IMPORTANT NOTES

Dirac files:

Firmware updates clear any Dirac calibration settings that are currently uploaded to the AVR/Maestro. Make sure you have access to the saved Dirac calibration file on your computer so you can upload back to the AVR/Maestro once the firmware update has completed.

Store a secure backup of the AVR/Maestro settings

Press and hold the MENU button on the front panel for about 4 seconds, the engineering menu will be displayed. Scroll down to and select Store Secure Backup > select Enter Pin (it will display the default pin 0000) and press OK on the remote control or Select on the front panel.

To check the current firmware version:

Press the front panel INFO and DIRECT buttons together for 4 seconds. The firmware version will be displayed on the front panel display (it is the HOST number).

Step 2: Place the current AC-SYSTEM and AC-NETWORK bin files on a USB drive. 

Note that the AC-System file is not model specific, the AC-Network file is model specific.

Be sure there are no other files or previous versions of the firmware on the USB drive.
