10 Notes on turning off the power
In the factory settings, the Write Filter function is set as disable. When data is written in the devices (except
CF card) that are not protected by the Write Filter, turning off the power may cause damage of the data.
 When the Write Filter is enabled
It is not necessary to perform the shutdown procedure. Confirm that no data is being written into another
device, follow the steps of Safely Remove Hardware, and then turn off the power. However, the OS setting
changed and the data written to the CF card during the time will be canceled and lost when the power is turned
off.
<How to confirm that no data is being written into another device>
Hard Disk : Confirm that the LED of the IPC Series is turned off.
USB Device/PCMCIA : Confirm that no data is written on user's applications.
 When the Write Filter is disabled
It is necessary to perform the shutdown procedure. Because the write protection is not enabled, the OS setting
changed and the data written to the CF card will be enabled.
