Problem
The USB storage device is not
recognized by the instrument.
The USB storage device has hung
up (stopped).
The folder name does not change.
Cause
The USB storage device may not be
recognized by the instrument
depending on the timing of the
device connection or the setting of
the [SELECT] switch.
The USB storage device is not
compatible with the instrument.
The USB storage device does not
operate properly.
A maximum of 13 characters from a
folder name can be displayed.
Therefore, if several folders have the
same 13 characters at the start of
their names, it will appear that they
do not change when the C [–][+]
buttons are pressed.
Troubleshooting
Solution
Disconnect the USB storage device
and connect it again and select a
device using the [SELECT] switch.

you try to engage these modes
before connecting the USB storage
device, press the [EXIT] button to
exit the mode and re-engage the
