Procedure 2: 1.Press the?/1*1 button to turn the power ON. 2.While pressing the both PLAY MODE*2 andx

23、*2 buttons, press theZ(DISC 1)*2 button. 3.LEDs and fluorescent indicator tube are all turned on of all units. Version Display Mode Procedure: 1.Enter the GC test mode. 2.Each time the TUNER MEMORY or DISC 1*2 button is pressed, microcomputer or mechanism deck version is displayed of each unit. 3.Pr

24、ess the TUNING + or DISC 3*2 button to detail is displayed the version. Key Check Mode Procedure: 1.Enter the GC test mode. 2.Press the TUNING - or DISC 2*2 button to set the key check mode. 3.In the key check the mode, the fluorescent indicator tube displays “K 0 J 0 V 0” . Each time a button is pr

25、essed, “K” value increases. However, once a button is pressed, it is no longer taken into account. VACS Level Display Mode Procedure: 1.Enter the GC test mode. 2.Press the TUNING + or DISC 3*2 button to display VACS level on the fluorescent indicator tube. Segment Check Mode Procedure: 1.Enter the G

26、C test mode. 2.Press the ENTER orx *2 button to set the segment check mode. 3.In the segment check the mode. Each ENTER orx*2 button is pressed, the fluorescent indicator tube displays is switching variously. Releasing the GC Test Mode To release from this mode, press three buttons in the same manne

27、r as entering this mode or disconnect the power cord. Note: Use following buttons in the test mode. no mark: Button of tuner unit (ST-S9) *1: Button of amplifier unit (TA-S9D) *2: Button of DVD/video CD/CD unit (DVP-S9) MC Cold Reset The cold reset clears all data including preset data stored in the

Procedure 2: 1.Press the?/1*1 button to turn

29、 the power ON. 2.While pressing the both PLAY MODE*2 andx *2 buttons, press theM *2 button. 3.The set is reset, and becomes standby state. 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 ou

30、t. Procedure: 1.Press the?/1*1 button to turn the power ON. 2.While pressing the both STEREO/MONO and CINEMA STUDIO C*1 buttons, press the TIMER SELECTbutton. 3.The set is reset, and becomes standby state. Change-over the AM Tuning Interval (EXCEPT AEP, UK and Sauidi Arabia models) The AM tuning int

31、erval can be changed over 9 kHz or 10 kHz. Procedure: 1.Press the?/1*1 button to turn the power ON. 2.Turn the FUNCTION *1 knob to select “TUNER”, and press the TUNER/BAND button to select the BAND “AM”. 3.Press the?/1*1 button to turn the power OFF. 4.While pressing the ENTER button, press the?/1*1

32、 button, and the display on the fluorescent indicator tube changes to “AM 9 K STEP” or “AM 10 K STEP”, and thus the tuning interval is changed over. Change-over of VACS ON/OFF 1.Press the?/1*1 button to turn the power ON. 2.While pressing the both STEREO/MONO and CINEMA STUDIO C*1 buttons, press the

33、 CINEMA STUDIO B button, and VACS ON/OFF is change over.
