For pickup unit(CXX1480) handling, please refer to"Disassembly"(see page 38). During replacement, handling precautions shall be taken to prevent an electrostatic discharge(protection by a jumper-solder). 2. During disassembly, be sure to turn the power off since an internal IC might be destroyed when a con- nector is plugged or unplugged. 3. Please checking the grating after changing the pickup unit(see page 35). 4. In this product, because the memory capacity of the microcomputer is insufficient, the test mode is not installed. However grating of the pickup unit can be confirmed. 1. SAFETY INFORMATION 2.

ADJUSTMENT 6.1 CD ADJUSTMENT 1) Precautions • This unit uses a single power supply (+5V) for the reg- ulator. The signal reference potential, therefore, is connected to VREF(approx. 2.1V) instead of GND. If VREF 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 VREF and GND together. It is especially important not to connect the channel 1 negative probe of the oscilloscope to VREF 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 VREF 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. • The RFI and RFO signals are easy to oscillate because of a wide band. When observing them, insert a resis- tor of about 1 kΩ to the series. • This equipment will not guarantee the load ejection operation when the mechanical unit is turned upside down. In particular, if the ejection operation is incor- rectly performed and recovery is disabled, the recov- ery is enabled by resetting a product or turning ACC off to on. 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. • After pressing the EJECT key, do not press any other key until the disk is completely ejected. • If the ] or [ key is pressed while focus search is in progress, immediately turn the power off (otherwise the actuator may be damaged due to adhesion of the lenses). 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 35 DEH-1450,1450B • Note : The grating angle of the PU unit cannot be adjusted after the PU unit is changed. The PU unit in the CD mecha- nism module is adjusted on the production line to match the CD mechanism module and is thus the best adjusted PU unit for the CD mechanism module. Changing the PU unit is thus best considered as a last resort. However, if the PU unit must be changed, the grating should be checked using the procedure below. • Purpose : To check that the grating is within an acceptable range when the PU unit is changed. • 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 taking a long time for track searching. • Method : • Measuring Equipment • Oscilloscope, Two L.P.F. • Measuring Points • E, F, VREF • Disc • ABEX TCD-784 • Mode • TEST MODE • Checking Procedure 1. In test mode, load the disc and switch the 5V regulator on. 2. The display will change, returning to "81" on the fourth press. 3. 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. 4. If the phase difference is determined to be greater than 75° try changing the PU 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 Reloading the disc changes the clamp position and may decrease the "wobble". 100kΩ 390pF 100kΩ 390pF E VREF F VREF Xch Ych L.P.F.

Recalling equalizer curves There are six stored equalizer curves which you can easily recall at any time. Here is a list of the equalizer curves: Display Equalizer curve SBASS Super bass PWRFL Powerful NTRL Natural VOCAL Vocal CSTM Custom FLAT Flat • CSTM is an adjusted equalizer curve that you create. • When FLAT is selected no supplement or correction is made to the sound. This is use- ful to check the effect of the equalizer curves by switching alternatively between FLAT and a set equalizer curve. Press EQ to select the equalizer. • If the equalizer has been previously set to an equalizer curve other than PWRFL then the title of that previously selected equalizer curve will be displayed, such as SBASS, NTRL, VOCAL, CSTM, or FLAT. Adjusting equalizer curves You can adjust the currently selected equal- izer curve setting as desired. Adjusted equalizer curve settings are memorized in CSTM. 1 Press AUDIO to select the equalizer mode. Press AUDIO until EQ appears in the display. 2 Select the band you want to adjust with 2/3. L (low) —M (mid) —H (high) 3 Press 5 or ∞ to adjust the equalizer curve. Each press of 5 or ∞ increases or decreases the equalizer curve respectively. • +6 – –6 is displayed as the equalizer curve is increased or decreased. • The actual range of the adjustments are different depending on which equalizer curve is selected. Note • If you make adjustments when a curve other than CSTM is selected, the newly adjusted curve will replace the previous curve. Then a new curve with CSTM appears on the display while selecting the equalizer curve. 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 DEH-1450,1450B 56 + ≠ + ≠ + ≠ + ≠ + ≠ + ≠ V 23. iolet 12. 25.
