Precautions on the use of tape ● Reverse sides of videotapes cannot be used. ● Please store the tape only after it has been fully rewound, so as to avoid damaging the tape. ● Please store the cassette in places low in humidity, well-ventilated and fungus-proof. ● When a cassette is used repeatedly, noise may increase due to e.g., dropout, etc. hence affecting its performance. Please do not use dirty or damaged tapes as they will shorten the life span of the rotation head. 8 Condensation ● When this unit is moved from a cold to a warm place abruptly, the vapor in the warm air will come into contact with the head drum or the tape guides. When chilled, the vapor turns into droplets of water. This state is known as condensation. When condensation occurs, the videotape will adhere to the head drum or the tape guides and will be damaged. ● When condensation occurs, the monitor displays the following warning: CONDENSATION ON DRUM ● Condensation occurs on this unit in the following circumstances: • It is moved abruptly from a cold place to a warm place. • It is used in a room immediately after the heater has been turned on, or when cold breeze from an air-conditioner blows onto it. • It is used at a place of high humidity. Head drum Videotape To remedy, leave the unit with the power ON and wait until the WARNING indicator disappears. ● Prevention of condensation When transporting the BR-DV3000 from a cold to a warmer place abruptly, first take out the cassette. Then place the BR-DV3000 in a plastic bag and seal it before transporting the camera. Leave the BR-DV3000 in the sealed plastic bag until the camera has the same temperature as the surroundings. This will prevent condensation. When a cassette tape is loaded, please do not transport e.g., from an external cold place to a warm room thereby subjecting the unit to drastic temperature changes. After moving the unit, please do not use it until the innards are stabilized. 9
