The manual was exactly what I wanted and I found it nowhere else. Thanks!

Having purchased a 1994 Kenwood music system from a Charity shop in 2013 (it was a high end product in its day), I found myself not quite knowing where to plug in what, and how to do this, that and the next thing. I needed a Manual, and after failure with another online 'Manual provider' I found Owner Manuals dot com. Well, I wasn't sure, but it was only $5, and if things didn't work out, I wouldn't have lost much...
But things DID work out. After paying my childrens inheritance money, $4.99, I was sent a Manual for my Kenwood System very quickly. Alas, it was in German, and being Scottish, I could not read it or get my system in order from it...a rapid email to them brought the English Manual in short order, and my retro-system was and IS up and running in it's regulation settings.
I am very grateful to http://www.owner-manuals.com for their quick service and for even having such an obsolete Manual in the first place! If you need a Manual for ANYTHING, try here first. I wouldn't be surprised if I bought a 1928 Marconi radio, and got the user Manual for THAT here too!
Top marks.

I was so happy that the owner's manual was available. It is well written and helped me to use the radio/CD player/recorder without problems. Thanks for making it available.

Excellant!!! Very quick and easy....Best $4.99 I have spent in a very long time..
I highly recommend this.

Thanks so much for the Owner's manual for my Sony PS - FL1. I had purchased the turntable off of eBay. It came in and looked great. Packed well and appeared to be great. I balanced and aligned the tone are and hooked it up. When trying to play a record the tone are would move to the right place and just before it would drop to play it moved back off the edge of the record before touching down. I searched the net for an answer to this issue. No luck. Then I purchased the owners manual and sure enough there was a place to adjust where the stylus touched down. That adjustment solved the problem and saved me a $35 feet to have the player checked out. The manual is well written and easy to understand. It is a must have for anyone with this front loading Sony turntable.

Risetime Measurements Risetime measurements employ basically the same techniques as time-duration measurements. The main difference is the points between which the measurement is made. The following procedure gives the basic method of measuring risetime between the 10% and 90% points of the waveform. Falltime can be measured in the same manner on the trailing edge of the waveform. 1. Connect the signal to be displayed to the input of the Amplifier plug-in unit. 2. Set the Vertical and Horizontal Mode switches on the oscilloscope to display the plug-in units used. 3. Set the Volts/Division switch and the Variable Volts/ Division control of the Amplifier plug-in unit to produce a signal an exact number of divisions in amplitude. 4. Center the display about the center horizontal graticule line with the Amplifier plug-in unit Position control. 5. Set the MAIN TRIGGERING controls to obtain a stable display. 6. Set the TIME/DIV OR DLY TIME switch to the fastest sweep rate that displays less than 8 divisions between the 10% and 90% points on the waveform. 7. Determine the 10% and 90% points on the rising portion of the waveform. The figures given in Table 2-1 are for the points 10% up from the start of the rising portion and 10% down from the top of the rising portion (90% point).
Example: Assume that the horizontal distance between the 10% and 90% points is 4 divisions (see figure 2-8) and the TIME/DIV OR DLY TIME switch is set to 20 ns. Applying the time duration formula to risetime: Time Duration = (Risetime) horizontal distance (divisions) TIME/DIV OR x DLY TIME setting
Substitute the given values: Risetime = 4 x 20 nanoseconds = 80 nanoseconds

Vertical display (divisions) 4 5 6 7 8 10% and 90% points (divisions) 0.4 and 3.6 0.5 and 4.5 0.6 and 5.4 0.7 and 6.3 0.8 and 7.2 Divisions vertically between 10% and 90% points 3.2 4.0 4.8 5.6 6.4

Delayed Sweep Measurements The delayed sweep mode can be used to make accurate time measurements. The following measurement determines the time difference between two pulses displayed on the same trace. This application may also be used to measure time difference from two different sources (dual-trace) or to measure time duration of a single pulse. 1. Connect the signal to be displayed to the Amplifier plug-in unit. 2. Set the Vertical and Horizontal Mode switches on the oscilloscope to display the plug-in units used. 3. Set the Volts/Division switch of the Amplifier plug-in unit to produce a display about 4 divisions in amplitude. 4. Adjust the MAIN TRIGGERING controls for a stable display.
8. Measure the horizontal distance between the 10% and 90% points. Be sure the VARIABLE control is set to CAL. 9. Multiply the distance measured in step 8 by the setting of the TIME/DIV OR [)LY TIME switch.
