TX-8470 Troubleshooting: Others

Multi-zone function
Cannot ZONE-output the audio of externally connected AV components
• To output audio from an externally connected AV component to ZONE 2, use an analog audio cable for connection. Note that ZONE 2 output is not possible with the connection using an HDMI cable, digital coaxial cable, or digital optical cable.
Others
• If the audio signal is from the NET input selector, the zone output is not possible for DSD audio signals.
Remote Controller
• Make sure that the batteries are inserted with the correct polarity.
• Insert new batteries. Do not mix different types of batteries, or old and new batteries.
• Make sure that the sensor of the main unit is not subjected to direct sunlight or inverter-type fluorescent lights. Relocate it if necessary.
• If the main unit is installed in a rack or cabinet with colored-glass doors, or if the doors are closed, the remote controller may not work normally.
Display
The display does not light up
• When the Dimmer function is working, the display may go dim. Press the DIMMER button, and change the brightness level of the display.
• The display is turned off when the Pure Audio listening mode is selected. ( →p10, 15)
Others
Strange noise can be heard from the unit
• If you have connected another device to the same outlet as this unit, strange noise may occur under the influence of the device. If the symptom is remedied by removing the power plug of the other device from the outlet, use different outlets for this unit and the device.
