Hey,

I was in the same boat as everyone, and spent the last
two days looking for instructions on how to program my
JER-321 remote, with no success. I finally decided, as
we need a new remote for our downstairs tv anyways, to
buy another JER-321 remote. SO here are the instructions
for the manual code search:

1.Manually turn on the component you want the remote to
control.
2.Press and hold the component key (TV, VCR, Etc..) you
wish to program. The illuminated ON-OFF key turns and
remains on.
3.While holding the component key down, press and hold
the ON-OFF key. The illuminated ON-OFF key turns off.
4.After holding down both keys for three seconds, the
illuminated ON-OFF key turns back on.
5.Release both keys. The illuminated ON-OFF key remains
on.
6.Press and release the ON-OFF key repeatedly until your
component turns off. Wait four seconds between each keypress.
Each time you press the ON-OFF key, the illuminated ON-OFF
key blinks and the next code in the list is sent. This
process continues until all of the codes in the Code lists
have been searched. If your component turns off, you have
found the correct code.
7.Once you have found the correct code, you must save
the new code by pressing and releasing the STOP key. The
illuminated ON-OFF key turns off. You must press the STOP
key to save the code or the correct code will not be stored.

I know, I am the best :)

This should work for everyone. Hope this helps a lot of
people out there.
