IMPORTANT SERVICE NOTES (FOR U.S.A. ONLY)
BEFORE RETURNING THE AUDIO PRODUCT
(Fire & Shock Hazard)
Before returning the audio product to the user, perform the
following safety checks.
1. Inspect all lead dress to make certain that leads are not
pinched or that hardware is not lodged between the chassis
and other metal parts in the audio product.
2. Inspect all protective devices such as insulating materials,
cabinet, terminal board, adjustment and compartment
covers or shields, mechanical insulators etc.
3. To be sure that no shock hazard exists, check for leakage
current in the following manner.
* Plug the AC line cord directly into a 120 volt AC outlet.
* Using two clip leads, connect a 1.5k ohm, 10 watt resistor
paralleled by a 0.15µF capacitor in series with all exposed
metal cabinet parts and a known earth ground, such as
conduit or electrical ground connected to earth ground.
* Use a VTVM or VOM with 1000 ohm per volt, or higher,
sensitivity to measure the AC voltage drop across the
resistor (See diagram).
* Connect the resistor connection to all exposed metal parts
having a return path to the chassis (antenna, metal cabinet,
screw heads, knobs and control shafts, escutcheon, etc.)
and measure the AC voltage drop across the resistor.

NOTES ON SCHEMATIC 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.
All rights reserved. Unauthorized duplicating, broadcasting and renting product is prohibited by law.

Power supply pins.
Normally, apply a voltage of 4.5 to 5.5V to VDD.
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).

4-bit CMOS I/O ports.
These ports can be set for input or output bit for bit by a program.
These pins can be pulled up to VDD or down to GND by program.
Therefore, they can be used as key input pins. Also, when they are set for
I/O port, a change of state in this input can be used to clear the clock stop
or wait mode.

5-bit CMOS I/O ports.
These ports can be set for input or output bit for bit by a program.
The P3-0 to P4-0 pins serve dual purposes as analog inputs for the internal
6-bit 4-channel A/D converters.
The internal A/D converters can complete conversion in 6 instruction cycles
using a successive approximation method. The required pins can be set for
A/D analog input bit for bit by a program. P3-0 can be set for reference
voltage input, and the internal power supply (MVDD) can be used for this
reference voltage.
The P4-0 pin serves dual purposes as a buzzer output pin.
The buzzer output can be selected from 8 frequencies, 0.625 to 3kHz.
Each selected frequency can be output in one of four modes: continuous,
single, 10Hz intermittent, and 10Hz intermittent at 1Hz interval.
Whether or not to use and how to control the A/D converter and buzzer all
can be set by a prograam.
In this unit, the terminal with asterisk mark (*) is (open) terminal which is not connected to the outside.

Function
3-bit CMOS I/O ports.
DI: Tuner Data Input pin.
DO: Tuner Data Output pin.
CL: Tuner/Volume Clock Output pin.
These ports can be set for input or output bit for bit by a program.
These pins serve dual purposes as input or output pins for the serial
interface circuit (SIO).
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.
Test mode control input pins.
The test mode is selected when these pins are set high and normal
operation is selected when they are low.
CE_(PLL): Tuner Chip Enable Input pin.
STB_(VOL): Volume Storobe Input pin.
P_MUTE: MUTE ON/OFF Output pin.
X-BASS: X-BASS ON/OFF Output pin.

Function
HOLD
Input
This pin is used to input a signal that requests or clears the hold mode.
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.
INTR
REMO-IN
Input
External interrupt input pin.
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).

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.
