What does "Reserve Source of Energy" refer to?

"Reserve Source of Energy" refers specifically to the supply of electrical energy that is designated to operate radio installations for Distress and Safety communications. This is crucial in emergencies where reliable communication is essential for the safety of life at sea or during distress situations. The reserve energy ensures that essential communication equipment remains operational when regular power sources may be compromised or unavailable, thus facilitating effective response measures to emergencies.

In the context of maritime operations, maintaining a functional communication system during distress is vital, as it allows for the transmission of urgent messages to rescue services and ensures that the crew and passengers on board can communicate their situation effectively. The integrity of the reserve energy supply is vital, underscoring the importance of preparedness in maritime safety protocols.
