Cause and/or what to do about it
• The video heads need cleaning
(p. 60).
• The video heads need cleaning
(p. 60).
• The TV/VIDEO selector on the TV
isn't set to VIDEO (p. 19)
• If connected using the optional RF
unit the video channel has not been
selected.
• The speaker is switched off at the
menu (p. 15).
• Headphones are being used.
Cause and/or what to do about it
• The remote sensor is turned off
(p. 27).
• The batteries are dead or not inserted.
• It is turned off (p. 28).
• Check the screen displays (p. 73).
• 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).
• Remove the cable and then reconnect
it or turn the power off and back on
again.
