1. Before Updating

Requirements
- Broadband Internet Access - Cable/DSL Modem - Network Router or Hub

AVR-4308CI AVR-3808CI

- Proper configuration of the Denon A/V component to work on a particular Network Environment - Ethernet Straight Cable for Direct connection to the Network Environment

Recommentations

- If you did not install, or configure, the Denon A/V Component with your Network Environment, please contact your Network Installer/Integrator to assist. - If connecting the Denon A/V Component to your Network Environment for the first time, please read the following sections in the Instruction Manual provided with your component.
Network Audio : AVR-3808/4308CI Instruction Manual, page 20 Network Setup : AVR-3808CI Instruction Manual, page 32, AVR-4308CI Instruction Manual, pages 32-34 Denon does not recommend using Wi-Fi network connectivity when updating/upgrading the components. This is due to the higher possibility of errors in the update/upgrade process from decreased, and/or drop outs of Wi-Fi signals as well as interruption from other nearby Wi-Fi, or other Radio Frequency generating devices.
- Connect the Denon A/V Component directly to your Network Environment via an Ethernet Straight Cable.
- Once the Denon A/V Component is connected and configured properly to your Network Environment, please test that you can receive and listen to Internet Radio stations on the Net//USB input.
This will show you have, at a minimum, a good Internet connection to the component.
Be sure not to 'Power Off' the unit during the update/upgrade process as this will cause a failure in the process.
If this does occur and the unit will not respond normally, please contact Denon USA Customer Service at 1-800-497-8921.
Key Notes on Network Environment Configurations
- Denon A/V Components are not compatible with PPPoE (Point to Point Protocol over Ethernet).
Contact you Internet Service Provider (ISP) to assist in procuring a PPPoE Router.
- Denon A/V Components are not UPnP (Universal Plug and Play) compliant.
This could be an issue with some routers on the market (we have seen this on some NetGear products). You can disable UPnP in the routers setup configuration, however changing this setting can affect the normal operation of other devices on your Network. Contact your Router manufacturer for assistance.

- Some Firewall settings in your network router may not permit the Updating/Upgrading functionality of Denon A/V Components. Contact your Router manufacturer for assistance. - Be sure to disable "VPN" on any PC on your network environment. Company or office network connections will cause a failure in the process.
About System Setup Memory
- The Update Firmware will not reset the system setup configurations of your Denon A/V component.
Note that after downloading and installing the Upgrade Feature Pack (from October 1st, 2008), you will need to recalibrate your system using the Audyssey Room EQ in the component. This is required for you to get the best level of performance from the newly added Audyssey features of Dynamic Volume and Dynamic EQ.
