Update via USB Storage

Note: Please remove the wired/wireless connection before updating through USB. Prepare a USB storage device such as a USB flash memory stick. You need at least 128 MB of available space to update the firmware. Please unpack the ZIP file onto an empty USB Stick that has been formatted with the FAT file system.

We hope you enjoy the improved functionality this update provides to your AV Receiver.

Precautions for the Firmware Update

Please read the update instructions carefully before beginning. The firmware update should take up to 30 minutes. Once the update begins, do not turn off the power supply to the A/V receiver until it is time to restart it.

Depending on network conditions, a firmware update via a network may take more than one hour or even fail to finish. If the update is not completed within two hours, turn off the power supply by pushing the ON/STANDBY button and then try updating again from the beginning.

Updating the firmware and adjusting the settings will be done automatically, but may take some time to complete. Please follow the procedures as instructed when you update. Note that the update may fail, or cause problems for your A/V receiver, if you do any of the following:

• Pull out the A/V receiver's power cord;
• Interrupt the power supply to the A/V receiver (e.g. if the breaker is tripped or if there is an electrical outage);
• Insert or remove the LAN cable from a device in your network when updating over a network;
• Insert or remove a USB memory device from the A/V receiver when updating via USB;
• Operate components connected to the A/V receiver via HDMI, such as a TV or a recording device.

If your A/V receiver is damaged for any of the reasons above, an Onkyo service center will repair the unit for a fee.

If you see "No Update" on the front panel immediately after you have started the firmware update process, you have the latest firmware. In this case, it is not necessary to do this update.
