4.1 In Case of Trouble
There are no field serviceable parts or circuits in the device. If you
think that the device is malfunctioning, please first make sure that
all your connections are solid, and check the state of the LED’s on
the front of the unit to access the mode it is in.
If you still cannot overcome the problem, disconnect the video and
audio input connections from the unit. Unplug the power from the
unit and after a few seconds reconnect power. Connect your audio
and video signals after the unit is powered up. Check
