Statement of Volatility – Dell UltraSharp U3417W Monitor

CAUTION: A CAUTION indicates either potential damage to hardwar e or loss of data and tells you how to avoid the
problem.

The purpose of this document is to certify that the Dell UltraSharp U3417W monitor will not save,
retain, or reproduce a signal to any internal or external component after power has been removed and
reapplied to the unit.

The Dell UltraSharp U3417W monitor contains both volatile and non-volatile (NV) memory ICs. Volatile
memory(s) lose their data immediately upon removal of power. Non-volatile memory ICs continue to
retain their data even after the power has been removed. However, no input video data is written into
these memory ICs during operation.

List below contains volatile and non volatile memory ICs used in the Dell UltraSharp U3417W monitor.
