Dew Formation

•What is “dew formation”?

When cold water is poured into a glass, dew drops form on the glass. This clinging of water drops is called dew formation.

•When dew forms in your VIEWCAM.

Dew will gradually form on the head drum of your VIEWCAM and make the video tape stick to the head. This causes damage both to the head and the tape. When dew formation occurs, recording and playback may not function properly.

Dew is likely to form in the following circum- stances:

•When moving the VIEWCAM from a cold place to a warm place.

•When placing the VIEWCAM in a cold room which is then heated rapidly.

•When moving the VIEWCAM outdoors from an air conditioned room.

• When placing the VIEWCAM in the direct path of air blowing from an air conditioner.

• When placing the VIEWCAM in a humid room.

•How to prevent trouble due to dew formation.

When using the VIEWCAM in a place where dew formation is likely to occur, allow the VIEWCAM and the video tape to acclimatise to the surroundings for about one hour.

For example, when bringing the VIEWCAM indoors after skiing, place it in a plastic bag.

Plastic bag

QBe sure to tightly seal the plastic bag containing the VIEWCAM.

WRemove the bag when the air temperature inside it reaches the temperature of the room.

•“Dew” warning feature

If dew forms, the word “DEW” flashes on the LCD monitor, and the power will automatically turn off in approximately 10 seconds.

QIf “DEW” flashes on the LCD monitor, remove the cassette, leave the cassette compartment open, and wait for a few hours to allow the VIEWCAM to acclimatise to the surrounding temperature.

WTo use the VIEWCAM again, turn on the power after waiting for a few hours. Be sure that “DEW” has disappeared from the monitor.

EDo not insert a cassette while “DEW” is flashing; this may result in damage to the tape.

RSince dew forms gradually, it may take 10 to 15 minutes before the dew warning feature engages.

Dirty Video Heads

Using the VIEWCAM when the video tape is dirty may cause the heads to clog, producing noise on the recorded image or preventing the image from being recorded at all.

If the video heads become clogged, the indicator appears on the screen. Contact your SHARP dealer for further advice or refer to page 59 “Before Requesting Service”.

Note:

•Video head cleaning can be done by using a commercially-available cleaning tape. However, excessive use of the cleaning tape may also cause damage to the video heads. Please read the instructions accompanying the cleaning tape carefully, before using it
