Safety Precaution for Repair
1
CAUTION (COLOR LCD)
LCD display; the liquid crystal display (LCD) panel is mode 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 mode 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.
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.
PRODUCT SAFETY NOTICE
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
manufacturer'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.
CAUTION
CAUTION
BLE
VISI
AND INVISIBLE
LASER RADIATION WHEN OPEN.
AVOID EXPOSURE TO BEAM.
CAUTION
There is a high-voltage section inside the DVD video
camera/recorder: When repairing or inspecting it, take
great care to prevent electric shock: Use an isolating
transformer, wear gloves, etc.

them note the following regular indications:
1-2-2 Values in schematic diagrams
The values, dielectric strength (power capacitance) and tolerances of the resistors (excluding
variable resistors) and capacitors are indicated in the schematic diagrams using abbreviations.

1-2-3 Identifications of sides A/B in circuit board diagrams
1) Board having a pattern on one side and parts on both sides.
Side A: Shows discrete parts, viewed from the pattern side.
Side B: Shows leadless parts, viewed from the pattern side.
2) Board having patterns on both sides and parts on both sides.
Side A: Shows parts and patterns which can be seen when the case is opened.
Side B: Shows parts and the pattern on the back of side A.
