Dew Formation

l 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.

l 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:

l when moving the VIEWCAM from a cold

place to a warm place,

l when placing the VIEWCAM in a cold room

which is then heated rapidly,

l when moving the VIEWCAM outdoors from

an air conditioned room,

l when placing the

VIEWCAM in the direct

path of air blowing from

an air conditioner,

l when placing the

VIEWCAM in a humid

room.

”

l 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 acclimate to

the surroundings for about one hour.

For example, when bringing the VIEWCAM

indoors after skiing, place it in a plastic bag

and allow it to adapt to room conditions for

some period of time.

Plastic bag

Be sure to tightly seal the plastic bag

containing the VIEWCAM.

Remove the bag when the air temperature

inside it reaches the temperature of the sur-

roundings.

l “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.

If the word “DEW” flashes on the LCD

monitor, remove the cassette, leave the

cassette compartment open, and wait

several hours to allow the VIEWCAM to

acclimate to the surrounding temperature.

To use the VIEWCAM again, turn on the

power after waiting for several hours. Be

sure that the word “DEW” has disappeared

from the monitor screen.

Do not insert a cassette while the word

“DEW” is flashing; this may result in damage

to the tape.

Since dew forms gradually, it may take IO to

15 minutes before the dew warning feature

engages.

l How to maintain high recording quality.

If used in a variety of places, eventually your

VIEWCAM may not function properly due to

accumulation of dirt on the head drum. Avoid

the following as much as possible when using

your VIEWCAM.

1) Dew formation on the head drum.

2) Using a damaged or soiled video tape.

3) Use in a humid or dusty place.

l When the video heads become clogged.

Using the VIEWCAM when the video tape is

dirty may cause the head to clog, producing

noise on the recorded image or preventing

the image from being recorded at all.

Under such circumstances, contact the

nearest SHARP service centre or your dealer

for further advice.

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.
