Problem
[] The wireless controller doesn't work.
[] The tally lamps don't flash.
[] There are air bubbles inside the lens.
[] The camera malfunctions.
[] The viewfinder displays are uncleal:
[] The DV cable is connected correctly, but
there's nothing in the display.
[] The lens is attached, but LENS continues to
flash in the viewfindel:
Cause and/or what to do about it
• The remote sensor is turned off(p. 21).
• The batteries are dead or not inserted.
• They are turned off (p. 21).
This is unlikely, but may happen if you use the
camera in places where the air pressure is low, in
an airplane for example. The bubbles will
disappear a week or so after you return the
camera to normal atmospheric pressure.
External interference may cause the camera's
microprocessor to malfunction temporarily. If
random letters appear in the display or if normal
operation is interrupted, remove and then replace
the power source (and if necessary, the back-up
battery).
• The EYE POINT SELECT switch is set to FAR
(p. 11).
• The viewfinder focusing ring needs a@lsting
(p. 11).
• Remove the cable and then reconnect it or turn
the power off and back on again.
• Make sure the lens has clicked fully into
position. If necessary, turn the POWER dial to
OFF, remove the lens and retry (p. 9).
About the LCD Viewfinder
Liquid Crystal Viewfinders use extremely high-precision technology, but there will be pixels which do not
light up or which are continuously lit. This is not an error and will not affect the recording.
About the CCD
Due to the construction of the CCD, in low-light recording using the slow shutter or gaining up, small
specks of light may become visible in the viewfinder. In such cases, increase the shutter speed, reduce the
gain or use an additional light source such as a video light.
