SAVING DATA （データの保存）
Saving and backing up your data
• DRAM data is lost when you turn off the power
to the instrument. Save the data to external
USB storage device.
• Never attempt to turn off the power while data
is being written to Flash ROM (while a “Please
keep power on” message is shown). Turning
the power off in this status results in loss of all
user data and may cause the system to freeze
(due to corruption of data in the Flash ROM).
This means that this instrument may not be
able to start up properly, even when turning the
power on next time.
Saving factory preset data
• When you save your original data to flash
ROM, the factory preset data in some area of
the
fl ash ROM will be lost. Before saving your
original data, be sure to save the factory preset
data to external USB storage device.
Backing up the external USB storage device
• To protect against data loss through media
damage, we recommend that you save your
important data onto two USB storage devices.
