Sony CD ROM drive model CRX140E

Hi I need help with my Sony 5cd changer model #RCD-W500C
Compact Disc Recorder AC 120 V 60Hz 25W serial #9021823 When I purchased this abour 7-9 years ago and ther weren't any manual instructions on how to use it. My husband experimenting with it had figured out the basics, time has past and since then we haven't used it and now I would like to use it but I don't know how. Can you help me with this?

Here is the manual of the cd burner:

Please look on page 11 on this manual there it is described.
