Troubleshooting
Remote Controller
Make sure that the batteries are installed with the correct polarity.
Install new batteries. Do not mix different types of batteries, or old and new
batteries.
Make sure that the unit is not subjected to direct sunshine or inverter­type
fluorescent lights. Relocate if necessary.
If the unit is installed in a rack or cabinet with colored­glass doors or if the
doors are closed, the remote controller may not work reliably.
After operating the Multi­zone function (for compatible models only), the remote
controller may have switched to the mode for operating ZONE output audio.
Check "Multi­zone" in "Playback" in the Basic Manual to switch the remote
controller back to the mode for operating in the main room.
