SAFETY PRECAUTION FOR SERVICE MANUAL

Precaution to be taken when replacing and servicing the Laser Pickup.

The AEL (Accessible Emission Level) of Laser Power Output for this model is specified to be lower than Class I Requirements.
However, the following precautions must be observed during servicing to protect your eyes against exposure to the Laser beam.
(1) When the cabinet has been removed, the power is turned on without a compact disc, and the Pickup is on a position outer than

the lead-in position, the Laser will light for several seconds to detect a disc. Do not look into the Pickup Lens.
(2) The Laser Power Output of the Pickup inside the unit and replacement service parts have already been adjusted prior to shipping.
(3) No adjustment to the Laser Power should be attempted when replacing or servicing the Pickup.
(4) Under no circumstances look directly into the Pickup Lens at any time.
(5) CAUTION - Use of controls or adjustments, or performance of procedures other than those specified herein may result in

hazardous radiation exposure.

NOTES ON SCHEMA TIC DIAGRAM

• Resistor:
To differentiate the units of resistors, the symbol as K and M
are used: the symbol K means 1000 ohm and the symbol M
means 1000 kohm and the resistor without any symbol is an
ohm resistor. The resistor designated "Fusible" is a fuse type
resistor

• Capacitor:
To indicate the unit of capacitor, a symbol P is used: this
symbol P means micro-micro-farad and the unit of the capacitor
without such a symbol is microfarad. As to electrolytic capacitor,
the expression “capacitance/withstand voltage” is used.
(CH), (TH), (RH), (UJ): Temperature compensation
(ML): Mylar type
(P.P.): Polypropylene type

• The indicated voltage in each section is the one measured by
Digital Multimeter between such a section and the chassis
with no signal given.

TROUBLESHOOTING (CD SECTION)

When the CD does not function

When the CD section does not operate when the objective lens of the optical pickup is dirty, this section may not operate. Clean
the objective lens, and check the playback operation. When this section does not operate even after the above step is taken,check
the following items.
Remove the cabinet and follow the troubleshooting instructions.
"Track skipping and/or no TOC (Table Of Contents) may be caused by build up of dust other foreign matter on the laser pickup
lens. Before attempting any adjustment make certain that the lens is clean. If not, clean it as mentioned below."

Turn the power off.
Gently clean the lens with a lens cleaning tissue and a small amount of isopropyl alcohol.
Do not touch the lens with the bare hand.

Dust gradually accumulates on the objective lens during use, and it may degrade performance.
To avoid this problem, use a cleaning disc designed for CD optical pickup lenses.

HOW TO USE

1. Using the brush in the cleaner cap, apply 1 or 2 drops of the cleaning fluid to the brush on the CD cleaner disc which has
the mark next to it.

2. Place the CD cleaner disc onto the CD disc tray with the brush side down, then press the play button.

3. You will hear music for about 20 seconds and the CD player will automatically stop. If it continues to turn, press the stop button.

CAUTION

The CD lens cleaner should be effective for 30 - 50 operations, however if the brushes become worn out earlier then please
replace the cleaner disc.
If the CD cleaner brushes become very wet then wipe off any excess fluid with a soft cloth.
Do not drink the cleaner fluid or allow it to come in contact with the eyes. In the event of this happening then drink and / or
rinse with clean water and seek medical advice.
The CD cleaner disc must not be used on car CD player or on computer CD ROM drives.

Function

In a backup state (when the CKSTP instruction executed), the device's
current consumption is reduced to 1µA or less, allowing for the supply
voltage to be lowered to 2.0V.
The device is reset and the program starts from address 0 when a voltage
of 2.7V or more is applied to this pin when it is at 0V (power-on reset).

I/O port, a change of state in this input can be used to clear the clock stop
or wait mode.

32* (SCK/SCL) NC Input/Output interface circuit (SIO).

P4-3 The SIO is a 2-wire/3-wire compatible serial interface. 4 or 8 bits of serial

data, beginning with the MSB or LSB, are serially output from the SO/SDA,
pin at each clock edge on the SCK/SCL pin, and the data on S11 or S12
pin is serially input to the device.
The serial clock (SCK/SCL) allows selection between the internal (450/225/
150/75 kHz) and external sources and a selection of the active edge, rise or
fall. Moreover, since the clock and data can be output via Nch open-drain
outputs, variouts, device controls and communication between controllers
can be greatly facilitated.
When an SIO interrupt is enabled, an interrupt is generated at completion
of SIO execution and the program jumps to address 4.
All inputs to SIO contain a Schmitt trigger circuit.

Function

Normally, use this pin for CD mode select signal input or battery detection
signal input.
There are two hold modes: clock stop mode (crystal oscillator turned off)
and a wait mode (CPU stopped). These modes are entered by executing
the CKSTP and WAIT instructions, respectively.
The clock stop mode can be requested by a programmed input: low level
detection on HOLD pin or forced execution, and can be cleared by
detecting a high on the HOLD pin or a change of state in its input signal.
When the CKSTP instruction is executed, the clock generator and the CPU
stop operating and the device is placed in a memory backup state. During
this state, the device's current consumption is reduced to 1µA or less.
At the same time, the display output and CMOS output ports are
automatically set low, and the Nch open-drain outputs are turned off.
The wait mode is executed regardles of the input state on the HOLD pin,
with the device's current consumption reduced.
This mode is cleared by a change of state in the HOLD input.

When the interrupt facility is enabled and a pulse of 1.11 to 2.22µs in
duration is applied to this pin, an interrupt is generated and the program
jumps to address 1. Input logic and the active edge (rise or fall) can be
selected for each interrupt input.
Also, the internal 8-bit time clock can be chosen for this interrupt input, in
which case it is possible to count pulses or generate an interrupt at a given
pulse count (address 3).

controller's system clock. Connect a 4.5MHz or 75kHz crystal resonator to
the MXO and MXI pins. Since these pins do not contain internal feedback
resistors, etc, an amp resistor or output resistor must be added external to
the chip.
When using the clock generated by the CD unit's crystal oscillator for
clocking the entire device operation, fix the MXI pin to the GND level.
Oscillation is stopped by executing a CKSTP instruction.
Select the crystal oscillator and control its operation by a program.

In a backup state (when the CKSTP instruction executed), the device's
current consumption is reduced to 1µA or less, allowing for the supply
voltage to be lowered to 2.0V.
The device is reset and the program starts from address 0 when a voltage
of 2.7V or more is applied to this pin when it is at 0V (power-on reset).

After a system reset and after deassertion of a clock stop instruction, the
VEE voltage is output and the DISP OFF bit is set to 0 before common
signals are output.

In this unit, the terminal with asterisk mark (*) is (open) terminal which is not connected to the outside.
