There's a PalmInfocenter forum post with directions for getting the T5 manuals from the FCC site.
I'm having trouble with my internet connection, but try the FCC site
https://gullfoss2.fcc.gov/prod/oet/c...ericSearch.cfm and Search for Grantee Code: 'O3W' and pick 10/4/2004 entries.
You should end up at FCC ID 'O3W820' if you click on details for that entry. Then you can do save target as... to get the pdf files with cover letters, pics, manuals, etc.
