There is a really wasy procedure to following - Here goe’s.

Using a computer, get on-line to the web-site stated in your instructions. Once this is done, insert the flash drive into the usb port of your computer, wait for this USB FLASH DRIVE to become active. Now following the instructions provided by the instruction manual or web-page, go to the download section on the web-site. When there, simply click download button, then when the download dialogue box appears, across the top or near it, you will see listed a location on your computer. Change this to read the DRIVE LETTER the computer has assigned to your USB FLASH DRIVE from the drop down list. Once the drive letter has been chosen, simply click save (The filename, and file type should automatically have been entered by the Web-site down load page.). The computer will now download the specified programme, and it will in turn be placed on the USB FLASH DRIVE.

MAKE SURE THAT THE FLASH DRIVE IS OF A SOMEWHAT LARGER SIZE THAN THE FILE TO BE DOWNLOADED. I recommend something like 1gb or bigger.

When the file has downloaded to the FLASH Drive, and the web-site says it is ok , rem ove the FLASH DRIVE, and follow any instructions provided to load the programme for your receiver, into the required slot or hardware.

Hope this helps,

Alex
