Toshiba RT-S77 User/Service Manual Needed

Hello everybody,
some time ago I got a stereo radio cassette recorder Toshiba RT-S77. I cannot find any docs for this unit. It seems to me that it was designed for and distributed in Japan only. Even labels for all knobs/buttons are in Japanese (and 100VAC power also is in place). Can somebody at least to comment or to explain the purpose of each control item? Any help would be appreciated!
Even better would be to get a User or Service manual...

Cheers from Russia!
