If you have any problems with the unit, please check the troubleshooting table below.
This unit contains a sensitive microcomputer, which under certain circumstances might fail to operate due to excessive noise
interference. In such an event, disconnect the main plug from the electrical outlet and reconnect it after 5 seconds. Please also ensure
that all system connections are correct and secure.
If the problem persists, or if the symptom is not found in the troubleshooting table, disconnect the power cord, and notify your Onkyo
service station. Include your name, address, and telephone number, as well as the product name, model number (ED-205), serial
