Power States

This section describes the three power states of Hydrus: High Power, Low Power, and Shipping Mode. Detailed are the activation and selection processes for each state, in addition to associated safety precautions required for maintaining optimal performance. Proper understanding and management of these power states are vital to the functioning and operation of Hydrus in different underwater environments.

High Power

Overview

When set to High Power, Hydrus is fully functional and gives users complete access to all its applications. When operating in water, Hydrus MUST be in this power state.
