Sony PMW-F55 Operating Instructions Manual page 102

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 monitor
• Do not leave the LCD monitor facing direct
sunlight, as this may damage the LCD monitor.
• Do not press/swipe the LCD monitor forcefully,
or leave objects on the LCD monitor, as it may
cause a malfunction, such as picture
irregularity, etc.
• The LCD monitor may become warm in use.
This is not a malfunction.
About the LCD panels
The LCD panel fitted to this unit is manufactured
with high precision technology, giving a
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.
On condensation
If the unit is suddenly taken from a cold to a warm
location, or if ambient temperature suddenly
rises, moisture may form on the outer surface of
the unit and/or inside of the unit. This is known as
condensation. If condensation occurs, turn off the
unit and wait until the condensation clears before
operating the unit. Operating the unit while
condensation is present may damage the unit.
102 Important Notes on Operation
Phenomena specific to CMOS image
sensors
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
temperature
• when you have raised the master gain
(sensitivity)
• when operating in Slow-Shutter mode
Aliasing
When fine patterns, stripes, or lines are shot, they
may appear jagged or flicker.
Focal plane (PMW-F5 only)
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 (PMW-F5 only)
The luminance at the top and bottom of the screen
may change when shooting a flashlight beam or a
light source that quickly flashes.
Flicker (PMW-F5 only)
Shooting under the lights of a discharge lamp
such as a fluorescent lamp, sodium-vapor lamp,
mercury-vapor lamp, etc., may cause flickering,
color change, or vertical stripes.
Note on the display
• Pictures on the viewfinder screen may be
distorted by the following operations:
—Changing the video format
—Starting playback from the Thumbnail
screen
• 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
