The owner's manual/operating instructions that I purchased was the original factory document and it was in at least three and maybe more languages. I no longer have it because I sold the tape recorder and included the owner's manual/operating instructions and a service/repair manual that I bought on ebay for the new owner.
Turns out this was not the manual i was looking for. The concertmate 670 keyboard i have is a "Realistic" model made for Radio Shack and none of the diagrams on the owners manual i received matches up. HOWEVER, I must say the service Owners Manual provides was fast and efficient by being available online. The manual was in good readable condition and easily downloaded.
Great price, Quick delivery, the document was very usefull A+++++++++++++++

XC-E series
RESTART RESET (R.R)
The information on one screen can be extracted at any time by inputting a restart/reset signal (HD/VD) from the outside. To enter this mode, set DIP switches 6, 7, and 8 on the rear panel of a camera as shown in the table below. The setting is especially effective for the following operation.
Switch 1 2 3 4 5 6 7 8 9 0 Restart Reset (R.R) 0 0 0 0 0 1 1 1 0 0

Long exposure
A high-sensitivity image is obtained by extending the exposure time of the CCD when satisfactory sensitivity cannot be obtained under other operating conditions or when observing the trail of a moving object. The exposure time is determined by the VD interval (T) period between external VD pulses as follows.
� Timing and conditions
Example 1 of Long exposure
EXT HD
Continuous signal: 15.734 kHz (XC-ES50/ES30, XC-EI50/XC-EI30)Allowable frequency value ±1%, 15.625 kHz (XC-ES50CE/ES30CE, XC-EI50CE/XC-EI30CE) Allowable frequency value ±1%
EXT VD
VD interval(T): 262.5H or more (XC-ES50/ES30, XC-EI50/XC-EI30) and less than 1 second (Recommended), 312.5H or more (XC-ES50CE/ES30CE, XC-EI50CE/XC-EI30CE) and less than 1 second (Recommended) Four or more VD pulses are required. T T T
Exposure time for Odd field Exposure time for Even field
Video output
Odd image Invalid image Even image Valid frame image
Odd and even fields are determined by the phase of the EXT HD/VD signal input from the outside.
