 SV-260A TECHNICS Owner's Manual by Seb Petrescu;
Useful manual, good scan, worth the pay if you find the unit difficult to operate.
 PM5191 PHILIPS Owner's Manual by Benedikt Jochims;
Exactly as described, the full user-manual (145 pages). Perfect.

Text excerpt from page 13 (click to view)
3-2. Display of History of DSP Operations • When “DSP error detected!” is displayed on the fluorescent display tube, the history of DSP errors will be displayed eight seconds later. (See Fig. 1.) • This history will be displayed if a DSP error has occurred in the past. It helps the detection of malfunction parts by enabling past problems of the unit to be checked. • This history shows the “Cause of error” and “How many times occurred” for the two DSPs. (See Fig. 1.)

4. Operation Check Mode • During the operation check mode, functions can be set by pressing the corresponding button. (See Table-3.) • Each time a button is pressed, the corresponding function will be displayed for about 8 seconds. • Buttons other than those displayed in Table-3 operate usually. NOTE: Do not press the SET UP button during the operation check mode. As this button is provided with a special function for debugging, pressing it may impede the normal output of signals in the sub-woofer mode. Table-3:

Number of times the error has occurred

DIG-2 Outputs the Lch DIGITAL-2 input signal to (L-SL, R-SR) the REAR Lch and the Rch to the REAR Rch. Outputs the Lch DIGITAL-3 input signal to DIG-3 (L-C, R-SW) the CENTER and the Rch only to the WOOFER.

How to read the display • The left side shows the errors of the first DSP (DSP56009:MAIN board IC424) and the right side shows the errors of the second DSP (SSP424023:MAIN board IC423). • The “How many times occurred” indicates the number of times that the error has occurred. If an error has occurred more than 256 times, it will be displayed as 256. • The 1 2 3 4 part shows 0 or 1 according to the cause of the error. If an error has occurred, 1 will be displayed. If no error has occurred, 0 will be displayed. (See Table-2.) Table-2:
Cause of error 1 Failed in initial booting 2 DSP does not operate 3 Communication port malfunction Possible cause Mostly due to faulty connection (soldering) between DSP and microprocessor Faulty DSP clock (X401 and onwards), faulty DSP part, etc. Overrunning of DSP due to heat, microprocessor bugging, or IC301 (MAIN board PLL) is faulty



DIG-4 (L, R-ALL)

Outputs the Lch DIGITAL-4 input signal to the FRONT Lch, REAR Lch, CENTER, and the Rch to the FRONT Rch, REAR Rch, and CENTER.

By pressing the MENU knob and displaying “<<< LEVEL ADJUST >>>”, and rotating the +/– knob to the right, the input signal selected at that time can be output to any Lch or Rch channel. (See Table-4.)

Fluorescent Display Tube Display Exchange (L-SL, R=SR) Output Destination of Input Signal Outputs the FRONT Lch/Rch signal only to the REAR Lch/Rch. Outputs the FRONT Lch signal only to the REAR Lch, and FRONT Rch signal to the REAR Rch. Outputs the FRONT Lch/Rch signal to the FRONT Lch/Rch, the REAR Lch/Rch signal to the REAR Lch/Rch, the CENTER signal to CENTER, and the WOOFER signal to WOOFER as usual. Outputs the FRONT Lch signal to the FRONT Lch, REAR Lch, and CENTER, and the FRONT Rch signal to the FRONT Rch, the REAR Rch, WOOFER.

4 No reply from DSP Faulty DSP part, or faulty microprocessor part, etc.

NOTE: This history is memorized in the EEPROM until the unit is initialized. (Refer to “5. Initialization” on page 14.)
