Cautions for Use
(Continued)
∫ Condensation
Determining Whether Condensation Has
Formed Inside and Remedy for Condensation
If the Condensation Indication flashes after you
turn on the Movie Camera, condensation has
formed inside the Movie Camera. In this case, the
Movie Camera automatically switches off after
approximately 1 minute.
Remedy as follows:
1
Take out the cassette.
All other functions do not work. Depending on
the amount of condensation, it may not be
possible to take out the cassette. In this case,
wait 2–3 hours before taking out the cassette.
2
Leave the Cassette Compartment open and
wait for 2–3 hours.
The required time depends on the amount of
condensation and the ambient temperature.
3
After 2–3 hours, turn the Movie Camera on
and check if the Condensation Indication
is displayed.
Even if the Condensation Indication is no
longer displayed, wait 1 more hour for added
safety before using the Movie Camera again.
Pay Attention to Condensation Even Before the
Condensation Indication Appears.
≥As condensation forms gradually, the
Condensation Indication may not appear for the
first 10–15 minutes after condensation has
formed inside.
≥In an extremely cold place, the condensation
could freeze and turn into frost. In such a case, it
takes an additional 2–3 hours for the frost to first
melt into condensation and then to be dissolved.
Remedy for a Fogged-up Lens
Set the [OFF/ON/MODE] Switch to [OFF] and
leave the Movie Camera in this condition for about
1 hour. When the lens has reached about the
same temperature as its surroundings, it
automatically clears up.
Periodic Inspection
To ensure optimum picture quality, it is
recommended that you have worn-out parts such
as video heads replaced after approximately
1000 hours of use. (However, this depends
considerably on the conditions of use such as
temperature, humidity and dust.)
∫ Optimum Use of the Battery
Special Characteristics of the Battery
This Battery is a rechargeable lithium-ion battery.
Its ability to generate electric energy is based on
an internal chemical reaction. This reaction is
easily influenced by ambient temperature and
humidity, and the useful operation time that the
Battery can provide becomes shorter at high and
low temperatures. When used in extremely cold
surroundings, the Battery may only be able to
provide approximately 5 minutes of operation time.
If the Battery becomes extremely hot, a protection
function is activated and prevents the use of the
Battery for some time.
110
After Use, Always Remove the Battery.
Be sure to remove the Battery from the Movie
Camera. (If it is attached to the Movie Camera, a
small amount of electric current is consumed even
if the Movie Camera is turned off.) Leaving the
Battery attached to the Movie Camera for a very
long time could cause it to become excessively
discharged, so that it cannot be used any more
even after charging.
Keep the Battery's Terminals Clean.
Be careful that the terminals do not get plugged up
with dust, dirt or other substances.
If you accidentally drop the Battery, confirm that
the Battery itself and the terminals are not
deformed. Attaching a deformed Battery to the
Movie Camera or to the AC Adaptor could damage
the Movie Camera or the AC Adaptor.
Discarding a Battery That Has Become
Unusable
≥The usable life of the Battery is limited.
≥Do not throw the Battery in a fire because it could
explode.
∫ Precautions for Storage
Before Storing the Movie Camera, Take out the
Cassette and Remove the Battery.
Store all equipment in a dry place where the
temperature remains relatively constant.
(Recommended temperature is 15oC–25oC and
recommended relative humidity is 40%–60%.)
Movie Camera
≥Wrap it with a soft cloth to prevent dust from
entering.
≥Never leave the Movie Camera in places with
high temperature.
Battery
≥Extremely low or high temperature shortens the
Battery life.
≥Storing it in places with oily smoke and a lot of
dust could cause the terminals to get rusty, and
this can result in malfunction.
≥Do not allow metal objects (such as
necklaces and hair pins) to touch the battery
terminals. Short-circuiting may occur and
generate heat, and touching it in this
condition could inflict serious burns.
≥Store the Battery in discharged condition. If you
store the Battery for a long time, it is
recommended that you charge it once a year and
completely use up the charge before storing it
again in discharged condition.
Cassette
≥Rewind the tape to its beginning before storing.
Leaving the cassette with the tape stopped
halfway for more than 6 months (depending on
the storing condition) loosens the tape. Be sure
to rewind it to the beginning.
≥Put the cassette in its case to store it.
Dust, direct sunlight (ultraviolet rays) and
humidity could damage the tape. Dust contains
hard mineral particles and cassettes with dust
damage the video heads and other parts of the
Movie Camera. Make it a habit to always put the
cassette back into its case.
≥Completely wind the tape forward and then
rewind it once every half year. Leaving the
cassette for more than a year without winding/
rewinding it may deform the cassette because of
stretching and shrinking of the tape due to
changes in temperature and humidity. Also, the
tape may stick together.
≥Do not place the cassette near strongly
magnetized objects or equipment.
≥The tape surface is coated with microscopic
magnetic particles and they record signals. Such
objects as magnetic necklaces and toys have
stronger magnetic force than commonly thought,
and this could erase the recorded contents and
cause noise in picture and sound.
MultiMediaCard/SD Memory Card
≥While the Card is being read, do not remove it,
turn off the power, or subject it to vibrations and
shocks.
≥Do not leave the Card in a place with high
temperature, exposed to direct sunlight, or where
electromagnetic waves and static electricity can
be generated.
≥Do not bend or drop the Card as this could
damage the Card or the stored contents.
≥After use, be sure to remove the Card from
the Movie Camera.
≥After using the Card or when storing or carrying
it, put it in the supplied Card Case.
≥Do not touch the connector on the rear edge of
the Card with your fingers and take care that no
dirt, dust or water enters it.
∫ Other Useful Information
LCD Monitor
≥In places where big changes in temperature
occur, condensation may form on the LCD
Monitor. Wipe it with a soft, dry cloth.
≥If the Movie Camera is very cold when it is turned
on, the picture on the LCD Monitor is initially a
little darker than normally. However, as the
internal temperature rises, the LCD Monitor
regains its normal brightness.
Extremely high precision technology is
employed to produce the LCD Monitor screen
featuring a total of approximately 200,000
pixels. The result is more than 99.99% effective
pixels with a mere 0.01% of the pixels inactive
or always lit. However, this is not a malfunction
and does not affect the recorded picture.
Viewfinder
≥Do not leave the Viewfinder or the Lens aimed at
the sun. This could seriously damage internal
parts.
≥If you use a large-capacity Battery (CGP-D320;
optional) attached to the Movie Camera, viewing
the picture in the Viewfinder from behind may not
be practical. In this case, turn up the Viewfinder
to an angle that allows comfortable viewing.
Extremely high precision technology is
employed to produce the Viewfinder screen
featuring a total of approximately 180,000
pixels. The result is more than 99.99% active
pixels with a mere 0.01% of the pixels inactive
or always lit. However, this is not a malfunction
and does not affect the recorded picture.
Lens Hood
≥When attaching the Filter Kit (VW-LF43WE,
optional), attach it on the inside of the Lens Hood
without removing the Lens Hood.
≥When you want to attach the Tele Conversion
Lens (VW-LT4314ME, optional) or the Wide
Conversion Lens (VW-LW4307ME, optional), be
sure to first remove the Lens Hood by turning it
counterclockwise.
≥During recording with a filter or conversions lens
attached, the four corners of the picture may
become dark (vignetting effect), when you push
the [W/T] Zoom Lever toward [W]. For details,
please also read the operating instructions of the
accessory being used.
Microphone Socket
≥If you want to perform audio dubbing via an
external microphone or audio equipment,
connect it to the [MIC] Socket. In this case, the
Movie Camera's built-in microphone is turned off.
Video Flash
When using a Video Flash, setting [RED EYE
REDUCTION] on the [OTHER FUNCTIONS] Sub-
Menu to [ON] can help reduce the "red eye"
phenomenon in your pictures.
≥When setting [RED EYE REDUCTION] to [ON],
the [£] Indication is displayed.
≥The [ß] Indication is flashing, when the Video
Flash is charging. When it is displayed, the flash
can be fired.
≥The available range of the Video Flash is
approximately 1 to 4 metres in a dark place.
Pictures will appear dark when they are recorded
using the Video Flash at distances greater than
4 metres.
≥When the Power Switch on the Video Flash is set
to the Auto position and the Movie Camera's iris
is adjusted, the [ß] Indication may disappear and
the Video Flash may not fire.
≥The shutter speed and iris value are fixed when
the Video Flash is used.
≥Using the Video Flash outdoors or with backlight
or other bright conditions may result in white
blotches (colour blotches) on the pictures.
≥Under backlight conditions, either adjust the iris
manually or use the Backlight Compensation
Function.
