LABEL CHECK (For DLXJ/NC types)

THIS PIONEER APPARATUS CONTAINS

IMPORTANT

LASER OF CLASS 1.
SERVICING OPERATION OF THE APPARATUS
SHOULD BE DONE BY A SPECIALLY
INSTRUCTED PERSON.

LASER DIODE CHARACTERISTICS
MAXIMUM OUTPUT POWER: 1.3 mW
WAVELENGTH: 790 nm ± 25 nm

Additional Laser Caution

1.Laser Interlock Mechanism
The position of the switch (S8501) for detecting loading
state is detected by the system microprocessor, and
the design prevents laser diode oscillation when the
switch (S8501) is pressed physically.
Thus, the interlock will no longer function if the switch (S8501)
is released physically and deliberatery.

The interlock also does not function in the test mode ∗.
Laser diode oscillation will continue, if pin 62 of
LA9240ML (IC8101) on the CD ASSY mounted on the

Printed on the Rear Panel

2

$M Loading Mechanism assembly is connected to GND,
or else the terminals of Q8101 are shorted to each other
(fault condition).

2.When the cover is opened, close viewing of the objective
lens with the naked eye will cause exposure to a Class
1 laser beam.

5. PCB PARTS LIST

NOTES:

LIST OF HOLE PCB ASSEMBLIES

Parts marked by "NSP" and can not be supplied.

•

The mark found on some component parts indicates the importance of the safety factor of the part.

•

Therefore, when replacing, be sure to use parts of identical designation.
When ordering resistors, first convert resistance values into code form as shown in the following examples.

•

Ex.1 When there are 2 effective digits (any digit apart from 0), such as 560 ohm and 47k ohm (tolerance is shown by J=5%,
and K=10%).

560 Ω→56 × 10
47k Ω→47 × 10

1

→ 561 ........................................................RD1/4PU 5 6 1 J

3

→ 473 ........................................................RD1/4PU 4 7 3 J

0.5 Ω→R50 .....................................................................................RN2H

1 Ω→1R0 ..................................................................................... RS1P 1 R 0 K

Ex.2 When there are 3 effective digits (such as in high precision metal film resistors).

5.62k Ω→ 562 × 10

1

→ 5621 ...................................................... RN1/4PC 5 6 2 1 F

Electrical Adjustment

Check the following before starting.

(1) Confirm that the tape speed adjustment has been completed.
(2) Clean the heads and demagnetize them using a head eraser.
(3) Set the measurement level to 0 dBV = 1 Vrms.
(4) Use the specified tape for adjustment. Use the labeled (A)
side of the test tape.

STD-331E : For playback check
STD-632 : Normal blank tape

(5) Provide yourself with the following measuring devides:

AC millivoltmeter

•

Low-frequency oscillator

•

Attenuator

•

Oscilloscope

•

(6) Adjust both right and left channels unless otherwise specified.
(7) Turn the DOLBY NR switch off unless otherwize specified.
(8) Warm up the unit for several minutes before adjustment.
In particular, be sure to warm up the unit in the REC/PLAY
mode for 3 to 5 minutes before starting recording/playback
frequency characteristics adjustment.
(9) Always follow the indicated adjustment order.
Otherwise, a complete adjustment may not be achieved.

Playback Adjustment (Decks I and II)

(1) Head Azimuth Adjustment
(2) Playback Level Adjustment

Recording Adjustment (Deck I)

(1) Bias Oscillation Frequency Adjustment
(2) Recording Bias Adjustment
(3) Recording Level Adjustment.
(4) ALC Operation Check

* As the reference recording level is 250nwb/m for STD-331E, the
recording level will be higher by 4 dB for STD-331B (160nwb/m).
When adjusting, pay carefull attention to the type of tape used.
