1. INTRODUCTION
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
continue to use a dirty or damaged tape, as this will reduce the rotary head life.

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.
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.

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.

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
