The GY-DV500 can use any of the following battery packs.
●
Flat shape type
●
Anton-Bauer battery pack: Trimpack 13/14 Series
Magnum 13/14 Series
Compack 13/14 Series
Propack 13/14 Series
* 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
37.
●
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 condensation occurs in this unit, the DEW indicator
on the display lights up, and the WARNING LED blinks red.
(See page 86)
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.
• When the unit is suddenly
moved from a cold place to a
warm place.
• When a room heater has just
star ted or when the unit is
exposed directly to cold air from
an air conditioner.
• When the unit is placed in a very
humid place.
1-5 Battery Pack to be Used
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 69)
1-6 Condensation
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.
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.
