If you've lost the instruction book for just about anything, don't worry - it's probably available as a PDF document on the Web. Put the manufacturer's name in the address bar and hit CTRL-ENTER, and most likely you'll get right where you want to be.
I found instructions for our office phone system, and an owner's manual for my Honda, along with instructions for stereo equipment I bought at garage sales.
And the installation disk that comes with printers? - It's all on the Web.
