Actually, I was looking for this information for 3 years!...now thanks to you, the manual is on my hands and of great help, cause I understand now where I was doing wrong connections and wires...excellent, I'll be back to you if in need, thank you.
This manual covers the main equipment features only. While it also includes the procedure for saving and loading from the now long obsolete memory cards it does not mention the how to operate with the optional floppy drive interface so I am still at a loss about how to use this! Note that there is a separate manual covering the MIDI interface and programming via the keyboard, not included in this download. You will also need to get hold of this if you want to use the MIDI interface properly. Basically there is little difference between this manual and the free to download manual for the similar PR60 model.
Good list of manuals. I found a very rare one and easily get. Should be promptly to download, as we must to wait hours even after confirmed payment.

Notes � Match the timer of the connected source with the unit�s setting. (In the case of the mic input, ensure that the microphone has been connected to the unit.) � Recording starts at the programmed start time, and the power will be switched to STANDBY at the programmed end time. When operation is completed once in the ONCE TIMER mode, the timer programming is cleared. � If digital signals are not supplied when timer recording has been started with digital input signals, �UNLOCK� is displayed and no signals will be recorded. � When using the timer to record a digital satellite broadcast program, for instance, check that the broadcast station with the desired program can be tuned in correctly before programming the timer start and end times.
