Instructions

1. • 1 Check the main power cord if the receiver fails to turn on. If it is unplugged or loose, securely plug it in to an electrical outlet. If this fails, try plugging the receiver in to another outlet. If the receiver starts, the previous outlet is damaged. Call an electrician to repair it. If this fails, try turning the receiver on with the remote. If this does not turn the receiver on, try turning it on with the power button on the receiver itself. If this works, change the remote's batteries.
     
   • 2 Leave the receiver in "Standby" mode if it immediately goes into "Standby" when you turn it on. With the receiver still in "Standby," unplug the main power cord. Wait for around 30 seconds, then plug the receiver back in.

   • 3 Check the audio cables if you experience sound issues. If they are loose or disconnected, securely reconnect them. If you still do not have any audio, press the "Input" left or "Input" right buttons on the front panel to select the appropriate input source. You can also set the receiver to automatically detect input signals and select the appropriate input source. To do this, access "Audio Select" from the main menu and select the "Auto" option.
     
   • 4 Try factory resetting the receiver if you experience persistent audio or video issues. Press the "Standby/On" button on the receiver's front panel. Press and hold the "Tone Control" button, then press "Standby/On" again. Select the "Preset" option, then choose "Reset." Press "Standby/On."
