Beep does not sound:
• Off is selected for Beep options > Beep on/off (0 263).
• Camera is in quiet shutter-release mode (0 78), or movie is being
recorded (0 164).

quality (0 99, 243).
Sound is not recorded with movies: Microphone off is selected for Movie
settings > Microphone (0 169).
Live view ends unexpectedly or does not start: Live view may end automatically
to prevent damage to the camera’s internal circuits if:
• The ambient temperature is high
• The camera has been used for extended periods in live view or to
record movies
• The camera has been used in continuous release modes for extended
periods
If live view does not start when you attempt to start live view, wait for the
internal circuits to cool and then try again.
Note that the camera may
feel warm to the touch, but this does not indicate a malfunction.
Image artifacts appear during live view: “Noise” (randomly-spaced bright
pixels, fog, or lines) and unexpected colors may appear if you zoom in on
the view through the lens (0 53) during live view; in movies, the amount
and distribution of randomly-spaced bright pixels, fog, and bright spots
are affected by frame size and rate (0 168).
Randomly-spaced bright
pixels, fog, or bright spots may also arise as a result of increases in the
temperature of the camera’s internal circuits during live view; exit live
view when the camera is not in use.
