Precautions for Proper Use
●Supply voltage
Make sure that the power is between 6 V and 12 V DC. If the power voltage is too low, abnormal colour
and increased noise may occur. Do not exceed 12 V DC in any case, or the unit could be damaged.
●Allowable ambient temperature and humidity
Be sure to use the unit within the allowable temperature range of 0°C to 40°C and a relative humidity of
30% to 80%. Using the unit at a temperature or humidity outside the allowable ranges could result not
only in malfunction but the impact on the CCD elements could be serious as small white spots may be
generated. When storing the GY-DV300 for a long time, the storage temperatures should be –20°C to
60°C.
●Strong electromagnetic waves or magnetism
Noisemay appear in the picture or audio and/or the colours may be incorrect if thecamera is used near
aradioortelevisiontransmittingantenna,inplaceswhere strong electromagnetic waves are generated
by transformers, motors, etc., or near devices emitting radio waves, such as transceivers or cellular
phones.
●If a transceiver or cellular telephone is used closed to the GY-DV300 while the camera-shake
compensation function is in use, the camera image may flicker due to the influence of emitted
electromagnetic waves.
●Use of wireless microphone near the camera
When a wireless microphone or wireless microphone tuner is used near the camera during recording,
the tuner could pick up noise.
●Avoid using or placing the unit in places;
•subject to extreme heat or cold;
•with excessive dirt or dust;
•with high humidity or moisture;
•subject to smoke or vapour such as near a cooking stove;
•subject to strong vibrations or on an unstable surface.
•also do not leave the unit for long hours in a parked car under direct sunlight or near room heating
equipment.
●Protect the unit from being splashed with water (especially when shooting in the rain).
●Protect the unit from being wet when shooting on a beach.
In addition, salt and sand may adhere to the camera body. Be sure to clean the camera after use.
●Protect the unit against penetration of dust when using it in a place subject to sandy dust.

Routine and Periodical Maintenance
The GY-DV300 incorporates precision mechanical parts, which will collect dirt, wear out and deteriorate
as the unit is used. On the other hand, when the unit has been used for a long period in a normal
environment, the heads, drums and tape transport mechanisms also accumulate dirt that is deposited on
them. Furthermore, dust which penetrates the inside of the VCR section especially during outdoor use
will promote the wear and deterioration of mechanical parts by causing poor contact between tape and
heads or failure to maintain the video and audio quality at high levels. To prevent wear and deterioration,
clean the mechanical parts using a head cleaning tape as routine maintenance. However, as cleaning
with a head cleaning tape alone is not enough for cleaning the entire tape transport mechanism, it is also
recommended to apply periodical maintenance (inspection) to prevent troubles that may be caused by
thesuddenoccurrenceoffailure.Asthereplacement,adjustmentandservicingofpartsrequire advanced
skill and equipment, please consult the person in charge of professional video equipment at your nearest
JVC-authorized service agent.
Head Cleaning
●To maintain beautiful video and sound, be sure
to use a head cleaning tape to clean the head
periodically.(Read “Precautions for Use of Head
Cleaning Tape”on page 10.) If head cleaning is
notperformed periodically,atypeof mosaic noise
called block noise may appear in the picture or
sound may be interrupted.
●Usetheoptionalheadcleaning tape M-DV12CL.
Do not use other than the designated head
cleaning tapes. For instructions on how to use
the head cleaning tape and precautions for its
use,read “Precautions for Use of Head Cleaning
Tape”on page 10.
●When dirt adheres to the video heads of the GY-
DV300, the warning message “HEAD
CLEANING REQUIRED!”appears on the LCD
screen and the viewfinder screen during edit

INTRODUCTION
●Donotset the POWER switch to OFForremovethe power cord during recording orplayback.Otherwise
the tape may be damaged.
●When the unit is not in use, be sure to set the POWER switch to OFF in order to reduce power
consumption.
●Cleaning the camera body: Wipe the body with a dry, soft cloth. When it is extremely dirty, soak the
cloth in a solution of neutral detergent, wring it out and then wipe. To prevent deformation of the body,
etc.andtoavoidoperationhazards,donotallowvolatileliquidssuchasbenzeneand thinner to contact
the body, and do not wipe it with a cloth soaked in such a liquid.
●The camera may be unstable for a few seconds immediately after the power is turned on, but this is not
a malfunction.

TENTATIVE
11
Condensation
●If the unit has been cooled down in a cold place
andisthencarriedtoawarm place, the moisture
containedin the warm air mayadhereto the head
drum or tape guides and be cooled into water
droplets. This phenomenon is referred to as
condensation (dewing). When this occurs, the
head drum and tape guides are covered with
dropletsallowing the tape tostickto them, leading
to tape damage.
●Condensation occurs in the following cases:
•Whentheunitis suddenly
moved from a cold place
to a warm place.
•When a room heater has
just started or when the
unit is exposed directly to
cold air from an air
conditioner.
•When the unit is placed in a very humid place.
Do not leave the videocassette inserted when
movingthecamera under conditions where the
temperature environment changes.
After moving the unit, do not use until the
internal parts have stabilized.
●Whencondensationoccursinthisunit,the“VTR
WARNING (DEW)”appears on the LCD screen
and the viewfinder screen.
To remedy,leavetheunitwiththepowerONand
wait until the WARNING indicator disappears.
●Prevention of condensation
When quickly transporting the GY-DV300 from a
coldto a warmer place, firsttakeoutthe cassette.
Then place the GY-DV300 in a plastic bag and
sealitbeforetransportingthe camera. Leave the
GY-DV300 in the sealed plastic bag until the
camera has the same temperature as the
surroundings. This will prevent condensation.

VTR WARNING (DEW)
Characteristic CCD Phenomena
Smear and Blooming
Duetothe physical structure of a CCD it ispossible
to induce vertical streaking (called “smear”) when
shooting an extremely bright light source.Another
effect is the expansion of light around a bright light
or object (called “blooming”).
The CCD employed in this unit is characterized by
inducing very little smear or blooming.
Nevertheless, please be careful when shooting a
bright light source.
Moire or Aliasing
Shooting stripes or fine patterns may cause a
jagged effect or a banding in fine mesh patterns.
White dots
High temperatures can cause CCD sensor pixels
to malfunction with the effect of white dots in the
image. This condition is conspicuous especially
when gain is applied.
Thisis a characteristicofthe charged-couple device
(CCD). As far as possible, use the unit under
conditions where the temperature of the unit does
not increase.

•The tape counter indication may be irregular
●Please play back a tape that is recorded in the
LP mode on the unit on which the tape was
recorded. Also, these tapes cannot be played
back on digital video units that do not support
the LP mode.
●Videocassettes cannot be used upside down.
Videocassette to be Used
●Avoid storing a videocassette with unevenly
wound tape, as this may damage the tape.
Rewind it to the beginning before placing a
cassette into storage.
●Storevideocassettes in a placewithlittlehumidity
andgoodventilation where mould does not form.
●After a videocassette tape has been used
repeatedly, it becomes unable to maintain full
performance due to an increase in noise caused
by dropouts, etc. Do not continue to use a dirty
