Hi Everyone -
Unit arrived today.
Didn't have much time tonight - a few notes:
When I started up the system I was unable to initiate network settings or do a firmware update - they were both grayed out in the user menu. This protocol worked:
1) Press Standby/Off
2) Pull the AC able out of the back of the receiver.
3) **Unplug the network(ethernet) cable from the back of the receiver.
4) Wait ~30 seconds or so.
5) Plug the AC cable back in and turn on the receiver.
6) Plug the ethernet cable back into the receiver.
7) Wait about 30 seconds to a minute and then go into setup.
As it happens, no firmware update was needed - unit shipped with the current firmware.
