This appliance is classified as a CLASS 1 LASER product. The CLASS 1 LASER PRODUCT MARKING is located on the rear exterior.
CAUTION
Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous radiation exposure.
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 chip component replacement
•Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam­aged by heat.
On AC power adaptor
Use only the commercially-available AC power a output is 4.5 V DC, 500 mA. Do not use any oth It may cause a malfunction.

SERVICING NOTE

XP-ER800/ER800N/ER800R
NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic breakdown because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body. During repair, pay attention to electrostatic breakdown 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.
BEFORE REPLACING THE OPTICAL PICK-UP BLOCK
Please be sure to check thoroughly the parameters as par the “Optical Pick-Up Block Checking Procedures” (Part No.: 9-960-027-11) issued separately before replacing the optical pick-up block.
LASER DIODE AND FOCUS SEARCH OPERATION CHECK
During normal operation of the equipment, emission of the laser diode is prohibited unless the upper lid is closed while turning ON the S302. (push switch type) The following checking method for the laser diode is operable.
• Method: Emission of the laser diode is visually checked.
1. Open the upper lid.
2. With a disc not set, turn on the S302 with a screwdr iver ha ving a
thin tip as shown in Fig.1.
3. Press the u button.
4. Observing the objective lens, check that the laser diode emits
light. When the laser diode does not emit light, automatic power control circuit or optical pickup is faulty. In this operation, the objective lens will move up and down 4 times along with inward motion for the focus search.
