angle of the pickup unit cannot be adjusted after the pickup unit is changed. The pickup unit in the CD mechanism module is adjusted on the production line to match the CD mechanism module and is thus the best adjusted pickup unit for the CD mechanism module. Changing the pickup unit is thus best considered as a last resort. However, if the pickup unit must be changed, the grating should be checked using the procedure below. • Purpose : To check that the grating is within an acceptable range. • Symptoms of Mal-adjustment : If the grating is off by a large amount symptoms such as being unable to close tracking, being unable to perform track search operations, or track searching taking a long time, may appear. • Method : • Measuring Equipment • Oscilloscope, Two L.P.F. • Measuring Points • E, F, REFO • Disc • ABEX TCD-784 • Mode • TEST MODE • Checking Procedure 1. Enter Test mode, then select Multi-CD player and switch the 5V regulator on. 2. Using the TRK+ and TRK- buttons, move the pickup unit to the innermost track. 3. Press key 9 to close focus, the display should read "91". Press key 9 2 times. Enter Rough Servo mode. Press key 8 to implement the tracking balance adjustment the display should now read "81". 4. As shown in the diagram above, monitor the LPF outputs using the oscilloscope and check that the phase differ- ence is within 75° . Refer to the photographs supplied to determine the phase angle. 5. If the phase difference is determined to be greater than 75° try changing the pickup unit to see if there is any improvement. If, after trying this a number of times, the grating angle does not become less than 75° then the mechanism should be judged to be at fault. • Note Because of eccentricity in the disc and a slight misalignment of the clamping center the grating waveform may be seen to "wobble" ( the phase difference changes as the disc rotates). The angle specified above indicates the aver- age angle. • Hint Change the disc changes the clamp position and may decrease the "wobble". REFO E F E F L.P.F. L.P.F.

To absorb dislocation of the stage height caused by differences in the mechanism and the CD core unit, adjustment must be made for each CD-mechanism module using a variable resistor. Normally, readjustment is not needed, as this has been adjusted at the factory. However, adjustment of elevation is required according to the procedure explained below if an elevation error has occurred or if the CD core unit has been removed. • Purpose : To adjust and confirm whether or not elevation operates correctly. • Adjustment Method : • Measuring Equlpment: Oscilloscope, One L.P.F. • Measuring Points : EREF, EPVO • Setting : Without a magazine in Test mode With the mechanism placed upside-down (Place the CD mechanism module so that the CD core unit is above.) • Confirmation Procedure 1. Enter Test mode, then select Multi-CD player. 2. Press key 7 to enter Mechanism Test mode. 3.

The signal reference potential, therefore, is connected to REFO(approx. 2.5V) instead of GND. If REFO and GND are connected to each other by mis- take during adjustments, not only will it be impossi- ble to measure the potential correctly, but the servo will malfunction and a severe shock will be applied to the pick-up. To avoid this, take special note of the fol- lowing. Do not connect the negative probe of the measuring equipment to REFO and GND together. It is especially important not to connect the channel 1 negative probe of the oscilloscope to REFO with the channel 2 negative probe connected to GND. Since the frame of the measuring instrument is usual- ly at the same potential as the negative probe, change the frame of the measuring instrument to floating sta- tus. If by accident REFO comes in contact with GND, immediately switch the regulator or power OFF. • Always make sure the regulator is OFF when connect- ing and disconnecting the various filters and wiring required for measurements. • Before proceeding to further adjustments and mea- surements after switching regulator ON, let the player run for about one minute to allow the circuits to stabi- lize. • Since the protective systems in the unit's software are rendered inoperative in test mode, be very careful to avoid mechanical and /or electrical shocks to the sys- tem when making adjustment. • Disc detection during tray extraction and return oper- ations is performed by means of the photo transistor in this unit. Consequently, if the inside of the unit is exposed to a strong light source with the outer casing removed for repairs or adjustment, the following mal- functions may occur: *Even with a disc loaded, the unit detects "no disc" and cannot start play. *Although a 12-cm disc is loaded, the unit detects "8cm disc" mistakenly. When the unit malfunctions this way, either re-posi- tion the light source, move the unit or cover the photo transistor. • During exchanging discs, do not press the keys for the discs to be exchanged. 2) Test Mode This mode is used for adjusting the CD mechanism module of the device. • Test mode starting procedure Reset while pressing the 4 and 6 keys together. • Test mode cancellation Switch ACC, back-up OFF. • If the 8 or 9 key is pressed while focus search is in progress, immediately turn the power off (otherwise the actuator may be damaged due to the lens stuck). • Jump operation of TRs other than 100TR continues after releasing the key. CRG move and 100TR jump operations are brought into the “Tracking close” sta- tus when the key is released. • Powering Off/On resets the jump mode to “Single TR (91)”, the RF AMP gain setting to 0 dB, and the auto- matic adjustment value to the initial value. • During exchanging discs, do not press the keys for the discs to be exchanged.

When normal: The “Test mode” guidance will be output. If any trouble is present: The following frequency of “pee” sounds will be repeated depending on type of the given error. When this sound is ended, you can repeat the “pee” sounds all over again by pressing any key. If the self-check detected any error, you can’t proceed to further steps in the test mode. Return to the self- check 1 above. 3 times: Error A is detected. 4 times: Error B is detected. 5 times: Errors A and B are detected. 6 times: Error D is detected. 7 times: Errors A and D are detected. 8 times: Errors B and D are detected. 9 times: Errors A, B and D are detected. Where, A: Flash memory (static data area) check-sum error. B: Communication error between DSP and RISC. D: External SRAM write/read error. * For details of the voice recognition specification, refer to the specification for the voice recognition LSI (AK2316). Step 2: Generating output of the built-in guidance word by word using the “+ key” or “- key”. 1 Press the “+ key” or “- key”. 2 This will output one word of the guidance. For the guidance list, refer to the “List of Guidance by Destination” (see page 52). * Repeating the above 1 operation allows you to sequentially output the total guidance sentence. Step 3: Check the IP-BUS for normal connection. (The guidance is available only when M/U is connected. If not connected, the guidance is not output. Even if M/U is not connected, however, you can proceed to Step 4 of the test.) 1 Depress the CALL key for less than 2 seconds. 2 The following guidance will be output notifying you whether or not the IP-BUS connection is appropriate: When appropriate: “IP BUS is OK”. When inappropriate: “IP BUS is No Good”. Step 4: Check whether registration with your voice is available. 1 Press the CALL key for 2 seconds minimum. 2 The guidance “Say name to be registered ....Pii” will be output. 3 Speak! (Speak any words to the microphone for 2.5 seconds maximum.) 4 When your voice is registered: What you spoke will be played back. When failed to register: The guidance “Buu” will be output. (Repeat the above step 1 through 4 until 4 words are registered.) 5 As your 4 words are registered, the guidance “Name is complete” will be output indicating the registration operation is finished. 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 52 CDX-P2050VC,P2050VN,P2050VS Step 5: Check whether the registered words are recognizable. (Make sure that 4 words are already registered in step 4 above.) 1 Press the CALL key for 2 seconds maximum. 2 The guidance “Make a request ...Puu” will be output. 3 Speak! (Speak one of 4 words registered.) 4 When successfully recognized: The guidance “Thank you” will be output. When failed to recognize: The guidance “Buu” will be output. * You can repeat above steps any number of times starting with 1. Step 6: Repeating the test mode from the first. (When the step 4 is complete, it is available to repeat the test mode again from Step 2.) 1 Press the CALL key for 2 seconds minimum. 2 The guidance “Test is finished” will be output. 3 Press the CALL key for less than 2 seconds. 4 The guidance “Test mode” will be output.

OPERATIONS AND SPECIFICATIONS 8.1 OPERATION Resetting the Microprocessor The microprocessor must be reset under the following conditions: When using this product for the first time after installation. When the machine fails to operate properly. • To reset the microprocessor, press the Reset button on this product with a pen tip or other pointed instrument. Note: • When changing batteries or unplugging the power cord, even if there is no power for an extended period, voice recordings remain in memory for up to about 24 hours at normal temperatures. However, if the inside of the car becomes hot, recordings may not remain in memory that long. • When the unit is switched on again, if you want to use the voice recordings as they are, do not press the Reset button. (If you press it, recordings are erased.) If the power does not switch on or if the compact disc player does not operate when the button on the multi-CD controller is pressed, or if the multi-CD controller display is incor- rect, press this button on the player with the tip of a pencil to restore normal operation. (This button is located inside the door.) Always press the Reset button on the multi-CD controller, too, after pressing this button. Note: • If the Reset button is pressed when the player contains a magazine or the ignition switch is set to the ON or ACC position, the CD title display and ITS memory are cleared.
