ADJUSTMENT

TEST MODE

1. To enter test mode

While holding the "FM" key and preset "6" key,
reset the unit. All indication segments are ON at
the beginning of test mode.

2. To relese test mode

Simply reset the unit.
(NOTE) The test mode is not canceled by ACC
OFF, power OFF, momentary power down.

3. MD receiver test mode specification

Pressing the "Track Up" key jumps between
tracks in the following order.
No.7 / No.2 / No.13 / No.23 / No.30 /
No.34 / No.7
(Same as the beginning)
Pressing the "Track Down" key jumps to the pre­vious track to the being played.
Pressing the preset "1" key jumps to No.28
track. Again pressing the preset "1" key jumps
to No.22 track.

4. Audio adjustment

The volume is set to -10dB (which is shown as

30).
Loudness is OFF. CRSC becomes OFF regard­less of the functional excuse, too.
The BASS/TREBLE and BALANCE/FADER
controls can be set to the full boost/full cut and
full front/full rear and full right/full left respective­ly by pressing the "Track Up" / "Track Down"
keys.
Sound coordination (system Q) doesn't appear
for the Audio mode feed.

MDS-2500 Service Test Mode
(Manual Adjustment Mode)

In order to adjust the focus bias (balance) of
MDS-2500, automatic adjustment is conducted
at factory and bias value is written on the
E2PROM. When conducting adjustment on the
set, the data in the E2PROM is read. Therefore,
when changing the pickup for servicing, it is
necessary to conduct focus bias adjustment
again. If you are equipped with MDS-2000 AT3
Commander and jitter meter, it is possible to
use automatic adjustment. We have prepared
the service test mode (manual adjustment
mode) in case MDS-2000 AT3 Commander and
jitter meter are not available.

● Adjustment Procedure

(Note: During the adjustment procedure, be
sure to turn off the power supply to the set.)

1. Pull up the IC11 50pin (LADJ1 (Check
Land L1)) of the X33 Unit to BU5V (Check
Land BU 5).

2. Pull out the Check Land ARF of X33 Unit
and Check Land SAG (Servo GND) using
wires so these can be monitored with an
oscilloscope.

3. Turn the power on the set while resetting
the set.

* Adjustment should be conducted on total of
three places: low-reflection pit and groove of
the recordable disk and high-reflection pit of
the pre-mastered disk.

4. When the disk is loaded, the set enters the
adjustment mode.

● For Recordable Disk

5. With the "TNo. 1" display, low-reflection pit
beta play mode is entered. The display
section of the time code shows "50."

6. While monitoring ARF with an oscillos­cope, vary the focus bias with track up and
track down key.

7. In order to calculate the optimum values,
vary UP's and DOWN's and change the
values at which the ARF waves are dis­turbed or 3T waveform levels goes down
and calculate the center values for these.
For example, if values are 58 for the UP­side and 46 for the DOWN-side, the center
value 52 would be the optimum value.

8. After obtaining the optimum value, set it to
the value and press manual UP/DOWN
key, which will confirm the value.
(Normally, setting will be made by pressing
on the track UP/DOWN key.)

9. After adjusting the low-reflection pit in 8,
the pickup is automatically sent to the
groove area.

10. With the "TNo. 2" display, the groove beta

play mode is entered.

11. From this point on, it is the same as the

above 6, 7, and 8.

12. After adjustment on the groove area, the

set stops. Eject the disk and the adjust­ment is complete.

∗ Since there is only TOC area for low-

reflection pit, the play time is about 40
seconds. After the pit area, the set will
enter retry movement, during which
adjustments are not effective.

ADJUSTMENT

● For Pre-Mastered Disk

13. The set will enter high-reflection pit beta
play mode and adjustments in items
5,6,7, and 8 should be conducted.

14. After adjustments, the set stops. Eject
the disk and the adjustment is complete.

∗ During the test mode, rough adjust-

ments of the EF balance is conducted
at the same time. However, the adjust­ments are conducted automatically and
there is no need for outside operation.

● Service test mode display (Display on the
set)

PIT adjustment mode start [01-_:_]
PIT adjustment permission [01-_:50]
PIT adjustment in progress

(∗∗=adjustment data) [01-_:∗∗]

PIT confirmation

(Groove adjustment mode start) [02-_:_]
Groove adjustment permission [02-_:50]
Groove adjustment in progress

(∗∗=adjustment data) [02-_:∗∗]
Groove confirmation

(normal completion) [02-_:_]

● Error display (∗∗= Error status)
∗∗=03 : An error occurred while adjusting low

reflection pit EF balance adjustment

∗∗=04 : An error occurred while adjusting low

reflection pit focus bias

∗∗=05 : An error occurred while adjusting low

reflection pit E2PROM write

∗∗=19 : An error occurred while adjusting

groove EF balance

∗∗=20 : An error occurred while adjusting

groove focus bias

∗∗=21 : An error occurred while adjusting

groove E2PROM write

∗∗=35 : An error occurred while adjusting

high reflection EF balance

∗∗=36 : An error occurred while adjusting

high reflection focus bias

∗∗=37 : An error occurred while adjusting

high reflection E2PROM write

● Adjustment Parameter

Adjustment condition : Restart after setting
LADJ1 terminal to high
Adjustment Key : Track UP/DOWN key
Confirmation Key: Manual UP/DOWN key
(Depending on a set, press on adjustment
key)

Notes

1. After adjusting for a media, it must be
always confirmed. When another media is
adjusted without confirming it, E2PROM
data will be damaged.

2. When focus bias values are set to extreme
UP or DOWN, focus will come down. It
could be recovered by re-try, but there is a
possibility for errors and key may become
ineffective. When this happens, reset and
start again.

(The same will happen when data is con­firmed with an extreme value.)

3. E-99
E-99 is a mechanical error but E-99 is also
display when E2PROM data is damaged.
There is a possibility for destroying
E2PROM data when power supply is on
(BU UP) when installing or removing
wires. Therefore, this must be done while
power supply is off (BU UP off).
The same applies for pulling or inserting
card cords (flexible cords) that come in
contract with the mechanism. (Normal
operation cannot be expected by setting
TO terminal to high, as with MDS-100.)

4. About E2PROM
E2PROM contains various initial data for
MD and DSP. Adjustment data re-writes
part of the data while making adjustments.
Therefore, it must be noted that, for those
with no initial data, an error could occur.
Also, as MD mechanism is made to
accommodate LP, the E2PROM capacity
is changed from 1k to 2k. Since internal
tables are different, it must be noted that
those used with MDS-2000, MDS-2100,
and MDS-2200 systems are not usable.

CAUTION : For continued safety, replace safety critical components only with
manufacturer's recommended parts (refer to parts list).

Indicates safety critical components. To reduce the risk of electric shock,
leakage-current or resistance measurements shall be carried out (exposed
parts are acceptably insulated from the supply circuit) before the appliance is
returned to the customer.

• DC voltages are as measured with a high impedance voltmeter. Values
may vary slightly due to variations between individual instruments or/and
units.

CAUTION : For continued safety, replace safety critical components only with manufacturer's recommended parts (refer to parts
list).

Indicates safety critical components. To reduce the risk of electric shock, leakage-current or resistance measurements shall be

carried out (exposed parts are acceptably insulated from the supply circuit)
before the appliance is returned to the customer.

• DC voltages are as measured with a high impedance voltmeter. Values

may vary slightly due to variations between individual instruments or/and units.
