Subject: Statement of Volatility – Dell S718QL Projector
To whom it may concern:
The purpose of this document is to certify that the Dell S718QL 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 S718QL 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.
