Precautions
Use and storage
Do not subject the unit to severe shocks
The internal mechanism may be damaged or the body 
warped.
Do not block the ventilation holes
If the ventilation holes are blocked, not only are the 
characteristics not guaranteed, but also extreme 
degradation of the internal parts will likely result, causing 
defects of the camera.
For the locations of the ventilation holes, see the figures in 
“1-3 Locations and Functions of Parts” (page 11).
After use
Always turn off the power.
Use and storage locations
Store in a level, ventilated place. Avoid using or storing the 
unit in the following places:
• Places subject to temperature extremes
• Very damp places
• Places subject to severe vibration
• Near strong magnetic fields 
• 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 image sensor device. 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 camera.
Condensation
If you move the camera from a very cold place to a warm 
place, or use it in a damp location, condensation may form 
on the lens or inside the camera.
The camera has no built-in condensation indicator. If you 
find condensation on the body or lens, switch the camera 
off and wait for the condensation to disappear for about 
one hour.
Image sensor phenomena
The following phenomena that may appear in images are 
specific to image sensors. They do not indicate 
malfunctions.
White flecks
Although the image sensors are produced with high-
precision technologies, fine white flecks may be generated 
on the screen in rare cases, caused by cosmic rays.
This is related to the principle of image sensors and is not 
a malfunction.
The white flecks especially tend to be seen
• when operating at a high environmental temperature
Aliasing
When fine patterns, stripes, or lines are shot, they may 
appear jagged or flicker.
To forcibly open the shutter
Should the shutter to control incoming light to the image 
sensor not open, immediately consult your local Sony 
representative. 
If you want to continue shooting urgently, you can use the 
shutter emergency open screw (page 11) to forcibly open 
the shutter to a position that ensures an optical light path. 
For information about using the shutter emergency open 
screw, consult your local Sony representative. 
When setting the video format
It is recommended that the power be turned off and back 
on again after changing the video format.
