Select the function “CD”. 3. Press three buttons x , ENTER , and OPEN/CLOSE simul- taneously. 4. The CD service mode is selected. 5. With the CD in stop status, turn the shuttle knob clockwise to move the pickup to outside track, or turn the shuttle knob counter-clockwise to inside track. 6. To exit from this mode, perform as follows: 1) Move the pickup to the most inside track. 2) Press three buttons in the same manner as step 2. Note: • Always move the pickup 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. [VACS ON/OFF Mode] • This mode is used to switch ON and OFF the VACS (Variable Attenuation Control System). Procedure: Press the ENTER and SPECTRUM buttons simultaneously. The message “VACS OFF” or “VACS ON” appears. [Change-over of MW Tuner Step between 9 kHz and 10 kHz] • A step of MW channels can be changed over between 9 kHz and 10 kHz. Procedure: 1. Press ?/1 button to turn the set ON. 2. Select the function “TUNER”, and press TUNER/BAND button to select the BAND “MW”. 3. Press ?/1 button to turn the set OFF. 4. Press ENTER and ?/1 buttons simultaneously, and the display of fluorescent indicator tube changes to “MW 9 k STEP” or “MW 10 k STEP”, and thus the channel step is changed over. [GC Test Mode] • This mode is used to check the software version, FL tube, LED, keyboard and VACS. Procedure: 1. Press three buttons x , ENTER , 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 starting from MC version, GC version, VC version, CD version, CM version, ST version, TC version, TA version, TM version and BR 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 “KEY0 VOL0”. 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. 9. To exit from this mode, press three buttons in the same manner as step 1, or disconnect the power cord. www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com 13 [MC Test Mode] • This mode is used to check operations of the respective sections of Amplifier, Tuner, CD and Tape. Procedure: 1. Press the ?/1 button to turn on the set. 2. Press the three buttons of x , ENTER and DISC 3 simultaneously. 3. A message “TEST MODE” appears on the FL display tube. 4 When f (CURSOR UP) button is pressed, GEQ increases to its maximum and a message “GEQ ALL MA” appears. 5. When F (CURSOR DOWN) button is pressed, GEQ decreases to its minimum and a message “GEQ ALL M1” appears. 6. When g (CURSOR LEFT) or G (CURSOR RIGHT) button is pressed, GEQ is set to flat and a message “GEQ FLAT” appears. 7. When the VOLUME control knob is turned clockwise even slightly, the sound volume increases to its maximum and a message “VOLUME MAX” appears for two seconds, then the display returns to the original display. 8. When the VOLUME control knob is turned 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. 9. 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, by operating the Shuttle knob. (It means that the memory is cleared.) 10. When CD is selected and the EDIT button is pressed, the disc that is being chucked at this moment becomes the default setting. It means that the default disc only is accessed when any other discs are selected even though the display indication changes accordingly. At the same time, the DISC SKIP EX- CHANGE and OPEN/CLOSE cannot be accepted. (It means that the tray motor and the turntable motor are disabled of their operation.) 11. When a tape is inserted in Deck B and recording is started, the input source function selects VIDEO automatically. 12. When x button is pressed to stop recording, the Tape (Deck) B is selected and tape is rewound using the Shuttle knob, tape is rewound, tape is stops at around the record-starting position and playback of the recorded portion of the tape is started. If PAUSE is inserted even once during recording, tape is rewound to the position around the PAUSE position and is played back. 13. When the CD SYNC HI-DUB Button is press during playback of Deck B, either normal speed or high speed can be selected by this button. 14. Select the desired loop by pressing the PLAY MODE button. Insert a test tape AMS-110A or AMS-RO to Deck A. 15. Press the SPECTRUM button to enter the AMS test mode. 16. After a tape is rewound first, the FF AMS is checked, and the mechanism is shut off after detecting the AMS signal twice. 17. Then the REW AMS is checked and the mechanism is shut off after detecting the AMS signal twice. 18. When the check is complete, a message of either OK or NG appears. 19. When you want to exit this mode, press the ?/1 button twice. The cold reset is enforced at the same time. www. xiaoyu163. com QQ 376315150 9 9 2 8 9 4 2 9 8 TEL 13942296513 9 9 2 8 9 4 2 9 8 0 5 1 5 1 3 6 7 3 Q Q TEL 13942296513 QQ 376315150 892498299 TEL 13942296513 QQ 376315150 892498299 http://www.xiaoyu163.com 14 [Aging Mode] This mode can be used for operation check of CD section and tape deck section. • If an error occurred: The aging operation stops and display status. • If no error occurs: The aging operation continues repeatedly. 1.
