Therefore, when checking the laser diode emission,observe from more than 30 cm away from the objective lens.LASER DIODE AND FOCUS SEARCH OPERATIONCHECKCarry out the “S curve check” in “CD section adjustment” andcheck that the S curve waveform is output two times.CD-TEXT TEST DISCThis unit is able to display the text data (character information)written in the CD on its fluorescent indicator tube.The CD-TEXT TEST DISC (TGCS-313: J-2501-126-A) is usedfor checking the display.To check, perform the following procedure.Procedure:1. Turn ON the power and set the test disc.2. Press the ” button and play back the disc.3. The following will be displayed on the fluorescent indicator tube.Display : 1kHz/0 dB/ L&R4. Rotate the AMS knob to switch the track. The textdata of each track will be displayed.Restrictions in CD-TEXT Contents and DisplayThe micro processors RAM has limit of capacity in this unit, Thedisplay may not show all the track titles in a disc when you play theCD TEXT TEST DISC, but it is not unusual. In that case, “NOTDISPLAY” appears in the display. 4 SECTION 2GENERALLOCATION OF PARTS AND CONTROLSFront Panel! AMS* knob! PHONES jack! p (stop) button! P (pause) button! (play) button!

ADJ MODEThe following operations are performed in the ADJ mode, whichis set by connecting the TP1 (ADJ) terminal to the Ground andturning on the power. During playback, there is no problem even if the GFS is continu-ously LOW. High speed search is prohibited during access. During playback, the gain of focus servo and spindle servo doesnot decrease. Servo related manual operations and measurement can beperformed.(For details of operations, refer to Table of Button Operrations inADJ Mode.)Table of Button Operations in ADJ ModeThe jitter value display mode can be set after the all-musicremaining number mode using the TIME button.The functions of the number buttons are shown in the followingtable.Function of Number Buttons(With the Attached Remote Commander)1234567810Focus bias 8-step upMiddle of focus bias up/down turning pointTracking servo, sled servo offAuto gain initializationFocus servo offFocus bias 8-step downImmediate readjustment of focus biasTracking servo, sled servo onAuto focus bias start pointFunctionButton4-3.
