It has two rows of buttons with three buttons in each row. A third row
has five buttons for the preset stations. I'm pretty sure the rightmost
button in the first row is for the preset. It's the only cheap radio
I've seen that has presets, probably 12 years old.

Then choose the letter "D" for Dream Machine.
You will see several similar models.
I'm sure they operate almost the same.
I have a model but it is number 430 so I won't give you the
instructions, as you can read several variations on the site I gave
you.
Or even better yet, here

You can read/see the actual manual
Hope that helps
The "trick" was to press the preset button (labeled enter), then press
the preset button wanted for the dial setting displayed. I kept hold the
Enter button and simultaneously holding down the preset button. Yikes!
