Troubleshooting-Continued Tuner Reception is noisy, FM stereo reception is noisy, or the FM STEREO indicator doesn't appear • Relocate your antenna. • Move the AV receiver away from your TV or com- puter. • Listen to the station in mono (page 48). • When listening to an AM station, operating the remote controller may cause noise. • Passing cars and airplanes can cause interference. • Concrete walls weaken radio signals. • If nothing improves the reception, install an outdoor antenna. Remote Controller The remote controller doesn't work • Make sure that the batteries are installed with the cor- rect polarity (page 12). • Install new batteries. Don't mix different types of bat- teries, or old and new batteries (page 12). • Make sure that the remote controller is not too far away from the AV receiver, and that there's no obstruction between the remote controller and the AV receiver's remote control sensor (page 12). • Make sure that the AV receiver is not subjected to direct sunshine or inverter-type fluorescent lights. Relocate if necessary. • If the AV receiver is installed in a rack or cabinet with colored-glass doors, the remote controller may not work reliably when the doors are closed. • Make sure you've selected the correct remote controller mode (pages 13-16). • When using the remote controller to control other manufacturers' AV components, some buttons may not work as expected. • Make sure you've entered the correct remote control code. • Make sure to set the same ID on both the AV receiver and remote controller (pages 69 and 71). Can't control other components • If it's an Onkyo component, make sure that the cable and analog audio cable are connected properly. Connecting only an cable won't work (page 36). • Make sure you've selected the correct remote controller mode (pages 13-16). • If you've connected an -capable Onkyo MD recorder, CD recorder, or next generation HDD-compatible component to the TAPE IN/OUT jacks, or a DS-A1 Remote Interactive Dock to the VIDEO 3 IN jacks, for the remote controller to work properly, you 78 must set the display to MD, CDR, or HDD (pages 44 and 73). • To control another manufacturer's component, point the remote controller at that component. • To control an Onkyo component that's connected via , point the remote controller at the AV receiver. Be sure to enter the appropriate remote control code first (page 73). • To control an Onkyo component that's not connected via , or another manufacturer's component, point the remote controller at the component. Be sure to enter the appropriate remote control code first (page 72). Recording Can't record • On your recorder, make sure the correct input is selected (e.g., digital or analog). • When the Pure Audio listening mode (not North American models) is selected, recording is not possible because no video signals are output. Select another listening mode. Others The sound changes when I connect my headphones • When a pair of headphones is connected, the listening mode is set to Stereo, unless it's already set to Stereo, Mono, Direct, or Pure Audio (not North American models). The speaker distance cannot be set as required • In some cases, corrected values suitable for home the- ater use may be set automatically. The display doesn't work • The display is turned off when the Pure Audio (not North American models) listening mode is selected. How do I change the language of a multiplex source • Use the "a. Multiplex" setting on the "Audio Adjust" menu to select Main or Sub (page 66). The functions don't work • To use , you must make an connection and an analog audio connection (RCA) between the component and AV receiver, even if they are connected digitally (page 36).
