Sound is distorted or sound volume decreases. Sound is excessively distorted. No preset channels are selected. • The radio wave is distorted. • Cars are running or airplanes are flying near the house. • There is a tall building or a mountain nearby. [The waves transmitted from the transmission center (direct waves) and the waved reflected by buildings or mountains (diffraction waves) interfere with each other causing multi pass distortion.] • The power cord is unplugged for a long time. Sound is reproduced from the speakers but not recorded. • The sound system you are trying to record is DTS or Dolby Digital surround. LATE NIGHT function cannot be used.

Recording Other Memory Preservation This unit does not require memory preservation batteries. A built-in memory power backup system preserves the contents of memory during power failures and even when the power cord is unplugged. The power cord must be plugged in order to charge the backup system. The memory preservation period after the unit has been turned off varies depending on climate and placement of the unit. On average, memory contents are protected over a period of a few weeks after the time the unit has been turned off. This period is shorter when the unit is exposed to a very humid climate. When incorrect operation is observed • The HT-R8230 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-R8230 turned on and then press the STANDBY/ON button. "Clear" appears in the front display and the HT-R8230 enters the standby state. 36
