NOTES ON HANDLING THE OPTICAL
The laser diode in the optical
During repair, pay attention to electrostatic
The flexible board is easily damaged and should be handled with care.
NOTES ON LASER DIODE EMISSION CHECK
Never look into the laser diode emission from right avove when checking it for adustment. It is feared that you will lose your sight.
NOTES ON HANDLING THE OPTICAL

OPTICAL PICK-UP FLEXIBLE BOARD
Notes on chip component replacement
•Never reuse a disconnected chip component.
•Notice that the minus side of a tantalum capacitor may be dam- aged by heat.
Flexible Circuit Board Repairing
•Keep the temperature of the soldering iron around 270 ˚C dur- ing 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.
CAUTION
Use of controls or adjustments or performance of procedures other than those specified herein may result in hazardous ra- diation exposure.
