5. Troubleshooting
There are no field serviceable parts or circuits in the device. If you
think that the device is malfunctioning, please first try to reset to
factory default settings:
5.1 Resetting the TVB-400 to Factory Defaults
To reset all parameters back to the factory preset value, press the
“Mode” and “Adjust” buttons simultaneously for over 10 seconds. The
‘Power’ led will turn off when the buttons are pressed and then turn on
again when the reset has occurred.
