Preface
Terms
The following terms may be used in this document:
Clear. This removes data on media/memory before reusing it in a secured area. All reusable memory is cleared to deny access to previously stored information by standard means of access.
Erase. This is equivalent to clear.
Media storage/data export device. Any of several devices that are used to store or export data from the instrument, such as a USB port.
Nonvolatile memory. Data is retained when the instrument is powered off.
Power off. Some instruments have a “Standby” mode, in which power is still supplied to the instrument. For clearing data, putting the instrument in
Standby mode does not qualify as powering off. For these products, you must either push a rear-panel OFF switch or remove the power source from the instrument.
Remove. This is a physical means to clear the data by removing the memory device from the instrument. Instructions are available in the product Service
Manual.
Sanitize. This eradicates the data from media/memory so that the data cannot be recovered by other means or technology. This is typically used when the device is moved (temporarily or permanently) from a secured area to a nonsecured area.
User-modifiable. The user can write to the memory device during normal instrument operation, using the instrument interface or remote control.
