between the radio and the antenna. Use high-quality 50Ω coaxial cable for all RF connections 3. Power Wiring Connect to DC 24V battery power. If using AC power , wire the AC/DC power supply/charger
: Connect a standard inline 50-ohm dummy load wattmeter to check the transmission levels. Confirm the power settings adjust correctly across all three power modes: High (150W), Mid (100W), and Low (50W).
This is the most critical operation for safety at sea.
The Maritime Mobile Service Identity (MMSI) is an alphanumeric identifier critical for DSC operations. By law, this number can only be entered once. Power on the transceiver by pressing the key. samyung srg-1150dn installation manual
Ensure the AC breaker and backup DC battery switches are turned .
Plug the multi-core control cable into the matching tuner port on the radio. This cable supplies the 24V switching logic and feedback signals that manage the tuning relays. Data Terminals & Printers
: To prevent magnetic interference, maintain a minimum distance of 2.4m from a standard compass and 1.5m from a steering compass.
The is a highly reliable MF/HF radio transceiver explicitly engineered to meet Global Maritime Distress and Safety System ( GMDSS ) requirements. Delivering 150 watts of output power, this compact marine communication unit integrates Digital Selective Calling (DSC) and Narrow Band Direct Printing (NBDP) functions to facilitate medium- and long-range emergency and commercial maritime communications.

: Interface the data terminal using the specialized system bus cable. Connect the SPR8630 keyboard to the dedicated front-facing USB/DIN port on the terminal casing.
: Post an RF radiation hazard sign near the base of the whip or wire antenna to caution personnel against touching it while the radio is transmitting. Post-Installation Diagnostics and Testing
) for longer distances to prevent excessive voltage drops during 15A transmission peaks. Use high-quality 50Ω coaxial cable for all RF connections 3
Use premium 50-ohm coaxial cable, such as RG-213 or 8D-FB, for the run between the main unit and the ATU.
Once physical integration and cabling verification are complete, the unit can be initialized through its technician settings menu. Entering the Ship MMSI ID Number
Check ground connection and antenna cable integrity.
