Usage Precautions
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 a laser beam
become directed into the CMOS image sensors.
Do not subject to severe shocks
Damage to the case or internal components may result.
After use
Set the power switch to OFF.
Operation and storage environment
Store in a level, ventilated place.
If the unit gets wet, make sure it is completely dry before storage.
Avoid use or storage in the following places:
• Extremely hot or cold places
• Places with high humidity
• Locations subject to violent vibration
• Near strong magnetic fields
• In places where it receives much direct sunlight, or near heating
equipment
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.
Parts with limited life span
• 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.
• The life expectancy of 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.
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 a malfunction.
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 in high-temperature environment
• When the master gain (sensitivity) has been increased
The problem may be alleviated by executing automatic black
balance adjustment.
Aliasing
When fine patterns, stripes, or lines are shot, they may appear jagged
or flicker.
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
distorted.
In such cases, set the flicker-reduction function to AUTO
If the frame rate selected for recording is close to the power-supply
frequency, flicker may not be reduced sufficiently even if you
activate the Flicker-Reduction function. In such cases, use the
electronic shutter.
Focal plane
Owing to the characteristics of the pickup elements (CMOS image
sensors) for reading video signals, subjects that quickly move across
the screen may appear slightly skewed.
Flash bands
The luminance at the top and bottom of the screen may change when
shooting a flashlight beam or a light source that quickly flashes.
To prevent electromagnetic interference from
portable communications devices
The use of portable telephones and other communications devices
near this camera can result in malfunctions and interference with
audio and video signals.
It is recommended that the portable communications devices near
this camera be powered off.
Cleaning the Viewfinder
Use a dust blower to clean any dust from the surface of the screen.
