The LED mounted to each side of the front panel of this set is very sensitive to static electricity. When handling the LED base
plate, be very careful about it.
∙
∙∙∙
Do not replace a blue LED singly. If replaced singly, it may be subject to electrostatic breakdown or deterioration in quality.
When replacing the LED base plate, be sure to replace L and R sides simultaneously to permit the brightness adjustment.
*For configuration at the time of supply of replacement parts,refer to “Printed Circuit Board Diagram.”
