SSE Messages

SSE (System Security Error) — error codes defined by the IHO S-63 standard. Errors and warnings that occur when working with charts, licenses, and certificates are recorded in the Installation Logbook. Some errors, such as SSE-25 and SSE-27, are also displayed in the permanent indication area.

Where SSE Messages are Displayed

SSE error information is displayed in:

**Installation Log** — during ENC operations
**Notification Area** — when critical errors occur
**ENC Collection Report** — for chart status analysis
