The following sections tell you how to use the Soft-
ware Upgrade Utility screen.

If you enter the Software Upgrade Utility acciden-
tally, enter the command G to quit. If you give no 
keyboard input for 30 seconds, the utility will time 
out.

Enter command R and then command G if you do 
not want to download a new software image.

will be downloading the new software image
