Onkyo TX DS494 Instruction Manual

To reset the Onkyo TX DS494, turn off the receiver. Press and hold the "VIDEO 1" button, then press and hold the "STANDBY/ON" button. Release both buttons when "CLEAR" appears on the display, indicating the reset is complete.
Ensure that the speaker wires are properly connected to both the receiver and the speakers. Check that the receiver is not on mute and that the correct input source is selected. Also, verify that the volume level is turned up.
Connect the receiver's "Monitor Out" to the TV's video input using an appropriate cable (e.g., HDMI, component, or composite). Ensure the TV is set to the correct input source to receive the signal from the receiver.
Regularly dust the exterior with a soft, dry cloth. Avoid using abrasive materials or solvents. Ensure that the ventilation holes are not obstructed to maintain proper airflow and prevent overheating.
The receiver may be overheating or experiencing a power issue. Ensure it has adequate ventilation and is not placed in a confined space. Check for any loose connections and verify that the power supply is stable.
Refer to the remote control's manual to find the correct codes for your devices. Enter the programming mode by pressing the appropriate device button (e.g., TV, DVD), then enter the code using the number pad. Test the remote to ensure it controls the device.
The Onkyo TX DS494 does not have built-in Bluetooth. You can use an external Bluetooth adapter connected to an available input to stream audio from a Bluetooth device.
Connect the speakers to the corresponding speaker terminals on the receiver. Use the setup menu to configure the speaker settings, including size, distance, and level calibration, to optimize audio performance.
Check if the display dimmer function is activated. If so, adjust it using the remote control or the front panel. Ensure the receiver is properly connected to the power outlet and try resetting the unit.
The Onkyo TX DS494 does not support firmware updates as it is an older model. For any functionality improvements, consider consulting Onkyo's support for possible hardware upgrades or alternatives.
