					Firmware for 5000-AVD
				     Audio/Video Broadcast Delay


This release contains System Firmware version 2.2.0 and Boot file version 2.1a

See Manual for full information on installing this firmware update.




			  Installing on Cards with version 1.x.x Firmware:


For cards which have existing System Firmware versions lower than 2.0.0, this update must be
installed with a MMC or SD memory card.

Copy this entire folder to a MMC or SD memorey card's root directory.
Note: There must not be any other folder on the memory card's root directory with a name that ends in ".cme".

Insert the memory card into the socket on the front edge of the 5000-AVD card.
Push and hold in the "FLASH" button (located above the memory card socket) until the LED begins flashing.

The LED should rapidly flash red for approximately 20 seconds while the firmware is copied to the 5000-AVD.
The LED should then rapidly flash green for approximately 10 seconds while the installation is verified.
The LED should alternate red and green when the installation is complete.

Remove memory card.

The LED should again rapidly flash red for approximately 10 seconds while a new boot file is created.
The LED should again rapidly flash green for approximately 5 seconds while the boot file is verified.

The 5000-AVD should then automatically reboot with the new firmware.


	WARNING! DO NOT REMOVE MEMORY CARD OR CYCLE POWER WHILE THE LED IS RAPIDLY FLASHING RED.
		 THIS MAY CORRUPT THE FIRMWARE FILES PREVENTING THE CARD FROM BOOTING.


After installation, verify that the status menu in Dashboard indicates:
Software version - 2.2.0
Boot version - 2.1a
