6. ADJUSTMENT

6.1 SINGLE CHECKING METHOD

6.1.1 FOR NAVIGATOR ITSELF

Single movement checking method when only navigation system is brought is as follows,
Usually, to display navigation, a special TV monitor (AVD-505) is required. However, the check is possible with the
TV monitor (NTSC) with RCA input terminal connected as follows,

1) Checkpoints : SYNC OUT·········Navigation screen signal line
Note) There are checkpoints on both sides of the PCB, but no silk display on the parts side (display only pattern

side).

2) Preparation :1) Series circuit of 75Ω and 470µF

2) RCA pin cord

3) TV monitor (NTSC)

4) Speaker with lamp receiving part

5) Power supply cord (CDE5704)

6) CD-ROM disc

3) Checking method :1) Display navigation video

Connect SYNC OUT point and GND on the PCB using RCA pin cord.
Connect 75Ω resistance and 470µF capacitor in series.

Note) For the checkpoints, there are rounds for both pattern side and parts side, but silk display is only on the

pattern side.

AVIC-505

- CD Test Mode

1)Precautions

· This unit uses a single power supply (+5V) for the
regulator. 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
mistake during adjustments, not only will it be
impossible 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 following.
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
usually at the same potential as the negative probe,
change the frame of the measuring instrument to
floating status.
If by accident REFO comes in contact with GND,
immediately switch the regulator or power OFF.

· Always make sure the regulator is OFF when
connecting and disconnecting the various filters and
wiring required for measurements.

· Before proceeding to further adjustments and
measurements after switching regulator ON, let the
player run for about one minute to allow the circuits
to stabilize.

· 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
system when making adjustment.

· Test mode starting procedure

1. Short-circuit the test point of the cdtest (IC801

Pin6) on the main unit with GND.

2. Press RESET and turn the power ON.

· Test mode cancellation

1. Turn the test point of the cdtest open.

2. Press RESET or switch ACC, back-up OFF.

· Disc detection during loading and eject operations is
performed by means of a photo transistor in this
unit.Consequently, if the inside of the unit is exposed
to a strong light source when the outer casing is
removed for repairs or adjustment, the following
malfunctions may occur.

*During PLAY, even if the eject button is pressed,the

disc will not be ejected and the unit will remain in
the PLAY mode.

*The unit will not load a disc.

When the unit malfunctions this way, either re­position the light source, move the unit or cover the
photo transistor.

· When loading and unloading discs during adjustment
procedures, always wait for the disc to be properly
clamped or ejected before pressing another key.
Otherwise, there is a risk of the actuator being
destroyed.

· Turn power off when pressing the button → or the
button ← key for focus search in the test mode. (Or
else lens may stick and the actuator may be
damaged.)

· SINGLE/4TRK/10TRK/32TRK will continue to operate
even after the key is released.Tracking is closed the
moment C-MOVE is released.

· JUMP MODE resets to SINGLE as soon as power is
switched OFF.

· Note :

Unlike previous CD mechanism modules the grating 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, REFOUT

· Disc · ABEX TCD-784

· Mode · TEST MODE

· Checking Procedure

1. In test mode, load the disc and switch the 5V regulator on.

2. Using the → and ← buttons, move the Pickup unit to the innermost track.

3. Press key ↑ to close focus, the display should read "91". Press key MENU to implement the tracking balance
adjustment the display should now read "8X". Press key ↑ 4 times. The display will change, returning to "8X" 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 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

- Average speed/increased speed switch-over
RF EQ circuit

In previous CD mechanism module circuits, the basic
average speed/increased speed RF EQ circuit was used,
but in the CXK5052 by changing over to an RF EQ
circuit which has been optimized in regards to the
playback speeds of both average speed and increased
speed, we are aiming at increased performance in
regards to skew offset, etc.

-

New externally-attached LPF circuit on the PLL
for increased speed

An LPF is needed to use the VCO contained within the
UPD63702AGF at double speed. To show the optimized
performance of the main IC UPD63702AGF, the circuit
configuration has been changed from the previous
externally-attached LPF circuits used with the
UPD63703GF (C203, R204, C205 etc.).
