The HT-R490 contains an internal microcomputer that performs high-level operations. However, on extremely rare occasions, noise or interference from an external source or static electricity may cause faulty operation. If this occurs, unplug the power cord from the wall outlet, wait five or more seconds, and then plug it back in. This should correct the situation.

*To reset the surround mode and other settings to the factory default settings, hold down the VIDEO 1 button with the HT-R490 turned on and then press the SPEAKERS A button. “CLEAR” appears in the front display and the HT-R490 enters the standby state.
