AVR-4308CI FIRMWARE UPDATE AVAILABLE
There are now firmware updates available through our DPMS (Denon Product Management Server) for AVR-
4308CIs – USA and Canada models only (please verify serial numbers and firmware version numbers below).
These updates allow Denon to address certain operating issues, as well as adding new features and functionality. A
previous update was available only for limited number of units with operational issues, however for many AVR-
4308CIs to complete any current or future updates, the original update is included for those units that did not it from
the DPMS server directly or was applied at production, again please verify serial numbers and firmware version
numbers below.
We ask you thoroughly read and understand this entire document before starting any update procedure with your
AVR-4308CI. Thank you.
Firmware Update #1 Improvements:
1. In the GUI, under ‘Network Info’, the information was displayed incorrectly as the columns did not match up.
2. Auto Setup did not have the ability to handle a 6.1 speaker configuration, so it would lock up.
3. The Display screen would go blank shortly after showing the GUI.
4. RS-232/IP Protocol Fixes
a. Could not perform direct access to XM stations with the TFXMnnn command.
b. No response for commands, PSBAS, PSTRE OR PSxxx from the Ethernet port.
Serial Number Start of Factory Updated AVR4308CIs: xxxxx03536 (only need the last 5 digits)
