Denon AVR-X3800H User Manual

Restoring the firmware to the factory defaults
When the unit or the network functions do not work properly, operation may be improved by restoring the firmware to the factory defaults.
Do this when the unit still does not work properly even after trying the steps for “Resetting factory settings” or “Resetting network settings”. (v p. 278,
279)
After the firmware is restored, various settings are reset to the default settings. Configure the network settings and update the firmware again.
