Do not connect USB devices having a rating above this, since this can cause damage to the instrument itself.  Connecting USB device • When connecting a USB device to the USB [TO DEVICE] terminal, make sure that the connector on the device is appropriate and that it is connected in the proper direction. NOTICE • Avoid connecting or disconnecting the USB device while executing playback/recording and file management operations (such as Save, Copy, Delete and Format), or when accessing the USB device. Failure to observe this may result in "freezing" of the operation of the instrument or corruption of the USB device and the data. • When connecting then disconnecting the USB device (and vice versa), make sure to wait a few seconds between the two operations. NOTE • When connecting a USB cable, make sure that the length is less than 3 meters. Using USB Flash Memory By connecting the instrument to a USB flash memory, you can save data you've created to the connected device, as well as read data from the connected device. NOTE • Although CD-R/RW drives can be used to read data to the instrument, they cannot be used for saving data.  The number of USB flash memory to be used Only one USB flash memory device can be connected to the USB [TO DEVICE] terminal.  Formatting USB flash memory You should format the USB storage device only with this instrument (page 58). A USB flash memory formatted on another device may not operate properly. NOTICE • The format operation overwrites any previously existing data. Make sure that the USB flash memory you are formatting does not contain important data.  To protect your data (write-protect) To prevent important data from being inadvertently erased, apply the write-protect provided with each USB flash memory. If you are saving data to the USB flash memory, make sure to disable write-protect.  Turning off the instrument When turning off the instrument, make sure that the instrument is NOT accessing the USB flash memory by playback/recording or file management (such as during Save, Copy, Delete and Format operations). Failure to do so may corrupt the USB flash memory and the data. Reference 56 PSR-E443 Owner's Manual
