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. Various 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.

Remove. Thisisaphysicalmeanstoclearthedatabyremovingthememory

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
will be moved (temporarily or permanently) from a secured area to a non-secured
area.

Scrub. This is equivalent to sanitize.

User-modifiable. The memory device can be written to by the user during normal

instrument operation, using the instrument’s user interface or remote control.

Volatile memory. Data is lost when the instrument is powered off.
