Onkyo HTP 938 Owner's Manual

To connect your Onkyo HTP 938 to your TV, use an HDMI cable from the HDMI OUT port on the receiver to the HDMI IN port on your TV. Ensure that both devices are powered off during the connection.
First, check that all speaker connections are secure. Ensure the receiver is set to the correct input source. Verify that the volume is turned up and not muted. If the problem persists, try resetting the receiver to factory settings.
To perform a factory reset, press and hold the "CBL/SAT" button on the front panel while pressing the "ON/STANDBY" button. Release both buttons when "Clear" appears on the display. The unit will then reset.
To update the firmware, connect the receiver to your network via Ethernet or Wi-Fi. Navigate to the settings menu, select "Firmware Update," and follow the on-screen instructions. Ensure to keep the receiver powered on during the update process.
The Onkyo HTP 938 is not directly compatible with wireless speakers. However, you can use a wireless speaker kit to convert the wired speaker outputs to wireless.
Use the AccuEQ calibration feature. Connect the supplied microphone to the receiver, place it at your listening position, and follow the on-screen instructions to automatically calibrate the speakers.
Regularly dust the exterior with a soft cloth. Ensure adequate ventilation to prevent overheating. Check and tighten speaker connections periodically. Avoid exposure to moisture and direct sunlight.
Ensure the receiver is well-ventilated and not enclosed in a tight space. Remove any objects blocking the vents. If the issue persists, consider using an external cooling fan.
Check the subwoofer settings on the receiver and ensure the subwoofer is properly connected. Adjust the crossover settings and increase the subwoofer level. Consider repositioning the subwoofer for better acoustics.
Place the front speakers at ear level and equidistant from the TV. The center speaker should be directly above or below the TV. Position surround speakers slightly above ear level, angled towards the listening area.
