JVC GY-HD100, GY-HD101 manual Battery Pack to be Used, Videocassette to be Used, Condensation

INTRODUCTION

INTRODUCTION

Battery Pack to be Used

The GY-HD100 can use any of the following batteries.

• BN-V428, BN-V438

Videocassette to be Used

• Use JVC’s videocassette tapes marked with the A sym-

„For recording and storing videotapes in

the best condition

Observe the following instructions for the best recording and storage of videotapes.

•Take care of the conditions of handling videotapes. It is rec- ommended that you record and store videotapes in the environment below.

Storage

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.

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 take note

bol.

• Mini DV videocassette : M-DV63HD M-DV63PROHD

* Do not use M-DV80.

• Videocassettes cannot be used upside down.

• Avoid storing a videocassette with its tape not being com-

pletely wound, 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.

•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 con- ditioner.

•When the unit is placed in a very humid place.

•	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 or damaged tape, as this will reduce the
	rotary head life.
•	Videocassette tapes with the A symbol are provided
	with a switch on the back to prevent 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.

•Do not leave the videotapes neglected for a long period. If videotapes are left wound for a long period of time, it may result in distortion of the tape. Also it may cause tape-to- tape adhesion (known as blocking). It is recommended that videotapes be unspooled and rewound once a year for refreshing.

•When tapes are not in use, store them in cases and on end. Storage cases protect videotapes from humidity, dust and ultraviolet light. Keep tapes in cases and do not store them lying flat. When housed in a horizontal position, pres- sure from other tapes can cause distortions and deforma- tions of the tape edges.

Do not leave the videocassette inserted when moving the camera under conditions where the temperature environ- ment changes.

After moving the unit, do not use until the internal parts have stabilized.

•“CONDENSATION ON DRUM” is displayed on the LCD monitor and in the viewfinder when condensation occurs in this unit.

Keep the power on until the warning message disappears.

•Pay attention to condensation even before the condensa- tion indication appears.

As condensation forms gradually, the condensation indica- tion may not appear for the first 10-15 minutes after con- densation 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.

•To prevent condensation

When moving the unit from one place to another where the temperatures are greatly deferent, first remove the video- cassette, place the unit in a tightly sealed vinyl bag, and then move it to a new environment.

To ensure no condensation occurs, allow the temperature of the unit in the bag to reach that of the new environment before using it.

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 produce the effect of white dots in the image. This condition is conspic- uous 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.
