The back light (fluorescent tube) is driven by a high volt-
age AC power supply. Therefore, do not touch the back
light holder to avoid electrical shock.

When replacing the LCD unit, be careful to prevent dam-
ages caused by static electricity.

Set the LCD BRIGHT (Menu setting) to the center.
Set the LCD B.L. (Menu setting) to the BRT NORMAL.
Set the LCD COLOR (Menu setting) to the center.

Most of the measuring points for adjusting the LCD display are
concentrated in the following connector.
