Q20: My unit stopped working and displays "U99".

line
Answer:
The "U99" error code signifies a "general communications failure."
It is not associated with one specific problem.
It can be related to the version of firmware your DVD recorder is currently using and it has been associated with the TV Guide on screen guide.

If your unit displays U99, turn the power off-unplug the
unit for 5 minutes, and reconnect the power.

If U99 reoccurs, please contact the Global Service Center Network for assistance.
