Connecting a USB Flash Drive By connecting a USB flash drive (sold separately) to the [USB TO DEVICE] terminal, you can save data created on the instrument, such as User Songs and parameter settings. The saved data can be recalled to the instrument for future use. NOTICE You should use an AC adaptor when executing USB flash drive operations. Battery power might not be reliable enough to last through these crucial operations. When you try executing certain functions, the "UseAdpt" indication might appear and the selected function cannot be executed unless an AC adaptor is used.. Precautions when using the [USB TO DEVICE] terminal This instrument features a built-in [USB TO DEVICE] terminal. When connecting a USB device to the [USB TO DEVICE] terminal, be sure to observe the following. NOTE For more information about the handling of USB devices, refer to the owner's manual of the USB device.  Compatible USB devices • USB Flash Drive Other USB devices such as a USB hub, computer keyboard or mouse cannot be used. Compatible USB devices are listed under "Materials/ Data" on the following website. Be sure to check this website before purchasing devices. Support/inquiries: https://download.yamaha.com/ Although USB devices 1.1 to 3.0 can be used on this instrument, the amount of time for saving to or loading from the USB device might differ depending on the type of data or the status of the instrument. NOTICE The rating of the [USB TO DEVICE] terminal is a maximum of 5 V/500 mA. Do not connect USB devices that have a rating above this, since this can cause damage to the instrument itself.  Connecting a USB device Insert a plug that matches the shape of the [USB TO DEVICE] terminal, and pay attention to its vertical orientation. 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 might 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. • Do not use extension cables to connect USB devices; connect the device directly. Using a USB Flash Drive By connecting the instrument to a USB flash drive, you can save data you've created to the connected device, as well as read data from the connected device.  Number of USB flash drives that can be used Only one USB flash drive can be connected to the [USB TO DEVICE] terminal.  Formatting a USB flash drive You should format the USB flash drive only with this instrument (page 58). A USB flash drive formatted on another device might not operate properly. NOTICE The format operation overwrites any previously existing data. Make sure that the USB flash drive you are formatting does not contain important data.  To protect your data (write-protect) Some USB flash drives have a write-protect function to prevent accidental erasure of data. To prevent important data from being inadvertently erased, apply the write-protect provided with each USB flash drive. If you are saving data to the USB flash drive, 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 drive by playback/recording or file management (such as during Save, Copy, Delete, and Format operations). Failure to do so might corrupt the USB flash drive and the data. 56 PSR-E473, PSR-EW425 Owner's Manual
