Characteristic Ccd Phenomena - JVC GY-HM790CHU Instructions Manual

Handling of SDHC Cards
The access lamp lights up in red when data on the SDHC
card is being accessed. Do not remove the SDHC card
during data access (such as recording, playback, or
formatting). Do not turn off the power or remove the battery
and AC adapter during access either.
Do not use or store the SDHC card in a place that is
subject to static electricity or electrical noise.
Do not place the SDHC card near locations that are
exposed to strong magnetic fields or radio waves.
Inserting the SDHC card incorrectly may result in damage
of this unit or the SDHC card.
We are not liable for any accidental loss of data stored on
the SDHC card. Please back up any important data.
Make use of the SDHC card within the prescribed
conditions of use.
Do not use it at the following locations.
Places that are subject to direct sunlight, high humidity or
corrosion, places near thermal equipment, sandy or dusty
places, or in a car under the sun with the doors and windows
closed.
Do not bend or drop the SDHC card, or subject it to strong
impact or vibration.
When formatting or erasing data using the camera
recorder, only the file administration information is changed.
The data is not completely erased from the SDHC card. If
you want to completely erase all of the data, we recommend
either using commercially available software that is specially
designed for that purpose, or by physically destroying the
SDHC card with a hammer, etc.
Do not dismantle or modify the SDHC card.
Do not touch the terminals with your hands or with a metal
object.
Do not allow dust, dirt, water, or foreign objects to adhere
to the terminals.
Do not remove the labels or stick other labels or stickers
on the SDHC cards.
Do not use pencils or ballpoint pens to write on the SDHC
cards. Always use oil-based pens.
If you format (initialize) the SDHC card, all data recorded
on the card, including video data and setup files, will be
deleted.
You are recommended to use cards that are formatted
(initialized) on this camera recorder.
● The SDHC card may be damaged if the camera recorder is
not operated correctly. Formatting (Initializing) the SDHC
card may allow it to operate correctly.
● SDHC cards that have been formatted (initialized) on other
cameras, computers or peripheral equipment may not
operate correctly. In this case, format (initialize) the SDHC
card on this camera recorder.

Characteristic CCD Phenomena

Smear and blooming
Due to the physical structure of CCDs, vertical streaking
(called "smear") may occur when shooting an extremely
bright light source or expansion of light (called "blooming")
may appear around it. Although the CCD employed in this
unit produces very little smear or blooming, these
phenomena may still occur when shooting a bright light
source.
Monitor Screen
Moire or aliasing
Stripes, lines or other fine patterns may appear jagged when
they are shot.
White dots
High temperatures can cause CCD sensor pixels to produce
white dots in the image. This is especially prominent when
boosting the sensitivity.
This is a characteristic of the charged-coupled device (CCD).
As far as possible, use this unit under conditions where the
temperature of this unit does not increase.
Copyright
Any recordings made on this camera recorder that are
played back for profit or public preview may infringe on the
rights of the owner of the recordings.
Do not use the recordings for purpose other than personal
enjoyment without prior consent from the owner.
