To connect your Onkyo TX-NR656 to a Wi-Fi network, press the 'Setup' button on the remote control, navigate to 'Network,' select 'Network Connection,' and choose 'Wi-Fi.' Follow the on-screen instructions to select your network and enter your password.
First, ensure that the speakers are properly connected to the receiver. Check if the receiver is set to the correct input source. Additionally, verify that the 'Mute' function is not activated and the volume is turned up. If the issue persists, try resetting the receiver.
To perform a factory reset, press and hold the 'CBL/SAT' button on the unit, then press the 'On/Standby' button. Hold both buttons until "Clear" appears on the display. Release the buttons, and the receiver will reset to factory settings.
Yes, you can stream music via Bluetooth. Activate Bluetooth on your smartphone, search for devices, and select 'Onkyo TX-NR656.' Ensure Bluetooth is enabled on the receiver by pressing the 'Bluetooth' button on the remote.
To update the firmware, press 'Setup' on the remote, navigate to 'Firmware Update,' and select 'Update via Network.' Follow the prompts to complete the update. Ensure the receiver is connected to the internet and do not power off during the update process.
Overheating may occur due to poor ventilation. Ensure that the receiver is placed in a well-ventilated area and not stacked with other devices. Check for dust buildup and clean the vents if necessary. Consider using an external fan to improve airflow.
To enhance surround sound, use the built-in AccuEQ calibration system. Connect the supplied microphone, place it at the primary listening position, and run the calibration via the 'Setup' menu under 'Speaker Setup.' Adjust speaker levels manually if needed.
Connect the turntable to the 'Phono' input on the receiver if it has a built-in preamp. If not, use an external phono preamp between the turntable and receiver. Ensure the ground wire is connected to reduce hum.
Ensure your TV and HDMI cables support 4K. Connect your 4K source to the receiver's HDMI input. Press 'Setup' on the remote, navigate to 'HDMI Setup,' and enable '4K Upscaling.' Ensure the receiver's output is connected to the 4K-compatible HDMI input on your TV.
Turn off and unplug the receiver before cleaning. Use a soft, dry cloth to wipe the exterior. Avoid using chemicals or abrasives. Regularly check and clean dust from the vents to prevent overheating.
