0 The blue LED mounted to each sides of front panel is very
sensitive to static electricity. When handling the LED base
plate, be very careful about it.

- Do not replace the blue LED by itself because it may be
subject to electrostatic breakdown or deterioration in
quality. When replacing the LED base plate, be sure to
replace L and Ft sides simultaneously to adjust the
brightness. For configuration at the time of supply of
replacement parts, refer to Printed Circuit Board Diagram.
