Gal needs to know-- pin codes, fuse, manual??

[minmn]

I've got a 1994 corolla, automatic ( CAC, clock, tape+radio). I just pulled out the dead battery. Afterwards I started reading on the internet and found a video about battery replacement. It said something about pin codes for electronic stuff being erased after the battery is removed. I haven't installed the new one, as I have to clean the terminals.
a. Do I have pin codes that got erased by removing the battery?
b. IF SO, what are they; where are they; & how do I reset them?

Also:
c. I don't see the battery fuse labeled on the 2 fuse boxes. I wanted to check if it is okay, but can't find it.
d. Where do I find a free online owners manual? So far my searches yield zip.
Thanks for your help.

maybe they mean radio code, i don't think your radio has one.

the 'battery fuse' is a large 100something amp fuse in the underhood fuseblock held in by 2 bolts, its a straight leg pal type fuse.

The radio code they refer to is just as bitter said, a security code with some radios offered in higher end vehicles so if the stereo is stolen, it can't be reused without it.
You will just need to put in your new battery, need to reset the time on the clock, and program your "preset" radio stations into the radio. That is done by just holding the preset button down once your on the station of choice until it beeps, then its saved.
I would simply replace the battery and then if you still have issues, verify if the fuses are good or not, or come back and we can help you further.

Just make sure not to mix up the polarity when hooking up the battery (would be hard to) but if you do, you will blow the main battery fuse.
