Product Usage Instructions
Power Management
Ensure to properly shut down the monitor before disconnecting power to prevent data loss on non-volatile components.
Data Storage
Use appropriate interfaces to store data externally as user access to non-volatile components is restricted.
Maintenance
Avoid tampering with hardware write protection mechanisms to prevent accidental data erasure.
Frequently Asked Questions (FAQ)
Q: What happens if power is removed from the U4025QW Monitor?
A: Volatile components erase data immediately, while non-volatile components retain their data. Primary power loss destroys user data on DDR3 memory, and secondary power loss affects system configuration and time-of-day information.
Statement of Volatility – U4025QW Monitor
CAUTION: A CAUTION indicates either potential dam U4025QW age to hardware or erasure of data and tells you how to avoid the problem.
The U4025QW Monitor contains both volatile and non-volatile components. Volatile components erase their data immediately after power is removed from the component. Non-volatile components continue to retain their data even after power is removed from the component. The following non-volatile components are present on the U4025QW Monitor system board.

CAUTION: All other components on the system board erase data if power is removed from the system. Primary power loss (unplugging the power cord and removing the battery) destroys all user data on the memory (DDR3, 1067 MHz). Secondary power loss (removing the on-board coin-cell battery) destroys system data on the system configuration and time-of-day information.
