SAFETY CHECK-OUTAfter correcting the original service problem, perform the following safety checks before releasing the set to the customer: Check the antenna terminals, metal trim, metallized knobs, screws, and all other exposed metal parts for AC leakage. Check leakage as described below.

The release method of a CD disc tray LOCK functionThere is a disc lock function for the disc theft prevention for a demonstration at a shop front in this machine. Procedue: 1. Press the ?/1 button to turn the set on. 2. Press two buttons of x and Z (EJECT) simultaneously for five seconds. 3. The message LOCKED is displayed and the tray is locked. (Even if exiting from this mode, the tray is still locked.) 4. Press two buttons of x and Z (EJECT) simultaneously for five seconds again. 5. The message UNLOCKED is displayed and the tray is unlocked. 6. To exit from this mode, press the ?/1 button to turn the set off.Unleaded solder Boards requiring use of unleaded solder are printed with the leadfree 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.)

LEAKAGEThe AC leakage from any exposed metal part to earth ground and from all exposed metal parts to any exposed metal part having a return to chassis, must not exceed 0.5 mA (500 microamperes). Leakage current can be measured by any one of three methods. 1. A commercial leakage tester, such as the Simpson 229 or RCA WT-540A. Follow the manufacturers instructions to use these instruments. A battery-operated AC milliammeter. The Data Precision 245 digital multimeter is suitable for this job. Measuring the voltage drop across a resistor by means of a VOM or battery-operated AC voltmeter. The limit indication is 0.75 V, so analog meters must have an accurate low-voltage scale. The Simpson 250 and Sanwa SH-63Trd are examples of a passive VOM that is suitable. Nearly all battery operated digital multimeters that have a 2V AC range are suitable.

: LEAD FREE MARK Unleaded solder has the following characteristics. Unleaded solder melts at a temperature about 40C higher than ordinary solder. Ordinary soldering irons can be used but the iron tip has to be applied to the solder joint for a slightly longer time. Soldering irons using a temperature regulator should be set to about 350C. 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 viscous (sticky, less prone to flow) than ordinary solder so use caution not to let solder bridges occur such as on IC pins, etc. Usable with ordinary solder It is best to use only unleaded solder but unleaded solder may also be added to ordinary solder.

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT The laser diode in the optical pick-up block may suffer electrostatic break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts. The flexible board is easily damaged and should be handled with care. NOTES ON LASER DIODE EMISSION CHECK The laser beam on this model is concentrated so as to be focused on the disc reflective surface by the objective lens in the optical pickup block. Therefore, when checking the laser diode emission, observe from more than 30 cm away from the objective lens. Laser component in this product is capable of emitting radiation exceeding the limit for Class 1.

CAUTION Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure. Notes on chip component replacement Never reuse a disconnected chip component. Notice that the minus side of a tantalum capacitor may be damaged by heat. Flexible Circuit Board Repairing Keep the temperature of soldering iron around 270C during repairing. Do not touch the soldering iron on the same conductor of the circuit board (within 3 times). Be careful not to apply force on the conductor when soldering or unsoldering. 5-1. Block Diagrams PANEL Section 22 MAIN Section 23 BD/DRIVER Section 24 SUB-WOOFER Section 25 5-2.

Press ?/1 button to turn the set ON. 2. Select the function TUNER, and press TUNER/BAND button to select the BAND AM. 3. Press ?/1 button to turn the set OFF. 4. Press PLAY MODE/TUNING MODE and ?/1 buttons simultaneously, and the display of fluorescent indicator tube changes to AM 9 k STEP or AM 10 k STEP, and thus the channel step is changed over. [Cold Reset] The cold reset clears all data including preset data stored in the RAM to initial conditions. Execute this mode when returning the set to the customer. Procedure: 1. Press three buttons x , PLAY MODE/TUNING MODE , and DISC 1 simultaneously. 2. The fluorescent indicator tube displays COLD RESET and the set is reset. [Aging Mode] This mode can be used for operation check of CD section and tape deck section. If an error occurred: The aging operation stops and is displayed status. If no error occurs: The aging operation continues repeatedly. 1. Operating method of Aging Mode Press ?/1 button to turn the set ON and select CD of the function. 1) Set three discs in tray. Press the PLAY MODE/TUNING MODE button to set the ALL DISCS mode, and the PRESET EQ button to REPEAT off. 2) Load the tapes recording use into both decks. 3) Press three buttons x , PLAY MODE/TUNING MODE , and EX-CHANGE simultaneously. 4) Aging operations of CD and tape are started at the same time. 5) To exit the aging mode, perform [Cold Reset]. 2. Aging mode in CD section 1) Operation during aging mode In the agining mode ,the program is excuted in the following sequence. (1) The disc tray opens and closes. (2) The disc tray turns to select a disc 3. (3) The pick-up accesses to the first track, and plays 3 seconds. (4) The pick-up accesses to the last track, and plays 3 seconds. (5) The disc tray opens and closes. (6) The disc tray turns to select a disc 1. (7) The same operation starts like step (3). (8) After a disc 1 aging operation, a disc 2 is selected. (9) When an aging operation of a disc 3 is completed, the display AGING value increases. (10) If no error occurs, the aging operation continues repeatedly. 2) Error displayDisc error Display E00D01022 E00D02022 E00D02023 E00D02014 Error Focus error (No disc) Sub Q error (Focus is good) TOC reading error Access error (Unable within regular time) Mechanism error Display E00M__E_0 E00M__C_2 E00M__D_0 E00M__F_3 E00M__D_5 E00M__C_2 E00M__C_3 Error Error during opening tray EX-CHANGE disc error Error during closing tray EX-OPEN error EX-CLOSE error Chuck-up error Unchucking error
