There is no access to a
drive in the Removable
drive bay. This can be
accompanied by an error
message from the
Windows operating
system. There is a problem with
the SSD/HDD currently
inserted in the drive, or
the drive bay itself is
faulty. 1. Unlock the lock switch and remove the SSD/
HDD. Insert it again and lock the lock switch.
Watch the drive lights turned on.
2. Try another SSD/HDD and watch the drive
lights turned on.
Problem Possible Causes Corrective Actions
A channel displays
black at the end of the
clip. The channel is in E to E
mode and there is no
video signal present at the
input. Verify that you have a valid input signal.
P1/P2 channels have a
dissimilar video display
when no clip is playing. One channel is in E to E
and the other channel is
not. If similar display is required, configure P1/P2
channels the same.
The picture level
modulates at a particular
frequency. There is excessive hum
riding on the video input
signal. The automatic
gain control (AGC)
circuits will tend to
modulate the picture level
at that frequency in an
attempt to compensate for
the problem. Check the video input signal for excessive hum.
