For setting : a remote control unit attached to product. For cancellation : JIG remote control unit (part number : PTU94023B) When the main body is

43、set to JIG mode and when the main body is under JIG mode, the remote control unit attached to product op- erates only in Remote Control Code 1. Since main body is in Remote Control Code 3 when it is shipped and just after its batteries are changed, Remote Control Code 3 needs to be changed to Remote

44、 Control Code 1. (1) Press the numeric button 1 of the remote control unit while pressing the SET UP button of the remote control unit. Then, press the ENTER button, and then release the SET UP button. (2) Press the PLAY button of the main body for five seconds or longer while the main body is in st

45、and-by mode, and a current remote control code of the main body is displayed in FL indicator of the main body. (3) While keeping the state of (2), press the STOP button of the remote control unit toward the main body. (4) The code that was set by the remote control unit blinks for 5 seconds, before

46、the code is set to the main body. When the FL indicator changes to DVD1, it shows that the remote control code has been changed to 1.
