Subject: Statement of Volatility – Dell S518WL Projector
To whom it may concern:
The purpose of this document is to certify that Dell’s S518WL projector 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 S518WL projector 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 Dell S518WL
