I have the SEA 223 SSB but just happen to have a copy of the SEA 222 manual
as well..

If I'm correct and your are in fact looking for this model, let me know and
I will send it to you..

BTW. Their manuals are excellent, easy to understand and includes a lot of
theory of operation. The equipment is very easy to repair in the field.
