6. ADJUSTMENT
CHECKING THE GRATING AFTER CHANGING THE PICKUP UNIT
· Note : The grating angle of the PU unit cannot be adjusted after the PU unit is changed. The PU unit in the CD mechanism 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 · Measuring Points · Disc · Mode

· Oscilloscope, Two L.P.F. · E, F, REFOUT · ABEX TCD-784 · TEST MODE

· Checking Procedure 1. In test mode, load the disc and switch the 5V regulator on. 2. Using the FWD and REV buttons, move the PU unit to the innermost track. 3. Press key B to close focus, the display should read "91". Press key D to implement the tracking balance adjustment the display should now read "81". Press key B 4 times. The display will change, returning to "81" on the fourth press. 4. As shown in the diagram above, monitor the LPF outputs using the oscilloscope and check that the phase difference 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 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 average angle. · Hint Reloading the disc changes the clamp position and may decrease the "wobble".

7. GENERAL INFORMATION
7.1 DIAGNOSIS 7.1.1 TEST MODE
- CD Test Mode
1) Precautions on Adjustment · The unit employs a single voltage (+5V) for the regulator, thus the reference potential of the signal is RFOUT (approximately 2.5V) rather than GND. Inadvertent contact of REFOUT and GND during adjustment can result not only in disabling normal potential measurement but also in exposing the pickup to strong impacts due to malfunctioning of the servo. Therefore, you are requested to observe the following precautions. · Make sure that the negative probe of the measuring instrument is not connected to RFOUT or GND. Special care must be exercised so that the channel 1 negative probe may not be connected to the oscilloscope and the channel 2 negative probe to GND. Since the frame of the measuring instrument is usually at the same potential as the negative probe, the frame of the measuring instrument must be changed to floating status. When RFOUT is inadvertently connected to GND, you must immediately turn off the regulator or power supply. · The regulator must be turned off before mounting or dismounting filters or wiring materials. · You should not start adjustment or measurement immediately after the regulator is turned on. It is recommended to run the player for approximately one minute so that it may stabilize. · When the test mode is turned on, various protective functions from the software become unavailable. Thus, you must make sure that undesirable electric or mechanical shocks are not be given to the system. · This model employs a photo-transistor for detecting discs at their loading or ejection. Thus, if its outer case is removed during repair work and internal parts are exposed to light of strong intensity, malfunctions including the following can result: The eject button becomes inoperable during play. Pressing the eject button does not eject a disc and play is continued. Loading becomes unavailable. If a malfunction is recognized, appropriate remedial actions must be taken. Such actions include changing the light source position, changing the unit position and applying a cover to the photo-transistor. · When you press the [EJECT] key to eject a disc, you must not touch any other key until the ejection is complete. · If you press the [FWD] or [REV] for the focus search in the test mode, you must turn the power off immediately. (Otherwise, the lens will be forced to stick to the top or bottom, potentially resulting in the burning of the actuator.) 2) Description of the Test Mode Adjustment of this unit is done in parallel with the CD control unit (KEH-M9100ZRN/EW), thus key operations for adjustments are done from the unit. Taking the example of the KEH-M9100ZRN/EW, the following describes how to turn on the test mode and operate the keys. The keys referred to in the following are those used on the KEH-M9100ZRN/EW. · Turning on the Test Mode Press the [AF] and [6] keys simultaneously to turn on the ACC and the backup. · Ending the Test Mode When ACC or Back up is off, the test mode is canceled. · Operation of TR JUMPs (except 100TR) continues after your finger has left the key. CRG MOVE and 100TR JUMP are forced to the tracking close mode as soon as the key is released. · Turning the power on or off resets the JUMP MODE to the Single TR.

Note: Sound is unavailable even after the tracking has been closed (this trouble results when the IC for the STS is not controlled in the test mode). Note: When you pressed the [FWD] or [REV] key during the Focus Search, you must turn the power off immediately (otherwise, the lens can stick resulting in actuator damages).

- Precautions
*4 Before performing the elevation, make sure that the CAM SW (switch) is set to a position between 22 and 20. As a rule, driving of the ELV MOTOR must be started immediately after the CAMSW indication has changed from 22 to 20. When driving the CAM MOTOR in 31 30 10 (in REV direction), the elevation position must be at the EJECT/LOAD position (the top position).

- Operating Procedures for Ejecting a Clamped Disc
1 Select CAM MOTOR[73] , then press the REV direction while the disc is being clamped (CAMSW state is 32). The CAMSW status indication sequentially changes through 32332322. 2 When the disc to be ejected is not identical with the disc being clamped, select the ELV MOTOR[74] in the vicinity of where the display changes from 22 to 20, then match the elevation to the disc to be ejected according to the following procedures: After selecting ELV MOTOR[74], lower the elevation until the ELV position display becomes 01 (1st disc) using the REV direction. Drive the elevation up until the display is changed to 10. This is the elevation where the second disk is situated. The next display of 10 tells you the elevation of the 3rd disc. Repeating this operation allows you to establish an elevation matching each disc. (When the elevation is driven from the 1st through 6th disc, the status display changes as 0111101110111011101110.) (When the disc to be ejected coincides with the disc being clamped, the above operations are not necessary.) 3 Select the CAM MOTOR [73] and then, using the REV direction, drive it until the display changes from 20 (or 22) to 21 and 31. 4 Select the ELV MOTOR [74], then drive the tray of the disc to be ejected up to the EJECT/LOAD position (using the FWD direction). 5 Select the CAM+LOAD MOTOR [76], then drive it in the REV direction until the display changes from 31 to 30 and 10. The door will open immediately before the display changes to 10 and part of the disc will be pushed out. 6 When 10 is displayed, select the LOAD MOTOR [75], then drive it in REV direction until the disc is completely ejected.
