About the LCD panels
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 present.

Characteristics of CCD sensors
The following effects may appear in the image. They are
characteristic of camcorders using CCDs (charge coupled
devices), and do not indicate a malfunction.

Bright or dark points of light
A CCD is made with high-precision technology. However,
minor bright or dark points of light (red, blue, or green)
may sometimes appear. This caused by the structure of the
CCD and is not a malfunction.
In this case, adjustment of black balance may help to
improve this problem.

Vertical smear
When shooting a very bright object, such as a light, the
highlight tends to produce vertical tails. This effect is
much reduced in this camcorder. (Use of the electronic
shutter increases this effect.)

White flecks
White flecks may appear on the screen during use under
high-temperature conditions. White flecks may also
appear under normal temperature conditions if the
sensitivity is increased (especially to +18 dB or higher).

Aliasing
When patterns of stripes or lines are shot, they may appear
jagged.

Condensation
If you move the camcorder from a very cold place to a
warm place, or use it in a damp location, condensation may
warm place, or use it in a damp location, condensation may
form on the drum. Then, if the camcorder is operated in
this state, recording and playback may not be performed
properly.
Do the following to prevent this from happening.

• Whenever you turn on the power, check that the HUMID
indicator does not appear on the color LCD. If it appears,
wait until it disappears before inserting a cassette.
