2. Click Store Changes to store the values to the flash memory.
Click Reject Changes to cancel saving settings. If the parameter
has an edit-copy, the original parameter value is restored. If the

However, the edited value is not stored in the nonvolatile
memory and thus the reboot restores the original value.
