CAUTION
Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous ra­diation exposure.
This appliance is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT MARKING is located on the rear exterior.
CAUTION
The use of optical instruments with this product will increase eye hazard. As the laser beam used in this CD/DVD Player is harmful to eyes, do not attempt to disassemble the cabinet. Refer servicing to qualified personnel only.
The following caution label is located inside the apparatus.
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 pick-up block. Therefore, when checking the laser diode emis­sion, observe from more than 30 cm away from the objective lens.
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 the soldering iron around 270 ˚C 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.
NOTES ON MB BOARD EXCHANGE
If a MB board is exchanged, “DRIVE AUTO ADJUSTMENT’’ may be unable to be performed. In this case, initialize a memory in the following procedure.
1. Starting Test Mode (See page 11).
2. Press the 2 button of remote commander to set the Drive
Manual Operation (See page 18).

Data write read, and accord check Error 09: ARP ←→ RAM data bus error Data 0x0001 to 0x8000 where one bit each is set to 1 are written to the address 0 of RAM (IC303) connected to the ARP (IC302) through the bus, then they are read and checked. In case of discord, written bit pattern and read data are displayed. If data where multiple bits are 1 are read, the bits concerned may touch each other. Further, if data where certain bit is always 1 or 0 regardless of written data, the line could be disconnected or shorted.
(5-4) ARP to RAM Address Bus
Data write other address read discord check Error 10: ARP RAM address bus error Caution: Address and data display in case of an error is
different from the display of other diagnosis (de-
scribed later). Before starting the test, all addresses of RAM (IC303) are cleared to 0x0000. First, 0xA55A is written to the address 0x00000, and the address data are read and checked from addresses 0x00001 to 0x80000 while shifting 1 bit each. Next, the data at that address is cleared, and it is written to the address 0x00001, and read and checked in the same manner. This check is repeated up to the address 0x80000 while shifting the ad­dress data by 1 bit each. If data other than 0 is read at the addresses except written address, an error is given because all addresses were al­ready cleared to 0. In this check, the error display pattern is different from that of other diagnosis; read data, written address, and read address are displayed in this order. How­ever, the message uses same template, and accordingly ex­change Address and Data when reading. The following dis­play, for example,

So, before clearing, make a note of the adjusted data. For reference, the drive has been designed so that the gain center value is 20 and offset value is 80. Other values will be in a range of 10 to 80. If extreme value such as 00 or FF is set, adjustment will be faulty. In such a case, check for disc scratch or cable dis­connection, then perform adjustment again.
