Important Notes on Operation





• In direct sunlight or close to heaters for

extended periods

To prevent electromagnetic interference from
portable communications devices
The use of portable telephones and other
communications devices near this unit can result
in malfunctions and interference with audio and
video signals.
It is recommended that the portable
communications devices near this unit be
powered off.

Note on laser beams
Laser beams may damage the CMOS image
sensors. If you shoot a scene that includes a laser
beam, be careful not to let the laser beam be
directed into the lens of the camcorder.

About the LCD panels

The LCD panels are manufactured with
extremely high-precision technology that yields
effective pixel rates of 99.99% or higher.
However, very rarely, one or more
pixels may be permanently dark or permanently
lit in white, red, blue, or green.
This phenomenon is not a malfunction. Such
pixels have no effect on the recorded data, and the
unit may be used with confidence even if they are

Phenomena specific to CMOS image

The following phenomena that may appear in
images are specific to CMOS (Complementary
Metal Oxide Semiconductor) image sensors.
They do not indicate malfunctions.

White flecks
Although the CMOS image sensors are produced
with high-precision technologies, fine white
flecks may be generated on the screen in rare
cases, caused by cosmic rays, etc.
This is related to the principle of CMOS image
sensors and is not a malfunction.

The white flecks especially tend to be seen in the
following cases:
• when operating at a high environmental


• when you have raised the master gain


• when operating in Slow-Shutter mode

When fine patterns, stripes, or lines are shot, they
may appear jagged or flicker.

If recording is made under lighting produced by
discharge tubes, such as fluorescent, sodium, or
mercury-vapor lamps, the screen may flicker,
colors may vary, or horizontal stripes may appear

In such cases, set the Flicker-Reduction function
to Auto mode (see page 52).
In some cases, such phenomena may not be
improved with the Flicker-Reduction function.
It is recommend to set the electronic shutter speed




sec. in 50-Hz areas and to




in 60-Hz


Focal plane
Owing to the characteristics of the pickup
elements (CMOS sensors) for reading video
signals, subjects that quickly move across the
screen may appear slightly skewed.

Flash band
The luminance at the top and bottom of the screen
may change when shooting a flashlight beam or a
light source that quickly flashes.

Note on the viewfinder display

• Pictures on the LCD monitor and viewfinder

screen may be distorted by the following

—Changing the video format
—Rec Review
—Starting playback from the Thumbnail


—Reversing the LCD panel
—Switching the Expanded Focus display

• When you change the eye direction in the

viewfinder, you may see primary colors red,
green, and blue, but this is not a defect of the
camcorder. These primary colors are not
recorded on any recording media.
