How To Reprogram Your MFHF

• 1. Identify your radio model: Each brand (e.g., Furuno, ICOM, JRC) has a unique programming interface.
• 2. Access programming mode: This is often done through a protected technician menu or PC software.
• 3. Use the right tools: Most MF/HF radios require a serial cable and vendor-specific programming software.
• 4. Update frequencies: Add, delete, or modify stored frequencies to meet updated communication requirements.
• 5. Modify MMSI and DSC settings: Essential for digital communication and safety alerts.
• 6. Save and validate: Confirm your settings and run a diagnostic or loopback test to ensure functionality.

If your vessel participates in GMDSS, MF/HF programming must comply with IMO and SOLAS regulations. Always document your changes and, if unsure, contact experts like SEANAV to avoid operational errors or non-compliance fines.
