functioning pixel ratio of at least 99.99%. Thus a
very small proportion of pixels may be "stuck",
either always off (black), always on (red, green,
or blue), or flashing. In addition, over a long
period of use, because of the physical
characteristics of the liquid crystal display, such
"stuck" pixels may appear spontaneously. These
problems are not a malfunction. Note that any
such problems have no effect on recorded data.
Notes about the display
• Pictures on the LCD monitor may be distorted
by the following operations:
—Changing the video format
—Starting playback from the Thumbnail
screen
—Reversing the LCD monitor
File fragmentation
If pictures cannot be recorded/reproduced
properly, try formatting the recording medium.
While repeating picture recording/playback with
a certain recording medium for an extended
period, files in the medium may be fragmented,
disabling proper recording/storage. In such a
case, make a backup of clips in the medium then
perform formatting of the medium using [Format
Media] (page 60) in the [OTHERS] menu.
Consumable parts
The fan and battery are consumable parts that will
need periodic replacement.
When operating at room temperature, a normal
replacement cycle will be about 5 years.
However, this replacement cycle represents only
a general guideline and does not imply that the
life expectancy of these parts is guaranteed. For
details on parts replacement, contact your dealer.
AC adapter and electrolytic capacitor
The life expectancy of the AC adapter and the
electrolytic capacitor is about 5 years under
normal operating temperatures and normal usage
(8 hours per day; 25 days per month). If usage
exceeds the above normal usage frequency, the
life expectancy may be reduced correspondingly.
Batteries
i) For safety, use only the Sony battery packs and
AC adaptors listed below.
BP-U30/BP-U60/BP-U90/BP-U60
ii) The battery terminal of this unit (the connector
for battery packs and AC adaptors) is a
consumable part.
Power may not be supplied to the unit properly
if the pins of the battery terminal are bent or
deformed by shock or vibrations, or if they
become corroded due to prolonged outdoor
use.
Periodic inspections are recommended to keep
the unit working properly and to prolong its
usable lifetime.
Contact a Sony service or sales representative
for more information about inspections.
