Change-Settings Log and Setup Files When Recording (Memory Sampling) Is

Not in Progress

When you change the settings, the changes are logged in the change settings log and

the operation log. At the same time, a setup file is saved to the CF card. The date, user

name, and affected setup file name are recorded in the change settings log, which is

saved to the CF card.

For information about the display, see section 2.4.

Note

Make sure that the CF card is inserted when you change the settings. When the DX is unable

to save a setup file, it displays an error message, and you will be unable to finish the process of

changing the settings.

Logged Operations

file loading and setting initialization are also logged.

settings have changed. If a CF card is not inserted when the DX tries to save a setup

le, an error occurs.
