DOS format.)

personal computer.
(2) Save the data of the CF Card with your personal computer.

3.2.9 USB Cable Clamp Attachment/Removal
This clamp is used to prevent the USB cable connected to the USB Host Interface on the bottom of the PS-A
unit from being unplugged due to vibration or other causes.
„ Attachment
(1) Place the PS-A unit face-down on a flat surface as shown below. Your PS-A unit has four USB
connectors.
• Be sure to protect the display surface to prevent damage during the operations.
• When using two or more USB ports, be sure to first connect one USB cable to the lower
USB connector, and then connect the second USB cable to the upper USB connector.
• When using only one of the USB ports, be sure to use the lower USB connector. This
allows you to securely clamp the USB cable in the cable clamp.
