JVC GYHD110U Instructions - Page 7

INTRODUCTION Battery Pack to be Used The GY-HD110 can use any of the following batteries. • BN-V428, BN-V438 Videocassette to be Used • 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. Switch „ 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. Temperature Humidity Hourly temperature change Hourly humidity change Recording 17°C to 25°C 30% to 70% Less than 10°C Less than 10% Storage Short period (Up to 10 years) Long period (Over 10 years) 15°C to 23°C 15°C to 19°C 40% to 55% 25% to 35% H H H H • 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-totape 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, pressure from other tapes can cause distortions and deformations of the tape edges. 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. Head drum Video tape Do not leave the videocassette inserted when moving the camera under conditions where the temperature environment 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. INTRODUCTION 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 that smear or blooming may be induced when shooting a bright light source. Smear Vertical pale streaking appearing at high luminous object Monitor screen High luminous object (Electric light, sunlight, etc.) Blooming Blurring in highlight 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 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. 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 indication may not appear for the first 10-15 minutes after condensation 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 videocassette, 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. 8 9
