i asked this question a few months ago.
seems like there is no online version of their manual.
u can purchase the manual from KO directly.this is what i got from them:
Thank you very much for your inquiry.
Yes, we have it here in stock.
The part#19807, its $15.00ea., and shipping fee is $3.85 by priority mail in
We are wondering why you have 40Mhz Japanese version, but once we received
your request with payment(pay to the order: KO PROPO USA, INC.), we are
pleased ship it out right away.

I know u'd be a little(not) unhappy about having to buy a manual..heehee.
anyway to change user levels...
switch it off....hold the 2 top buttons and switch it on again.
to exit this function press the top left button.
otherwise just scroll thru with the middle 2 buttons and adjust what u want.i like level 4 bcos i dont understand my japanese manual and i definitely dont understand more than 70% of the functions...so whenever i lose i'd just say:damn this radio...wait till i figure it out.lol
