M/L AMP SYSTEM cannot use GGD1317.
Because, external connector is different from pioneer AMP and
M/L AMP(PIO:24P-20P,M/L:25P-16P).
Moreover, GGD1240 which is a previous jig cannot be used
(Because the signal array is different).
Therefore, when the head unit of the M/L AMP system is
repaired, pioneer AMP system is used.

6.4 CD ADJUSTMENT
A
1) Precautions
• This unit uses a single power supply (+5V) for the regulator. 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 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 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 usually at the same potential as the negative probe, change
the frame of the measuring instrument to floating status.
If by accident VREF comes in contact with GND,
immediately switch the regulator or power OFF.
2) Test Mode
This mode is used for adjusting the CD mechanism
module of the device.
• After pressing the EJECT key, do not press any other
key until the disk is completely ejected.
• If the TUNE UP or TUNE DOWN 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).
B
• Jump operation of TRs other than 100TR continues
after releasing the key. CRG move and 100TR jump
operations are brought into the “Tracking close” status 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
automatic adjustment value to the initial value.
C
• 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.
D
• The RFI and RFO signals are easy to oscillate because
of a wide band. When observing them, insert a resistor 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 incorrectly performed and recovery is disabled, the recovery is enabled by resetting a product or turning ACC
off to on.

6.5 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

• Checking Procedure
1. In test mode, load the disc and switch the 5V regulator on.
2. Using the TUNE UP and TUNE DOWN buttons, move the PU unit to the innermost track.
3. Press key 4 to close focus, the display should read "91". Press key 3 to implement the tracking balance adjustment the display should now read "81". Press key 4. 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.
E
• Hint
Reloading the disc changes the clamp position and may decrease the "wobble".

(1) Shifting to the New Test Mode
1 Turn on the current test mode by starting the reset from the key.
2 Select S-CD for the source through the specified procedure including use of the [CD]key,[DISC]key, and inserting the

"Low" when the FM stereo signals are received.
To be pulled up to the "VDD" at 47kΩ.
"High" when signals are received. To be pulled up to the "VDD" at 47kΩ
Meanwhile, 10kΩ should be used when taking diver FIX trigger from here
and "High: 0.9VDD or more" and "Low: 250mV or less".
(Should satisfy the diver IC specifications)
"High" when noise is received. Output for the RDS. GND at 47kΩ//1,800pF.
"High" when noise is received. Output for the RDS. GND at 36kΩ//330pF.
FM stereo "R-ch" signal output or AM audio output.
Add the specified de-emphasis constant.
FM stereo "L-ch" signal output or AM audio output.
Add the specified de-emphasis constant.
EEPROM write control. Writing permissible at "Low". Normally open.
SD bandwidth signal output. For detection of detuning data for the RDS.
AM detector output. r out < 100Ω
Power supply pin for the digital section.
DC 5V +/- 0.25V. Be careful about overlapping noise in the logic section.
11 DGND
Grounding for the digital section.

20 AMINI
AM audio input
The frequency response and the level are set by connecting an external CR
network with terminal AMIN as terminal AMDET. r in = 50kΩ
21 COMP O composite signal FM composite signal output. r out < 100Ω
22 VCC
power supply
Analog section power supply pin.DC 8.4V +/- 0.3V
23 LOCH
I
local high
FM local high pin. When seeking local high, apply 5V together with "LOCL".
24 FMLOCL I
FM local low
FM local low pin. When seeking local low, apply 5V to the base of the NPN
transistor with which the specified resistor is being connected to the emitter.
Keep it open in case of ordinary marketed models.
25 LOCL
I
local low
FM/AM local low pin. When seeking local low, apply 5V to the base of the
NPN transistor.Since this pin is exclusive for AM when the FMLOCL is in use,
do not drive it under FM.
26 RFGND
RF ground
Grounding for the antenna section.
27 FMANT I
FM antenna input FM antenna input. 75Ω. Surge absorber (DSP-201M-S00B) is necessary.
28 AMANT I
AM antenna input AM antenna input. High impedance.
Connect to the antenna through an L (LAU type) of 4.7µH.To cope with the
power transmission line hums, insert a series circuit consisting of an L
(a coil of about 100mH) + R (a resistor of 470 Ω to 2.2kΩ) between the GND.
