Is some other AV device directly connected to the AV/S input/output jack of
VDR-M30?
If the AV device is connected via several other devices, such as AV selector, the

of devices through which the video signal is transmitted, or connect AV device
directly.

Depending on video game or PC, image cannot be recorded on VDR-M30.
Has brightness of LCD screen been adjusted?
Stop recording and adjust the brightness.
Is VDR-M30 being used outdoors?
Use the viewfinder. When using LCD monitor, adjust angle so that LCD screen
is not exposed to direct sunlight.
The panels used for LCD monitor and viewfinder of VDR-M30 are produced
using highly precise technology. However, 0.01% or less of total pixels may not
light (black dots) or may remain lit (red, blue, green dots). (The effective amount
of pixels on LCD panel is 99.99% or more.) This shows the limitations of the
current technology, and does not indicate a fault that will interfere with the
operation of LCD panel or operation of VDR-M30.
Is it difficult to use auto-focus with the subject?
Focus manually.
Does "MF" appear?
The VDR-M30 is set to manual focus. Focus the subject manually, or release
