Condensation
Head cleaning
•Recording or playing back with a dirty head will result in block noise or disrupted sound. Perform regular head cleaning to maintain superior image and sound quality.
Block Noise
•For information on how to use the head cleaning tape and the relevant remarks, refer to Xpage 9, “Cleaning tape”.
•If the head is dusty, “HEAD CLEANING REQUIRED!” will be displayed on the moni- tor when this unit plays a tape.
HEAD CLEANING REQUIRED!
•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, which are not warmed enough. When chilled, the vapor turns into droplets of water. This state is known as condensation. When condensation occurs, the videotape adheres to the head drum or the tape guides and will be damaged.
•Condensation occurs on this unit in the fol- lowing circumstances:

When a cassette tape is loaded, do not transport e.g., from a cold outdoor place to a warm room thus subjecting the unit to drastic temperature changes. After moving the unit, do not use it until the inner mechanism stabilizes.
•When condensation occurs, the monitor displays the following warning:
