SAFETY PRECATION FOR
SERVICE MANUAL
Precaution to be taken when replacing and servicing the Laser Pickup.
The ael (ACCESSIBLE EMMISSION LEVEL) of the laser power output is less than class 1 but the laser component is capable of emitting radiation exceeding the limit for class 1. Therefore it is important that the following precautions are observer during servicing to protect your eyes against exposure to the laser beam.
(1) When the cabinet is removed, the power is turned on
without a compact disc in position and the pick-up is on the outer edge the laser will light for several seconds to detect a disc. Do not look into the pick-up lens.
(2) The laser power output of the pick-up unit and replacement
service parts are all factory pre-set before shipment. Do not attempt to re-adjust the laser pick-up unit during
replacement or servicing.
(3) Under no circumstances stare into the pick-up lens at any
time.
(4) CAUTION-USE of controls or adjustments, or pereformance
of procedures other than those specified herein may result in hazardous radiation exposure.

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
The power is turned on while the (PRESET ) and PAUSE (BAND) keys are held down.
(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
(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
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.
The current playback track No. and time are indicated.
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.)

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.)
– 8 –
QT-CD141H/161H/162H
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

Note: The unit shown in table is Hz. K is x1000. M is x1,000,000. The slash indicates that data are not stored in the memory. FM is stereo mode.
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 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. All rights reserved. Unauthorized duplicating, broadcasting and renting product is prohibited by law.
