I am the happy new owner of a 1988 Porsche 911 Targa. The car came
with an Alpine 7803S radio/CD changer but with no owners manual for
the radio. I've spoken to tech support at Alpine but they haven't
been able to help me and all my searches for an owners manual have
been unsuccessful.

I have figured out almost everything I need to know about the radio
with a few exceptions:

How do you set the preset buttons to remember a radio station?
What does the DAP button do?
There is a button on the upper left of the faceplate (next to the clk
and scn button labelled MO/DX.. What does that do?
