IMPORTANT SERVICE NOTES (FOR QT-CD210 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.

TO EXPOSED METAL PARTS
All check must be repeated with the AC line cord plug connection reversed. Any reading of 0.3 volt RMS (this corresponds to 0.2 milliamp. AC.) or more is excessive and indicates a potential shock hazard which must be corrected before returning the audio product to the owner.

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.

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.
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.

SDA)P4-2 These pins serve dual purposes as input or output pins for the serial
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.

89* NC/VPP NC Input/Output 90 /RST RESET Input Device's system reset signal input pin.
The device remains reset while RESET is held low and when RESET is
released back high, the CD unit becomes operational and the program
starts from address 0. Normally, a system reset is asserted when a voltage
of 2.7V or more is applied to VDD when it is at 0V (power-on reset).
Therefore, this pin must be pulled high when used for this purpose.

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.
