Troubleshooting—Continued
The remote controller doesn’t work properly.
• Make sure the batteries have been installed with the correct polarity (+/–) (see page 9).
• Replace both batteries with new ones. (Do not mix different types of batteries or new and old batteries.)
• The remote controller is too far away from the T-4555, or there’s an obstacle between them (see page 9).
• The T-4555’s remote control sensor is being subjected to bright light (inverter-type fluorescent light or sunlight).
• The T-4555 is located behind the glass doors of a audio rack or cabinet.
• The T-4555 and remote controller may be set to different remote control IDs. Set the T-4555’s remote control ID first,
and then set the remote controller to the same ID (see page 23).
Interactive control with other Onkyo -capable components is not working.
• Make sure the cables and analog audio cables are connected correctly (see page 12). Connecting only an cable
won’t work.

Others
The T-4555 contains a microcomputer for signal processing and control functions. In very rare situations, severe
interference, noise from an external source, or static electricity may cause it to lock up. In the unlikely event that this
should happen, unplug the power cord, wait at least 5 seconds, and then plug it again.
