CAUTION-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.
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,

2. Information on DVD-RAM Discs
2.1 Comparison of DVD-RAM Discs
The 4.7GB DVD-RAM is standardized as Version 2.0 with respect to the 2.6GB DVD-RAM (Version 1.0), and the major
differences are as follows:
The 8-cm DVD-RAM media is standardized as Version 2.1: It can be used with disc removed from cartridge as well as in
cartridge in the same way as with 12-cm DVD-RAM Type 2.
Notes: 1) In addition to the above, the 4.7GB DVD-RAM has a new defect control system to handle real time recording of
AV data.
2) Among the rewritable DVD standards, only the 4.7GB DVD-RAM is standardized for the 8cm size.
2.2 DVD Video Recording Standard
The DVD video recording standard is a newly established common standard to record video on DVD in real time. The DVD
video standard has already been used for read-only DVD, but it was previously exclusively for playback, so the following
were difficult:
Recording in real time
Addition or deletion of video/audio
Editing
The DVD video standard was reviewed to establish a DVD video recording standard which defines the devices for achieving
the characteristics inherent in disc, starting with the following, in addition to the capabilities of real-time recording and editing
on rewritable DVD media:

cartridge (Type2).
2.4 Available DVD- RAM Discs
There are two types of DVD-RAM disc: for video camera and for PCs. Be sure to use 8 cm DVD-RAM discs (1.4 GB on one
side, 2.8 GB on both sides) noted for video camera use (for AV) with this DVD video camera/recorder.
Most discs for video camera use (for AV) can be removed from their cartridges for recording. Some discs for PC, however,
cannot be removed from their cartridges, and some can be removed but recording cannot be made on them. For details, read
the instruction sheet provided with discs or consult the disc maker.
Examples of discs that cannot be used on this DVD video camera/recorder:
8 cm DVD-RAM discs for PC, CD, DVD-ROM, DVD-Video, MO, MD, iD, floppy disks,etc.

E1 - 4
2.5 Initializing (formatting) DVD- RAM Discs
This DVD video camera/recorder can use only DVD-RAM discs for AV formatted in accordance with the UDF 2.01 file system:
No recording can be made on an unformatted disc.
2.6 Handling DVD- RAM Disc
When the DVD-RAM disc is used for an extended period of time, the temperature will increase because of the heat
inside the DVD video camera/recorder: Be careful when removing the disc.
The DVD-RAM disc is a very delicate recording medium. Leave the disc in the cartridge when using it in this DVD
video camera/recorder.
Do not remove the disc from the cartridge unless needed, and do not open the shutter of cartridge.
Be sure not to touch disc surfaces.
Take great care so as not to scratch or stain disc.
Be careful not to allow the cartridge with disc to fall.
Be careful not to allow condensation.
To store disc cartridge, insert it in plastic case provided.
Do not place the disc cartridge in following places:
Where exposed to direct sunlight for a long time.
Where the humidity is high, or in dusty place.
Where exposed to heat from heater, etc.
Where there may be condensation.
2.7 Removing DVD- RAM Disc from Cartridge

Tip:
The side that will be recorded when SIDE A of disc faces the hand strap is the
opposite side to the "SIDE A" indication.
Cautions:
Most generally available 8 cm DVD- RAM discs can be removed from cartridges
if they are for video cameras; However, before removing disc from cartridge,
read the instruction sheet provided with the disc or consult the disc maker.
Take care with the following when handling the removed disc:
Be sure not to touch disc surfaces.
Be careful not to drop the disc removed from cartridge.
Be sure not to bend the disc.
Do not leave the disc outside the cartridge.
Do not subject the disc to heat.
Do not write on disc with a ball- point pen or pencil.
Be sure not to wipe disc surfaces with thinner,water or anti- static agent.
Use dry, soft cloth to lightly wipe off dust or dirt that adheres to the disc. Never use solvents to clean the disc.
If the disc is removed from cartridge and the data stored by this DVD video camera/recorder is rewritten on devices other
than this DVD video camera/recorder,recording or playback may not be normal,or Disc Navigation may not operate
normally,when the disc replaced in cartridge is used on this DVD video camera/recorder again.
The cartridge protects the surfaces of disc on which high- density recording is possible.Once removed from cartridge, the
disc can be replaced in the cartridge and used with this DVD video camera/recorder, but be sure to observe the
following:
Before replacing the disc in cartridge, make sure that disc surfaces are not scratched,and that no dirt or fingerprint
adheres to them.
Do not record,edit or delete on the disc when scratches, dirt or fingerprints cannot be removed even if disc surface is
cleaned.
When replacing the disc in cartridge, insert it until a click is heard.
Writing similar to recording is be performed even with simple editing or deletion. Make sure that editing or deletion has
been securely performed with the disc removed from cartridge.
Write-protect tabs
The DVD-RAM disc cartridge has write-protect tabs to prevent overwriting
on recorded data. Make sure that the write-protect tab is set to the side
where recording is possible.
Cautions:
Dust, scratches or dirt on the disc surface may cause block noise
because of the principle of disc recording. This does not indicate a fault.
Be careful when handling the disc so that no dirt or fingerprints adheres
to the disc.
This DVD video camera/recorder has a function that allows recording,
avoiding portions of the disc with dust, scratches or dirt [The DVD video
camera/recorder sets to pause ( ) status and automatically restarts
recording ( REC )] .
This will interrupt recording for several seconds to several minutes, and
multiple thumbnails will be created in one recording as shown in the
figure. In this case, the recordable time will decrease.

4. Explanation of Trouble Messages
A message may appear while you are operating the DVD video camera/recorder. If a message appears, refer to the following
table and take appropriate corrective action.

E1 - 10
Message
Cannot remove scenes
Cannot delete scenes
Please update disc
Disc id full

Error on disc
All data will be deleted
Continue?
Cause
This may occur when
scene that was edited for
division, etc. is to be
unload.
This may occur when
scene that was edited for
division, etc. is to be
deleted.
The thumbnail at the start
of program or play list may
not appear when disc
edited on device other
than this DVD video
camera/recorder is used,
or, when editing, such as
combining, is performed on
this DVD video camera/
recorder.
The number of entered
scenes has reached the
limit that can be entered,
so the control information
for generating thumbnails
cannot be added.
Has the disc been initial-
ized on a PC?
Has initializing the disc on
a PC been interrupted?
Troubleshooting
Combine the divided scenes,
and then unload them.
Combine the divided scenes,
and then delete them.
If thumbnail is information is
insufficient, Disc Navigation
will automatically create
thumbnails after it starts.
Combine several scenes or
delete (unload) them.
Choose "Yes" and initialize the
disc when using it on this DVD
video camera/recorder.
Technical explanation
This appears if CELL is to be
divided (increased) when the
number of CELLs has reached
the limit of 999. (If recording
continues without editing on
this DVD video camera/
recorder, 1 scene will make up
1 EP or 1 CELL. If scenes are
combined, the number of EPs
will decrease, but the number
of CELLs will not decrease. If
CELL is to be divided at the
upper limit number of CELLs,
several scenes must be
deleted in this status without
traversing multiple CELLs. (*2)
Same as above.
This appears if a disc in which
EP is not attached to the
beginning of program or play
list is inserted (this occurs
when EP was not attached to
the beginning of program or
play list when editing was
performed on devices other
than this DVD video camera/
recorder, or scenes traversing
multiple programs were
combined, and thumbnails
cannot be displayed on Disc
Navigation screen). This
message appears when Disc
Navigation is started first after
power is supplied: Operation
following message instructions
will attach EP to the beginning
of program or play list, thereby
enabling thumbnails to be
displayed.
This appears if the number of
scenes has reached 999 when
control information is being
updated. (*1)
This appears if the disc has a
file that has been recorded in
a format that cannot be
detected by UDF2.0. (This
problem will be solved if the
disc is formatted on this DVD
video camera/recorder.)
This appears if the disc has
logically been destroyed. (The
problem frequently occurs
because of problem in the
UDF file system.) Although the
disc for which this message
appeared cannot be used as
is, it may be usable after it is
initialized (Note, however, that
all recorded data will be
deleted).

occurred during editing of
scenes.
-----
The temperature inside the
DVD video camera/
recorder is too high, and
reading or writing of the
data on disc may not be
performed normally.
It is possible that the
system cannot normally
complete writing of file
when power is turned off
for some reason during
recording or editing
(deleting, dividing or
combining scenes, or
creating play list). Selecting
"Yes" will automatically
repair the video file, but
even if "No" is selected,
the same message will
appear when the DVD
video camera/recorder is
turned on next time. (Do
not remove the disc while
the DVD video camera/
recorder is recognizing it:
lqnoring this will deactivate
the file repair function.)
Troubleshooting
Remove the disc and wipe off
fingerprints, dust, etc. before
reusing it, or use another disc.
Turn off the DVD video
camera/recorder with the disc
being used in it, connect AC
adapter/charger, and then
power the DVD video camera/
recorder again. Scenes will be
repaired.
Delete unnecessary scenes
before using this disc, or use
another disc.
Turn the DVD video camera/
recorder off and wait for a
while. The temperature will be
effectively decreased if the
DVD video camera/recorder is
placed in a well-ventilated
spot.
Follow the instructions on
screen, taking note of the
following cautions:
Data may not be repaired,
depending on the timing
when power was turned off.
Data may not be repaired
normally if data recorded on
another recorder is mixed in.
The repaired data may be
different from the original
recorded content because of
partial deletion of defective
portion.
Since the date/time for repair
is added to the repaired data
(only the corrected portion
for partial repair), the original
date/time information will be
lost.
Since all movies, and then all
stills, are repaired, the order
of recorded contents will be
lost.
(In case of message (3) only)
Technical explanation
This appears if formatting of
disc could not be normally
performed (writing could not
be done to specified address).
This appears if power is shut
off for some reason during
movie recording. This DVD
video camera/recorder has a
function that automatically
saves files if power is shut off
during movie recording: This
function will repair some files
when the DVD video camera/
recorder is restarted (it may
take 10-20 minutes to repair
files). The DVD video camera/
recorder must be stably
powered using AC adapter for
restart.
This may appear if some
operation, such as adding
thumbnails, etc., is attempted
when the recordable area on
disc has been nearly used up.
This appears if recording,
playback, etc. is performed in
an environment near the limit
of allowable operating tem-
perature (humidity) for an
extended time. This message
will not appear in ordinary
situations of use, and reliability
of recorded data will decrease
in a situation where this
message appears.
This DVD video camera/
recorder has a function that

Technical explanation
This DVD video camera/
recorder has a function that
automatically saves files if
power is shut off during movie
recording: This function will
repair some files when the
DVD video camera/recorder is

10-20 minutes for file repair
work, the DVD video camera/
recorder must be stably
powered using AC adapter:
The message will appear at
this time. Note that if power is
again shut off while files are
being repaired, restoration of
those files being repaired will
no longer be possible.
This message appears if there
is a problem in the disc or in
this DVD video camera/

*1: The number of recordable scenes on this DVD video camera/recorder is 999: Since the maximum number of EPs (record
ing points) defined by the RTR standard (DVD-RAM recording standard) is 999, and 1 EP is allocated to 1 scene, this
limitation exists.
*2: The number of recordable CELLs (minimum recording unit) on this DVD video camera/recorder is 999. This limitation
exists because the maximum number of CELLs defined by the RTR standard (DVD-RAM recording standard) is 999.
