Precaution to be taken when replacing and servicing the Laser Pickup.The AEL (Accessible Emission Level) of Laser Power Output for this model is specified to be lower than Class I Requirements.However, the following precautions must be observed during servicing to protect your eyes against exposure to the laser beam.(1) When the cabinet has been removed, the power is turned on without a compact disc, and the Pickup is on a position
outer than the lead-in position, the Laser will light for several seconds to detect a disc. Do not look into the Pickup Lens.(2) The Laser Power Output of the Pickup inside the unit and replacement service parts have already been adjusted prior
to shipping.(3) No adjustment to the Laser Power should be attempted when replacing or servicing the Pickup.(4) Under no circumstances look directly into the Pickup Lens at any time.(5) CAUTION - Use of controls or adjustments, or performance of procedures other than those specified herein may result
in hazardous radiation exposure.
SAFETY PRECAUTION FOR SERVICE MANUAL
VARO ! Avattaessa ja suojalukitus ohitettaessa olet alttiina näkymättömälle lasersäteilylle. Älä katso säteeseen.VARNING! Osynlig laserstralning när denna del är öppnad och spärren är urkopplad. Betrakta ej strälen.

initial location of wires.Since the screws are small, incorrect fixing may result inmalfunction.
3. When repairing, pay utmost attention to static electricityof IC.

[ T E S T ](7) Press the "BASS" button, and press twice the "SKIP DOWN" button.
[ E E P R O M ](8) Perform the operation to display "EEPROM SETTING MODE CHART", compare the EEPROM DATA LIST with the display,
and set according to the EEPROM DATA LIST with the VOL UP or VOL DOWN key. (9) Set the temperature reference. (Refer to the Temperature Reference Setting Method.) (10) Set according to the EEPROM DATA LIST. (11) Press the Stop button.
[ T E S T ] (12) Press the Stop button. (13) After data is written in EEPROM, turn off power . (14) Restore protection of EEPROM.
2. Temperature reference setting method[1] Measurement, calculation and setting procedure
(1) Set the TEST mode. • Set TEST 1, 0 = '01', and turn on power (or set PLAY ON in standby state).(2) Start the EEPROM mode 'Temp' menu. • Key operation in order of BASS, SKIP-DOWN x 2 times, PLAY, PLAY in the test mode STOP state. • 'TM$$%%' is displayed. ($$= Temperature code, %% = Temperature reference)(3) Once press SKIP-UP, and determine the displayed microcomputer TEMP input AD value. • 'TPin##' is displayed. (## = TEMP input AD value)(4) At the ambient temperature, determine the temperature corrected value from the temperature measurement value
correction table.(5) Determine the temperature reference, using the following formula. • Temperature reference = Microcomputer TEMP input AD value + Temperature corrected value(6) Set the temperature reference value by button operation , and check whether the temperature code indication corresponds to "Temperature
Code Identification Table".

NOTES ON SCHEMATIC DIAGRAM
• Resistor:To differentiate the units of resistors, such symbol as K andM are used: the symbol K means 1000 ohm and the symbolM means 1000 kohm and the resistor without any symbol isohm-type resistor. Besides, the one with “Fusible” is a fusetype.
• Capacitor:To indicate the unit of capacitor, a symbol P is used: thissymbol P means micro-micro-farad and the unit of thecapacitor without such a symbol is microfarad. As to electro-lytic capacitor, the expression “capacitance/withstand volt-age” is used.(CH), (TH), (RH), (UJ): Temperature compensation(ML): Mylar type
• The indicated voltage in each section is the one measuredby Digital Multimeter between such a section and the chas-sis with no signal given.
• Parts marked with “ ” ( ) are important formaintaining the safety of the set. Be sure to replace theseparts with specified ones for maintaining the safety andperformance of the set.

When does not functionWhen the CD section does not operate When the objective lens of the optical pickup is dirty,this section may not operate.Cleanthe objective lens,and check the playback operation.When this section does not operate even after the above step is taken,checkthe 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.
Is the power supply turned on when the remote controlbutton or main unit button is pressed? No
Perform the check stated in item "Power is not turned onwhen the PLAY button is pressed".
