15、 Security Code 1. While in the Code Request mode, press key for three seconds while pressing the AUTO key. (- display goes off.) 2. Input “KCAR”, using the remote controller. Press 5 key twice, and then press key on the remote controller. (Enter “K”.) Press 2 key three (3) times, and then press key.

16、 (Enter “C”.) Press 2 key once, and then press key. (Enter “A”.) Press 7 key twice, and then press key. (Enter “R”.) 3. Then the security is cleared and the STANDBY mode is entered. 4.
