SAFETY CHECK-OUT
(US model only) After correcting the original service problem, perform the following safety checks before releasing the set to the customer: Check the antenna terminals, metal trim, "metallized" knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below.
Wow and flutter
4-track 2-channel stereo 40 13,000 Hz (±3 dB), using Sony TYPE I cassette 40 14,000 Hz (±3 dB), using Sony TYPE II cassette ±0.15% W.Peak (IEC) 0.1% W.RMS (NAB) ±0.2% W.Peak (DIN)
LEAKAGE
The AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microampers). Leakage current can be measured by any one of three methods. 1. A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers' instructions to use these instruments. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job. Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The "limit" indication is 0.75 V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2V AC range are suitable.

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens. Laser component in this product is capable of emitting radiation exceeding the limit for Class 1.

SECTION 3 TEST MODE
[Cold Reset] · The cold reset clears all data including preset data stored in the RAM to initial conditions. Execute this mode when returning the set to the customer. Procedure: 1. Press three buttons STOP , DISPLAY , and DISC 1 simultaneously. 2. The fluorescent indicator tube becomes blank instantaneously, and the set is reset. [Tuner Step Change] (Except for European and Middle Eastern models) · A step of AM channels can be changed over between 9 kHz and 10 kHz. Procedure: 1. Press POWER button to turn the set ON. 2. Select the function "TUNER", and press TUNER/BAND button to select the BAND "AM". 3. Press POWER button to turn the set OFF. 4. Press ENTER and POWER buttons simultaneously, and the display of fluorescent indicator tube changes to "AM 9 k STEP" or "AM 10 k STEP", and thus the channel step is changed over. [Function Change Mode] · Select either VIDEO or MD of the external FUNCTION input. Procedure: 1. Turn on the power. 2. Hold down MD(VIDEO) button then press POWER button, and release POWER button first in order not in switch off the set immediately. The another function of the previous function is selected, the input level is also changed and displayed "MD" or "VIDEO". [GC Test Mode] · This mode is used to check the software version, FL tube, LED, keyboard and VACS. Procedure: 1. Press three buttons STOP , DISPLAY , and DISC 2 simultaneously. 2. LEDs and fluorescent indicator tube are all turned on. 3. When you want to enter the software version display mode, press DISC 1 .The model number and destination are displayed. 4. Each time DISC 1 is pressed, the display changes stating from MC version, GC version, CD version, CDDM, CDMA, CDMB, BDA, BDB, ST version, TA version, TM version, TC version, in this order, and returns to the model number and destination display. 5. When DISC 3 is pressed while the version numbers are being displayed except model number and destination, year, month and day of the software creation appear. When DISC 3 is pressed again, the display returns to the software version display. When DISC 1 is pressed while year, month and day of the software creation are being displayed, the year, month and day of creation of the software versions are displayed in the same order of version display. 6. Press DISC 2 button, and the key check mode is activated. 7. In the key check mode, the fluorescent indicator tube displays "KOJOVO". Each time a button is pressed, "KEY" value increases. However, once a button is pressed, _it is no longer taken into account. "VOL" value increases like 1, 2, 3...if rotating VOLUME knob in "+" direction, or it decreases like 0, 9, 8...if rotating in "_"direction. 8. Also when DISC 3 is pressed after lighting of all LEDs and FL tubes, value of VACS appears.

[MC Test Mode] · This mode is used to check operations of the respective sections of Amplifier, Tuner, and Tape. Procedure: · To enter MC Test Mode 1. Press the POWER button t turn on the set. 2. Press the three buttons of STOP , DISPLAY and DISC 3 simultaneously. 3. Cursor segment flash on the FL display tube. The input FUNCTION is changed to GAME.
* Check of Amplifier Initial settings: Input , GAME EQ , FLAT Mode , MUSIC VA CS , OFF Output channel switching: MUSIC key: L , L R , R through MOVIE key: L , SL R , SR through GAME key:L , L, SL, C R , R, SR, SW through TOOL key: L , C R , SW through 1. When the VOLUME control knob is turned clockwise even slightly, the sound volume increases to is maximum and a message "VOLUME MAX" appears for two seconds, then the display returns to the original display. 2. When the VOLUME control knob is tuned counter-clockwise even slightly, the sound volume decreases to its minimum and a message "VOLUME MIN" appears for two seconds, then the display returns to the original display. * Tuner function 1. In the test mode, the default-preset channel is called even when the TUNER is selected and an attempt is made to call the preset channel that has been stored in memory. (It means that the memory is cleared.) 2. The minimum, center and maximum frequency of each band is set then. * Tape recording test 1. To enter the MC Test Mode. 2. Load tapes in both tape decks A and B. 3. Press the REC button to start recording. 4. Pressing the M/+ , m/ buttons during recording returns the tape to the recording start position and stops it at this position. 5. Pressing the "High Speed Dubbing" key while playing back the tape of deck B switches the playback speed between "Normal Speed" and "High Speed". Note: When the playback direction of the tape is set to other than "ONY WAY", the restriction on the number of times playback which can be repeated will be cleared. * AMS Test Mode 1. Set TAPE function 2. Select the desired loop by pressing the PLAY MODE button. Insert a test tape AMS-110A or AMS-120 to Deck A. 3. Press the SPECTRUM (or KARAOKE PON )button to enter the AMS test mode. 4. After a tape is rewound first, the FF AMS is checked, and the mechanism is shut off after detecting the AMS signal the AMS signal twice. 5. Then the REW AMS is checked and the mechanism is shut off after detecting the AMS signal twice.

6. When the check is complete, a message of either OK or NG appears. * To return to normal mode again. 1. When you want to exit this mode, press the POWER button. 2. The cold reset is enforced at the same time. [Aging Mode] This mode can for operation check of tape deck section and CD section. · If an error occurred: The aging operation stops and display then status. · If no error occurs: The aging operation continues repeatedly. Procedure: 1. Press the CD button to select the function "CD". 2. Load the tapes into the decks A and B respectively. 3. Set a disk in "DISK1" tray. 4. Press the PLAY MODE button to set the "ALL DISCS" mode, and press the REPEAT button to "REPEAT" off. 5. Press three buttons of STOP , ENTER , and DISC SKIP/EXCHANGE simultaneously. 6. The aging mode is activated, if the indicator of DOLBY NR is blinking. 7. To exit from the aging mode, operate the cold reset.
[Tape Deck Section] · The sequence during the aging mode is following as below. · If an error occurred, stop display that step. Aging mode sequence (Tape deck section): Rewind the tape A and B "TAPE A AG-1" Shut off FWD play the tape A "TAPE A AG-2" 2 minutes Fast forward the tape A "TAPE A AG-3" Shut off or 20 seconds RVS play the tape A "TAPE A AG-4" 2 minutes Rewind the tape A "TAPE A AG-5" Shut off FWD play the tape B "TAPE B AG-2" 2 minutes Fast forward the tape B "TAPE B AG-3" Shut off or 20 seconds RVS play the tape B "TAPE B AG-4" 2 minutes Rewind the tape B "TAPE B AG-5" Shut off
