This unit contains a sensitive microcomputer, which under certain circumstances might fail to operate due to excessive noise interference. If this happens, press the DVD Receiver’s VIDEO 1 button and STANDBY/ON button at the same time until “CLEAR” appears in the DVD Receiver’s display. The DVD Receiver turns into the standby mode, then all the custom settings in the DVD Receiver’s memory will be erased. Please repeat the custom settings from the beginning.
