4. Troubleshooting
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 performance.
