For recording and storing videotapes in the best con- dition

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

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

Storage

Condensation

•If this device 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 (dew). When this occurs, the head drum and tape guides are covered with droplets allowing the tape to be stuck to them, leading to tape dam- age.

Characteristic CCD Phe- nomena

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 device is characterized by induc- ing very little smear or blooming. Nevertheless, please take note that smear or blooming may be induced when shooting

CAUTION

Use only the recommended batteries.

If a heavy battery is used, the battery may fall out depend- ing on the way the HD camera recorder is used.

• Do not leave the videotapes neglected for a long period. If

•Condensation occurs in the following cases:

•When this device is suddenly moved from a cold place to a warm place.

•When a room heater has just

started or when this device is exposed directly to cold air from an air conditioner.

•When this device is placed in a very humid place.

Moire or Aliasing

•Use JVC’s videocassette tapes marked with the A symbol.

• 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.

•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.

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 this device, 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 device.

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-

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 con- spicuous especially when gain is applied.

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

Switch

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 this device from one place to another where

the temperatures are greatly deferent, first remove the vid-

eocassette, place this device in a tightly sealed vinyl bag,

and then move it to a new environment.

To ensure no condensation occurs, allow the temperature

of this device in the bag to reach that of the new environ-

ment before using it.
