＊Some USB storage devices may take long to load, may not be loaded correctly, or may not be correctly fed depending on the device or their content.

＊Onkyo will not be liable whatsoever for any loss or damage of data, or storage failure arising from the use of the USB storage device with this AV receiver. Thank you for your understanding.

Update

1.Connect the USB storage device to your PC.

2.Download the firmware file from the Onkyo website to your PC and unzip.

Firmware files are named in the following way:

ONKAVR＊＊＊＊_＊＊＊＊＊＊＊＊＊＊＊＊.zip

Unzip the file on your PC. The number of unzipped files and folders varies depending on the model.

3.Copy all unzipped files and folders to the root folder of the USB storage device.

Make sure to copy the unzipped files.

4.Connect the USB storage device to the USB port of the unit.

If you connect a USB hard disk drive to the USB port of the unit, we recommend that you use its AC adapter to power it.

If the USB storage device has been partitioned, each section will be treated as an independent device.

5.After pressing RECEIVER on the remote controller, press SETUP.

The Setup menu is displayed on the TV screen.

6.With the cursors, select "8. Miscellaneous" - "Firmware Update" - "Update via USB", and then press ENTER.

You will not be able to select "Update via USB" if there is nothing to update.

7.Press ENTER with "Update" selected to start update.

During the update, the TV screen may go black depending on the updated program. In that case, check the progress on the display of the unit. The TV screen will remain black until the update is complete and the power is turned on again.

During the update, do not turn off, or disconnect and reconnect the USB storage device.

"Completed!" is displayed when the update is complete.

8.Disconnect the USB storage device from the unit.
