Statement of Volatility
Clearing a Network Identity from a
OneTouch AT Network Assistant
The OneTouch AT Network Assistant incorporates volatile and non-volatile memory. Volatile memory is memory whose contents are lost when power is removed. Non-volatile memory is memory whose contents are retained when power is removed. Both memory types can be sanitized to remove data previously stored in memory. The sanitation processes for each memory type are provided.
