PRODUCT SAFETY NOTICE

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.

!

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.

CAUTION (CRT EVF)

Be careful of the section painted in white on the electronic viewfinder circuit board as it generates a high voltage.

X-RAY RADIATION

The primary source of X-ray radiation in this viewfinder is the picture tube. The tube used in this viewfinder is specially
constructed to limit X-ray radiation emission. For continued X-ray radiation protection, the replacement tube must be
same type as the original, Hitachi approved one.

How to discriminate the "TYPE" identifications in the manual

The parts and circuits are identified by "TYPE" in this manual to discriminate the differences between models. The
TYPE numbers are the same as the model numbers. The table below shows how to read the type identifications.

TYPE identification Model name

TYPE 675 VM-H675LA
TYPE 575 VM-E575LA

Notes on the Battery

It is recommended that the battery always be left
in the discharged state when not in use, and
charged before you use it.
Avoid storing a fully charged battery, and do not
store it in a place where the temperature is high:
this will damage the battery.
Do not operate the battery at temperature below
14 F (– 10 C) or above 113 F (45 C). At extremely
low temperatures operation time decreases, while
at high temperature the battery may be dam­aged.
Do not attach a hot battery to the camcorder.
Allow it to cool.

THERE ARE NO USER-SERVICEABLE PARTS

INSIDE THE BATTERY

OR AC ADAPTOR.

THROWING THE BATTERY INTO FIRE

OR EXPOSING IT TO EXCESSIVE HEAT

(ABOVE 140 F [60 C])

MAY CAUSE INJURY.

SHORTING THE BATTERY’S TERMINAL

INCREASES RISK OF FIRE OR

ELECTRICAL SHOCK.

Removing the Battery Pack

Slide the BATT. EJECT lever in the direction of the
arrow and hold it; then slide the battery to the
upper side and remove.

Reference of Charged Level

Charg ing the Battery

The first step is to set the battery for charging. To charge the battery, attach it to the camcorder, and
connect the VM-ACE5A AC adaptor. Charge the battery at a temperature range of 50 F (10 C) – 86 F
(30 C) to prevent damage to the battery.

Note: This camcorder operates with a lithium ion battery such as VM-BPL13/VM-BPL30/VM-BPL60.
Note: We cannot be responsible for any malfunctions of the camcorder which occur when you use bat-

tery packs other than those specified.

BATT. CHARGE Indicator

Charge the battery on a flat surface this is free of
vibration.

Make sure the CAM/OFF/VIDEO switch is set

1

to OFF position.

CAM/OFF/VIDEO Switch

Attach the battery pack to the camcorder.

2

Place the battery on the guide platform and
slide it down so that it fits into the camcorder.

Note: Always attach a battery only by the pro­cedure described here. Attaching a battery
forcibly could damage it.

Plug the AC adaptor power cord into an AC

3

outlet.
Make sure that the wide blade fits into the wide
slot. If it doesn’t fit, try reversing it. If the
blades still do not fit fully into the outlet, either
contact an electrician to replace your obsolete
outlet, or use a polarized cord or outlet access­ory.
Connect the AC adaptor DC plug to the DC IN

4

jack of the camcorder.
Charging will start within five seconds. During
charging, the BATT. CHARGE indicator of the
camcorder will flash or light to give you a refe -

To DC IN Jack

rence of the charged level.

Note: If the BATT. CHARGE indicator flashes
once every two seconds, the battery could be
defective.

Note: The BATT. CHARGE indicator will not light
at all when the AC adaptor is defective.

Note: You can use the battery before it is com ­pletely charged.

Note: When charging is complete, the BATT.
CHARGE indicator on the camcorder will light.
IF the fully charged battery is removed and
then reattached, the camcorder will again
enter the charge mode, and the BATT.
CHARGE indicator will flash. It will take a few
minutes for the camcorder to enter the charge
complete status.

Note: Charging at low temperatures will
decrease charge capacity.

After charging is complete, disconnect the AC

5

adaptor DC plug from the camcorder.
Disconnect the AC plug from the AC outlet.

6

Detach the battery from the camcorder.

7

Note: Always remove the battery from the

camcorder after use.
Note: Charging will not be performed when

the CAM/OFF/VIDEO switch of the camcorder
is set to CAM or VIDEO. However, if recording
pause continues for more than 5 minutes in the
CAM mode, the camcorder will automatically
turn off, after which charging will start. If the
sub-power switch is set to LOCK, charging will
be performed even when the CAM/OFF/VIDEO
switch is set to CAM.

Note: If the DC plug is disconnected when the
battery is attached and the CAM/OFF/VIDEO
switch is set to CAM or VIDEO, the camcorder
will turn off once, but then automatically turn
on again. Note that the battery will discharge
if the camcorder is left as is.

General Maintenance

Cleaning the Camcorder Heads

Dirt can accumulate on the video heads on the
camcorder causing the playback picture to become
blurred or appear as if video information is lost.
This often means that the video heads are dirty.
Use a video head cleaner such as a dry type head
cleaning tape to clean the heads.

If after cleaning the heads the picture does not clear
up consult your nearest dealer or VCR service
center for professional head cleaning.

Cleaning the Lens and Picture Tube of the Electronic
Viewfinder

The lens of the electronic viewfinder can be user-cleaned if dust, dirt, or other foreign matter adheres
to it.
