• Insert the plug securely. If the connection is incomplete, noise or malfunction may result.
Improper connection
Insert completely
•When you use a digital audio optical cable, do not bend it sharply nor coil it tightly.
•Bundling an audio connection cable with the power cord or speaker cord may degrade the sound quality.
