Enter the test mode. (See (1) How to enter the testmode.)2. Press the SRC key to set All OFF.3. Press and hold the AUDIO key for 1 second to entermenu mode.4. Press the FM/AM key to select “SECURITY“.5. Press and hold the Track Up/Down for 2 seconds.6. Enter the code by pressing the Preset 1, 2, 3 and 4keys.Example: To enter “3510“,Press the Preset 1 key 4 times. Press the Preset 2 key 6 times. Press the Preset 3 key 2 times. Press the Preset 4 key once.7. Press and hold the DISPLAY key for 3 seconds todisplay “APPROVED“.8. Quit the test mode (See (2) How to exit from the testmode.)(7) How to clear the simple security code (K type only)1. While the code is requested, press and hold the DISPkey and press and hold the VOL Up key for 3 sec-onds.(“-“ disappears.)2. Enter “KCAR“ from the remote control unit. (Sameoperation as the '98 model) Press numeric key 5 twice then press the Track Upkey. (This enters “K“.) Press numeric key 2 three times then press the TrackUp key. (This enters “A“.) Press numeric key 2 once then press the Track Upkey. (This enters “A“.) Press numeric key 7 twice then press the Track Upkey. (This enters “R“.)3. The security is canceled and the unit enter
