Although as I remember the manual is very very inadequate, I do have one. It might take a day or three to dig it out... and then a photocopy could be sent to you. If you do not find any other sources (like a nicely formatted online file you can print) let me know, and I can photocopy the one I have for you.
PLEASE ! to reduce bandwidth on this system, Contact me directly via E-mail My address is below. Please REMOVE the first two letters "NS" to obtain a useable address. (my poor attempt to foul address CRAWLERS!)NSCAMIJON@TECHIE.COM
I can send it to you via USPS.
If I do not hear from you I will assume you found another source.
P.S. LOVE(ed) my FT-470 it was (is) a GREAT Radio.
The mods (non-invasive keypad entry type) work very well. This forum might be a nice place for you to get THAT type of info.
Best of Luck
