LCD display; the liquid crystal display (LCD) panel is made by highly precise technology.
More than 99.99% of its picture elements (pixels) are effective, but some (less than 0.01%) may appear as colored
bright dots. This does not indicate a fault as the LCD panel stretches the limits of current technology.
CLASS 1
LASER PROCTECT
CAUTION
This product contains a laser diode of
higher class than 1. To ensure contin-
ued safety, do not remove any covers
or attempt to gain access to the in-
side of the product. Refer all servicing
to qualified personnel.

ANA and DIG circuit board diagrams included are for reference during troubleshooting.
This manual does not include the schematic diagrams of ANA and DIG circuit boards, since these boards must be
replaced in units of board and their components are not assigned as service parts.
SHD, RAM2LD and PHD circuit board diagrams included are for reference during troubleshooting.
This manual does not include the schematic diagrams of SHD, RAM2LD and PHD circuit boards, since these
boards are included in the mechanism unit and they or their components are not assigned as service parts.
Many electrical and mechanical parts have special safety-related characteristics. These are often not evident from visual
inspection nor can the protection afforded by them necessarily be obtained by using replacement components rated for a
higher voltage, wattage, etc. Replacement parts which have these special safety characteristics are identified in this
Service Manual. Electrical components having such features are identified by marking with a
on the schematics and
the parts list in this Service Manual. The use of a substitute replacement component which does not have the same safety
characteristics as the HITACHI recommended replacement one, shown in the parts list in this Service Manual, may create
shock, fire, or other hazards. Product safety is continuously under review and new instructions are issued from time to time.
For the latest information, always consult the current HITACHI Service Manual. A subscription to, or additional copies for,
HITACHI Service Manual may be obtained at a nominal charge from HITACHI SALES CORPORATION.

Lithium battery; danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type
recommended by the equipment manufacturer. Discard used batteries according to manufacuturer's instructions.
When replacing the lithium battery it is important to use the same type and connect it correctly.
WARNING:
Lithium batteries contain dangerous chemicals.
Handle and dispose of with great care.
Do not throw in a fire.
Do not short circuit it.
For disposal place in a plastic bag and put in waste bin.
