The DTR-7.4 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 DTR-7.4 turned on and then press the 
Standby/On button. “CLEAR” appears in the front 
display and the DTR-7.4 enters the standby state.

When “All” is set for the digital format
