SECTION 4 SERVICE MODE

MC 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 p , ENTER/NEXT , and 1/u simultaneously. 2. COLD RESET is displayed on the fluorescent display tube and reset is executed. CD Delivery Mode This mode moves the pick-up to the position durable to vibration. Use this mode when returning the set to the customer after repair. Procedure: 1. Press 1/u button to turn the set ON. 2. Press LOOP button and 1/u button simultaneously. 3. A message LOCK is displayed on the fluorescent indicator tube, and the CD delivery mode is set. MC Hot Reset This mode resets the set with the preset data kept stored in the memory. The hot reset mode functions same as if the power cord is plugged in and out. Procedure: 1. Press three buttons p , ENTER/NEXT , and DISC 1 simultaneously. 2. The fluorescent indicator tube becomes blank instantaneously, and the set is reset. Sled Servo Mode This mode can run the CD sled motor freely. Use this mode, for instance, when cleaning the pick-up. Procedure: 1. Press 1/u button to turn the set ON. 2. Press three buttons p , ENTER/NEXT , and simultaneously. 3. The Sled Servo mode is selected, if CD is blanking on the fluorescent indicator tube. 4. With the CD in stop status, When the 0 AMS ) knob is rotated in the clockwise direction, the pick-up moves outside. When rotated counterclockwise, it moves inside. 5. To exit from this mode, perform as follows: 1) Move the pick-up to the most inside track. 2) Execute MC cold reset. (Press the three buttons p , ENTER/NEXT , and 1/u button simultaneously.) Note: Always move the pick-up to most inside track when exiting from this mode. Otherwise, a disc will not be unloaded. Do not run the sled motor excessively, otherwise the gear can be chipped. Change-over of AM Tuner Step between 9kHz and 10kHz A step of AM channels can be changed over between 9kHz and 10kHz. Procedure: 1. Press 1/u button to turn the set ON. 2. Select the function TUNER, and press TUNER/BAND button to select the BAND AM. 3. Press 1/u button to turn the set OFF. 4. Press ENTER/NEXT and 1/u buttons simultaneously, and the display of fluorescent indicator tube changes to AM 9k STEP or AM 10k STEP, and thus the channel step is changed over. LED and Fluorescent Indicator Tube All Lit, Key Check Mode Procedure: 1. Press three buttons p , ENTER/NEXT , and DISC 2 simultaneously. 2. LEDs and fluorescent indicator tube are all turned on. Press DISC 2 button, and the key check mode is activated. 3. In the key check mode, the fluorescent indicator tube displays K 0 V0 J0. Each time a button is pressed, Kvalue increases. However, once a button is pressed, it is no longer taken into account. J Value increases like 1, 2, 3. if rotating 0 AMS ) knob in + direction, or it decreases like 0, 9, 8. if rotating in - direction. V Value increases like 1, 2, 3. if rotating VOLUME knob in + direction, or it decreases like 0, 9, 8. if rotating in - direction. 4. To exit from this mode, press three buttons in the same manner as step 1, or disconnect the power cord.

AMS Test Mode This mode is used for checking the AMS operations of the tape deck. JIG 7-819-039-12 Alignment tape, AMS-110A Procedure: 1. Press the 1/u button to turn the unit ON. 2. Set the tape (AMS-110A). 3. Press the three buttons p , ENTER/NEXT , and DISC 3 button simultaneously. 4. TEST MODE is displayed on the fluorescent display tube. 5. Press the FUNCTION button and switch the function to the deck with the tape (AMS-110A). 6. Press the CD SYNC button. AMS CHECK is displayed on the fluorescent display tube and the tape is rewound. 7. AMS starts in the normal direction. If the AMS count is 2 at shut down, proceed to step 8. NG is displayed at other times, and the deck stops. 8. AMS starts in the opposite direction. If the AMS count is 2 at shut down again, OK is displayed. NG is displayed at other times. Note: The p button of CD section will become effective and the aging of CD section will stop sometime, if the buttons described in step 3 are not pressed simultaneously. In that case, press ^ button and operate the CD section. Aging Mode During the aging mode, both the CD player and tape deck are executed together. If an error occurs: Aging stops, and the error state is displayed on the fluorescent display tube. If no error occurs: Aging is repeated. Procedure: 1. Press the 1/u button to turn the unit ON. 2. Load 10 minute tapes with unbent rec-proof tabs in decks A and B. 3. Set CD on the DISC 1 table. 4. Set the CD mode REPEAT to OFF and PLAY MODE to ALL DISCS. (Press the PLAY MODE/DOLBY NR and REPEAT/STEREO/MONO buttons to set these modes.) 5. Press the FUNCTION button to switch the function to CD. 6. Press the three buttons p , ENTER/NEXT , and DISC SKIP/EX-CHANGE button simultaneously. 7. Aging starts. 8. To end aging, press the 1/u button to turn the unit OFF. Aging Sequence: Aging is performed in the following sequence. Tape Deck 1. The tape in deck A is rewound. TAPE A AG-1 is displayed. 2. The FWD side of deck A is played for two minutes. TAPE A AG-2 is displayed. 3. The tape in deck A is fast forwarded. TAPE A AG-3 is displayed. Fast forward is carried out for 20 seconds or to the tape end. 4. The RVS side of deck A is played for two minutes. TAPE A AG-4 is displayed. 5. The tape in deck A is rewound. TAPE A AG-5 is displayed. 6. The FWD side of deck B is played for two minutes. TAPE B AG-2 is displayed. 7. The tape in deck B is fast forwarded. TAPE B AG-3 is displayed. Fast forward is carried out for 20 seconds or to the tape end. 8. The RVS side of deck B is played for two minutes. TAPE B AG-4 is displayed. 9. The tape in deck A is rewound. TAPE A AG-5 is displayed. 10. Repeated from step 2. CD 1. The tray rotates. 2. DISC 1 is chucked. 3. The TOC is read. 4. The first track is played for 2 seconds. 5. The last track is played for 2 seconds. 6. Repeated from step 1.

Note: The components identified by mark ! or dotted line with mark ! are critical for safety. Replace only with part number specified. When indicating parts by reference number, please include the board name. Due to standardization, replacements in the parts list may be different from the parts specified in the diagrams or the components used on the set. -XX, -X mean standardized parts, so they may have some difference from the original one. Items marked * are not stocked since they are seldom required for routine service. Some delay should be anticipated when ordering these items.
