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.

hazard which must be corrected before returning the audio
product to the owner.

TURNING ON THE TEST MODE
The types of test mode for this microcomputer and specific test mode turning-on procedure are as follows. Only the unit key is used.
The remote control key is not valid. The power must be turned on while two keys are held down.
(1) CD test mode function
The power is turned while the (PRESET
) and STOP (TUNING
) keys are held down.
(2) Tuner test mode function
) and PAUSE (BAND) keys are held down.
The power is turned on while the (PRESET
(3) LCD test mode function
The power is turned on while the (PRESET
) and MEMORY keys are held down.
CD TEST MODE
When the CD test mode is turned on, the CD pickup is moved to the innermost periphery, and the following indication appears.
The operation of CD test mode is as follows.
Indication
(1) The CD pickup is moved with the unit UP key and DOWN key.
UP key: The pickup is slid to the outer periphery.
DOWN key: The pickup is slid to the inner periphery. However, when it reaches the innermost periphery, it does not move further
inward.
(2) When the PLAY key is pressed in stop state, the laser diode turns on if CD lid is closed.
Indication
(3) When the PLAY key is pressed in laser ON state, playback is started from the current position of pickup.
Indication
The current playback track No. and time are indicated.
(4) When the STOP key is pressed during playback, the laser goes out and playback is stopped, and the process returns to step
(1). (The pickup position does not change.)
(5) When the MEMORY key is pressed during playback, tracking servo ON/OFF is performed. (Even if the playback is stopped
in servo OFF state, the servo is turned on when the playback is restored.)
Indication
The current pickup position and time are indicated. (When the
pickup is moved with the UP/DOWN key, the time at that point
is indicated.)
Others
While the CD lid is open (LID-SW = "H"), the test mode is turned on but the operations of step (2) and subsequent steps are not
performed. The operation of step (1) is performed.

TUNER TEST MODE
The tuner test mode is intended to store the measurement frequency for adjustment and inspection in the preset memory CH
without frequency adjustment in the case of tuner adjustment in the production line.
When the power is turned on while the PRESET
(DOWN) key and BAND (PAUSE) key are held down together, the frequency
for adjustment measurement of destination (specified according to AREA terminal) is preset-stored in the preset memory CH. (The
frequency to be preset-stored for specific destination is as shown in the next page.)
–7–
QT-CD161/141
In the tuner test mode the band is FM, and the mode is FM STEREO in case of start-up.
As with the ordinary mode, when the PRESET
key is pressed for 1ch of preset memory CH, maximum CH is set. When the
PRESET
key is pressed for maximum CH of preset memory CH, 1ch is set.
The BAND key is valid. As in the ordinary mode, the band/FM MONO/STEREO mode can be switched.
To exit from the tuner test mode, turn off the power to the microcomputer.
Indication
The indication is the same as that of ordinary operation. However,
when the test mode is turned on, the indication shown left lights
for one second.

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.
