The Denon 3808ci is an awesome receiver for the mid level home audio user. I use them to power two different setups in my house and try to update the firmware once a month by using the following instructions.
- Open Menu: Click menu on your remote control
- Manual Setup: Use the up or down arrow to navigate to the Manual Setup menu.
- Options Setup: Use the up or down arrow to navigate to the Options Setup menu.
- Firmware Upgrade: Use the up or down arrow to navigate to the Firmware Upgrade menu and click start upgrade.
If there is no upgrade available then the system will let you know that an upgrade is not available for the Denon 3808ci. If there is on available it will automatically start to upgrade. Typically it takes about 70 to 90 minutes to upgrade the 3808ci so don’t attempt an upgrade right before wanting to use the receiver. Another thing to note is the fact that your Denon receiver must be on your local network and have access to the Internet to perform the upgrade. It seems like Denon puts out upgrades for these receivers fairly often so check for firmware updates often from Denon to keep your receiver running the latest firmware.
