SECTION 1SERVICING NOTES

NOTES ON HANDLING THE OPTICAL PICK-UPBLOCK OR BASE UNIT

The laser diode in the optical pick-up block may suffer electrostaticbreak-down because of the potential difference generated by thecharged electrostatic load, etc. on clothing and the human body.During repair, pay attention to electrostatic break-down and alsouse the procedure in the printed matter which is included in therepair parts.The flexible board is easily damaged and should be handled withcare.

NOTES ON LASER DIODE EMISSION CHECKThe laser beam on this model is concentrated so as to be focused onthe disc reflective surface by the objective lens in the optical pick-up block. Therefore, when checking the laser diode emission,observe from more than 30 cm away from the objective lens.

UNLEADED SOLDERBoards requiring use of unleaded solder are printed with the lead-free mark (LF) indicating the solder contains no lead.(Caution: Some printed circuit boards may not come printed with

the lead free mark due to their particular size)

: LEAD FREE MARKUnleaded solder has the following characteristics.

• Unleaded solder melts at a temperature about 40 °C higherthan ordinary solder.Ordinary soldering irons can be used but the iron tip has to beapplied to the solder joint for a slightly longer time.Soldering irons using a temperature regulator should be set toabout 350 °C.Caution: The printed pattern (copper foil) may peel away if

the heated tip is applied for too long, so be careful!• Strong viscosity

Unleaded solder is more viscou-s (sticky, less prone to flow)than ordinary solder so use caution not to let solder bridgesoccur such as on IC pins, etc.

• Usable with ordinary solderIt is best to use only unleaded solder but unleaded solder mayalso be added to ordinary solder.

RELEASING THE ANTITHEFT LOCKThe disc table lock function for the antitheft of an demonstrationdisc in the store is equipped.

Releasing Procedure :1. Press the I/1 button to turn the power on.2. Press the CD button to select “CD”.3. While pressing the x button, press the Z button until

“UNLOCKED” displayed on the fluorescent indicator tube(around 5 seconds).

Note: When “LOCKED” is displayed, the antitheft lock is not released byturning power on/off with the I/1 button.

is displayed on the fluorescent indicator tube momentarilyand press the [TUNING --] button, the message “ALL EQ MIN”is displayed on the fluorescent indicator tube momentarily.

5. Press the [ENTER] button, the message “ALL EQ FLAT” isdisplayed on the fluorescent indicator tube momentarily.

6. Turn the [VOLUME] knob clockwise, the message “VOLUMEMAX” is displayed on the fluorescent indicator tubemomentarily and turn the [VOLUME] knob counterclockwise,the message “VOLUME MIN” is displayed on the fluorescentindicator tube momentarily.

7. Press the [TAPE REC PAUSE/START] button to changed overVACS on/off.

8. Press the I/1 button to release from this mode, then cold resetis performed.

SECTION 4TEST MODE

COLD RESETThe cold reset clears all data including preset data stored in theRAM to initial conditions. Execute this mode when returning theset to the customer.Procedure:

1. Press three buttons of x , u and [GROOVE] simultaneously.2. The message “COLD RESET” is displayed on the fluorescent

indicator tube momentarily, then becomes standby states.

TUNING STEP CHANGE-OVERA step of AM tuning interval can be changed over between 9 kHzand 10 kHz.Procedure:

1. Press the I/1 button to turn the power on.2. Press the [TUNER/BAND] button to select “AM”.3. Press the I/1 button to turn the power off.4. Press two buttons of [TUNING +] and I/1 simultaneously.5. The message “AM 9K STEP” or “AM 10K STEP” is displayed

on the fluorescent indicator tube, and thus the tuning intervalis changed over.

CD SHIP (LOCK) MODEThis mode moves the optical pick-up to the position durable tovibration. Use this mode when returning the set to the customerafter repair.Procedure:

1. Press the I/1 button to turn the power on.2. Press the [CD] button to select “CD”.3. Press two buttons of u and I/1 simultaneously.4. The message “LOCK” is displayed on the fluorescent indicator

tube, and the CD ship mode is set.

Note:1. CD Block is basically constructed to operate without adjustment.2. Use YEDS-18 disc (3-702-101-01) unless otherwise indicated.3. Use an oscilloscope with more than 10 MΩ impedance.4. Clean the object lens by an applicator with neutral detergent when the

signal level is low than specified value with the following checks.5. Check the focus bias check when optical pick-up block is replaced.

FOCUS BIAS CHECK

Procedure :1. Connect oscilloscope to TP121 (RFI) and TP124 (VC) on the

CD board.2. Press the I/1 button to turn the power ON.3. Set disc (YEDS-18) on the tray and press the u button to

playback.4. Confirm that oscilloscope waveform is as shown in the figure

below. (eye pattern)A good eye pattern means that the diamond shape (◊) in thecenter of the waveform can be clearly distinguished.
