Why can't my Yamaha RX-497 Stereo Receiver tune to the desired FM station automatically?
If your Yamaha Stereo Receiver isn't automatically tuning into the desired FM station, it could be because: * The signal is too weak. Try using a high-quality directional FM antenna. * Try using the manual tuning method.
What to do if my Yamaha RX-497 Stereo Receiver has no sound?
If you're not getting any sound from your Yamaha Stereo Receiver, there are a few things to check. First, ensure that all input and output cables are connected properly; if the problem continues, the cables may be defective. Next, make sure you've selected the correct input source using the INPUT selector on the front panel or the remote control. Also, verify that the SPEAKERS A/B switches are correctly set. Finally, ensure that all speaker connections are secure.
Why is my Yamaha RX-497 Stereo Receiver remote not working?
If the remote control for your Yamaha Stereo Receiver isn't working, consider these possibilities: * Ensure you are within a 6 m (19.7 ft) range and 30 degrees off-axis from the front panel. * Reposition the unit if direct sunlight or lighting is interfering with the remote control sensor. * Replace all batteries in the remote. * Check and switch the remote control ID or the unit’s ID if they do not match. * If the remote control code was not correctly set, try setting another code of the same manufacturer using 'LIST OF REMOTE CONTROL CODES'. * Use the supplied remote control for the components, even if the remote control code is correctly set, there are some models that do not respond to the remote control.
Why does my Yamaha RX-497 make buzzing and whining noises?
If you're hearing buzzing and whining noises from your Yamaha Stereo Receiver, a nearby TV set could be the cause. Try moving the unit away from the TV set.
Why aren't BASS, TREBLE, BALANCE and LOUDNESS controls affecting my Yamaha RX-497 Stereo Receiver?
If adjusting the BASS, TREBLE, BALANCE, and LOUDNESS controls doesn't change the tonal quality on your Yamaha Stereo Receiver, the PURE DIRECT button may be activated. Turn off the PURE DIRECT button to regain control over these settings.
