1-5 Videocassette to be Used

● Use JVC's videocassette tapes marked with MiniDV for
this unit.
Please use DVM60 or DVM30 type videocassettes.
● Videocassettes cannot be used upside down.
● 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.
● Store videocassettes in a place with little humidity and good
ventilation 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

1-6 Battery Pack to be Used

The GY-DV550 can use any of the following battery packs.
● Flat shape type
● Anton-Bauer battery pack: Trimpack 13/14 Series
To display the remaining battery power accurately, set the
VCR Setup Menu item No. 396 BATTERY TYPE according
to the type of the battery pack in use. (See page 75)

1-7 Condensation

● If the unit has been cooled down in a cold place and is then
carried to a warm place, the moisture contained in the warm
air may adhere to 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 droplets allowing the tape
to be stuck to them, leading to tape damage.
● Condensation occurs in the following cases:
• When the unit is 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.

1-8 Characteristic CCD Phenomena

Smear and Blooming
Due to the physical structure of a CCD it is possible 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.

continue to use a dirty or damaged tape, as this will
reduce the rotary head life.
● Videocassette tapes marked
MiniDV are provided with a
switch on the back for use in
preventing accidental
erasure.
● Slide the switch to SAVE to
protect the required recording
in the tape from being
overwritten.
● To record on the tape, slide the
switch to REC.
* An Anton-Bauer battery pack cannot be connected directly
to the camera. It is necessary to mount the optional battery
holder.
● Battery holder: Anton-Bauer QRQ27
For details on how to mount the battery holder, see page
39.
Do not leave the videocassette inserted when moving the camera
under conditions where the temperature environment changes.
● When condensation occurs in this unit, the DEW indicator on the
display lights up, and the WARNING LED blinks red. (See page 96)
To remedy, leave the unit with the power ON and wait until
the WARNING LED stops blinking red and the DEW indicator
disappears from the counter display.

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.
This is a characteristic of the charged-coupled device (CCD).
As far as possible, use the unit under conditions where the
temperature of the unit does not increase.
