In Windows Explorer, you cannot display [Thumbnails] (Windows 2000).
In Windows 2000, if you display the contents of a memory card in Windows Explorer, and change
the display to [Thumbnails] on the [View] menu, the images may not display and the computer may
freeze. This is a problem that occurs with USB card readers in general, and not just with this
machine.
If you want to change the display to [Thumbnails] in Windows Explorer, set the <CARD PROTECT>
setting to <OFF> ( p. 4-15). Then turn the machine off and on again.
The memory card is recognized as a drive other than [Removable Disk].
Did you start your computer with a memory card inserted in a card slot?
Depending on your computer, this may occur if you start your computer with a memory card
inserted in the machine.
Remove the memory card and restart your computer.
If nothing displays in the LCD (if there is no power)
When you connect the power cord to the machine and wall outlet, and press [ON/OFF (1 sec.)],
the machine powers up and a message is displayed in the LCD.
While the Alarm light blinks, the machine is initializing and you will not be able to use it. Wait
until the Alarm light stops blinking.
If nothing is displayed in the LCD, make the checks in the following order until something is
displayed.
1. Is the power cord correctly connected?
Securely connect the power cord to the machine and wall outlet.
2. Have you pressed [ON/OFF (1 sec.)]?
The machine will power up and the LCD will show a message when you connect the power cord and
press [ON/OFF (1 sec.)].
3. Check that the wall outlet is working normally.
Connect another electrical appliance to the wall outlet and check whether the wall outlet is working
properly.
4. Connect the power cord directly to the wall outlet.
Disconnect the power cord from any table taps, OA taps or extension cords and connect directly to the
wall outlet. If the machine powers up when the power cord is connected directly, the table taps, OA
taps or extension cords are probably defective and should be replaced.
If they have a power switch, turn it on.
5. Check that the power cord is not defective.
Either replace the power cord with another, or using a tester, check whether the cord is defective.
