Use a soft, dry cloth to wipe the exterior. Avoid using chemicals or abrasive materials. Ensure vents are free of dust to prevent overheating. Regularly inspect connections for any signs of wear.
The AVR-4802R does not have HDMI ports. You can use a digital optical or coaxial audio connection to link the receiver with modern TVs.
Connect additional speakers to the "Zone 2" or "Zone 3" outputs. Use the receiver’s on-screen menu to configure the zones and select audio sources for each zone.
Check the batteries and replace them if necessary. Ensure there are no obstructions between the remote and the receiver. Try resetting the remote by removing the batteries and pressing all buttons for 10 seconds.
Use the built-in test tone generator via the receiver’s menu. Adjust the speaker levels manually using the on-screen display to ensure balanced sound from all speakers.
Check the dimmer settings in the receiver’s menu to ensure the display is not set to off. If the problem persists, consult a technician as it might be a hardware issue.
