Statement of Volatility 
Clearing user and site-specific data from a LinkRunner AT Tester



The LinkRunner AT 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 user and site-specific data previously stored in memory. The sanitation processes for each memory type are provided.
