Restoring the Default settings
To reset the DR-L30 to its factory default settings, If the main unit is set to standby, press and hold both SURROUND and ¢ on the main
unit for 2 seconds or longer.
Because the unit contains a microcomputer to provide advanced functions, it may malfunction due to external noise or static electricity.
If this happens, press the POWER switch on the unit and then press it again after about five seconds.
