Onkyo TX SR343 Basic Manual

To connect your Onkyo TX-SR343 to a Bluetooth device, press the 'Bluetooth' button on the remote control. Ensure that the receiver is in pairing mode, then use your device to search for available Bluetooth devices and select 'Onkyo TX-SR343'.
First, check if the receiver is set to the correct input source. Verify that all speaker wires and audio cables are connected properly. Ensure that the volume is not muted or set too low, and check if the speakers are enabled in the setup menu.
To perform a factory reset, turn off the receiver. Then press and hold the 'CBL/SAT' button on the front panel while pressing the 'ON/STANDBY' button. When 'Clear' appears on the display, release the buttons and the receiver will reset to factory settings.
To update the firmware, download the latest firmware from the Onkyo website onto a USB drive. Insert the USB drive into the USB port on the receiver. Follow the on-screen instructions in the setup menu under 'Hardware Setup' > 'Firmware Update'.
Regularly dust the exterior to prevent dust accumulation. Ensure adequate ventilation to avoid overheating. Keep the receiver away from moisture, and occasionally check all connections and cables for any signs of wear or damage.
To improve sound quality, ensure speaker placement is optimized and use high-quality audio cables. Utilize the built-in equalizer settings to adjust the sound profile to your preference, and consider using bi-amping if your speakers support it.
