clarion PU2294 - turn off code entering / source of manuals?

Hi there
I see there are a lot of messages here about entering the code for
Clarion radios. This isn't quite one of those ;-) ...

I recently bought a Clarion PU-2294 ((D), I think) as a replacement
Radio/CD player for my 306. I have got the code entered fine. However
the radio seems to want me to enter the code each time I turn the
ignition on.

My old Blaupunkt had a way of setting it so you had to enter the code
each time, or not. Can anyone tell me if the Clarion has an
equivalent, and how I access it? I've come across a couple of features
by holding down buttons etc., but haven't yet found the right
combination to do what I want.

More generally, is there a source of (possibly downloadable?) manuals
for the older Clarion radios? Their web site doesn't seem too helpful
in this regard.

I may post a followup on fitting the thing properly into my '306 - do
I need a new metal DIN shell, does anyone know? - but I'll leave that
one for now ...

Thanks very much for any replies.

Cheers

Its the wiring problem....no constant feed thus the radio has no memory.
Take the headunit out and you should see a red and yellow wire, connect up
yellow. Yellow for constant and what you should have now is red which is
ignition thus switched power.
